What to burn? The solid fuel minefield.

There are several fuel types available to the solid fuel user, coal, peat, wood logs, compressed wood products, smokeless coals etc.

With so much negative info in the press let’s take an objective look which is the right fuel for you to burn.

Firstly you must look at your appliance, follow manufacturer guidelines as burning the wrong fuel type can be dangerous and at the very least invalidate your warranty. If your chimney sweep is a registered professional it would pay to listen to them, generally sweeps are a hive of knowledge.

If you care about the environment, and you should, then you must focus on renewable fuels such as wood logs.

Selecting and purchasing wood logs

Ash and beech are some of the best wood logs to burn however most logs burn perfectly well if they are dry enough and have been adequately seasoned.

Wood should be purchased from a reputable supplier who will have to comply to regulations and a vested interest in planting more trees to replace what has been felled.

Wood logs must have less than 20% water content when they are burned. You can ascertain this several ways the easiest and probably most reliable is to purchase logs approved by Woodsure who will have done all of the eco checks and tested the moisture content in random batches. You will also be able to complain should the wood you purchased have too high a water content.

If you chose to purchase unseasoned logs then you must season them (typically for two years or more) after seasoning you must test the moisture content with an electrical conductivity moisture tester prior to using them, if they’re still wet it’s back to the seasoning pile. Again a moisture content of below 20% is required for efficient combustion and to prevent excess soot, increased risk and unnecessary environmental impact.

Users burning wet wood is one of the biggest problems and challenges our industry faces however it’s one of the easiest fixes too.

Why is mixing fuels a problem?

Wood and coal burn quite differently. Wood burns through a process of gasification where the volatile oils within become heated, turn to a gas, mix with oxygen above the log and eventually combust.

Coal on the other hand is primarily a carbon burn where oxygen must enter and mix from below the fuel as combustion takes place inside and not above the coal itself

There are distinct differences between the two types of appliances

Let’s look at some of the issues associated with the incorrect use of fuels

1/ Wood on top of coal

If we try to burn wood above a bed of coal we will need to open the top air intake drawing air above the coal and not through it. When this happens the coal which is burning poorly produces high levels of carbon monoxide and carbon dioxide, in doing so our wood gasses which should be bathed in oxygen are now shrouded in the same fire suppressant that is in the black fire extinguishers. The affect is compounded by the adequate heat from the coal, what happens is that the wood pyrolysis in the heat, volatiles hydrocarbons are emitted and become gaseous. Normally these hot gasses mix with oxygen and burn with the yellow flame we associate with wood however in the reduced oxygen environment above a coal bed the volatile gas emitted by the wood log will travel into the chimney where it will deposit as flammable creosote. The final issue when combustion temperatures and oxygen levels are too low is the later hotter stages of gaseous combustion will not effectively take place. During these later phases carbon soot particles should be burned, if they are not they will exit the chimney as fine dust pollution harming our air quality and shortening our lives.

2/ Coal on top of wood

We now understand that coal requires oxygen from below to burn effectively, think bellows in a foundry. If we burn wood below a coal bed we will have a situation where our coal is bathed in carbon dioxide leaving an incomplete burn. The second issue here is that wood produces lots of ash which in turn blocks the riddle grate further lowering the amount of available oxygen to the coal. If the coal used is smokeless coal then high levels of sulphurous compounds will also be emitted, these compounds are highly corrosive and will eat through stainless steel liners in no time. The one exception to the wood underneath coal scenario is kindling a fire with wood where it is very likely that the air intakes or even the door will be open in order to provide enough oxygen for both fuels for a limited time.

Historically blacksmiths used a bellows to pump air below the coal from under the fire bed. Nowadays they inject neat oxygen or use a pumped fan.

Slumbering

The term slumbering relates to the user loading the already burning appliance and then closing down the air supply in an attempt to make the fire burn for long periods, typically overnight.

There is a huge problem here and that is the fact that fuel requires oxygen for combustion. There are several results that occur when oxygen is limited in a combustion reaction, I’ll list a few.

Much of the volatile content within the fuel is emitted due to the heat but it does not combust, it rises up the flue coating the chimney with volatile fuel and greatly increases the risk of chimney fire and the requirement for sweeping, Many of the unburned hydrocarbons exit the chimney as smoke and pollute our planet.

Carbon requires lots of oxygen and heat for the particles to combust. When the oxygen supply is limited, dangerous pm2.5 and pm10 sized carbon particles are released. Many of these particles make it to the outside air as fine dust pollutants causing health problems such as respiratory and lung diseases.

Heat or lack of. In order for a fuel to release its stored heat, it must react with oxygen. Oxygen is the catalysing agent within the combustion reaction.

Cost. Slumbering will shorten the life of stainless steel liners, increase the need for servicing, sweeping and maintenance and reduce the heat value that you should get from the fuel making it less cost effective.

To conclude

Ideally you will burn only dry wood logs in an environment that has adequate air for moderate flaming combustion.

Adjust the air supply so that flames are not sucking up the chimney but doesn’t limit it too much. Smoke should not be visible in the firebox, only fire.

Add as much fuel as in needed to fill the fire box with flames, burning too much or two little fuel at a given time is another avoidable we can negate.

You can ask you profession chimney sweeps for tips on fuels and how to achieve moderate flaming combustion, fuel storage, type, sweeping frequencies and many other important factors surrounding burning practices.

The Importance Of Laser Cutting In London

Laser cutting is an innovation that uses a laser to cut materials. While regularly utilized for mechanical assembling applications, it is additionally beginning to be utilized by schools, independent ventures, and specialists.

Laser cutting works by coordinating the yield of a powerful laser most generally through optics. The laser optics and CNC (PC numerical control) are utilized to coordinate the material or the laser shaft created.

A business laser for cutting materials included a movement control framework to pursue a CNC or G-code of the example to be cut onto the material.

The engaged laser pillar is aimed at the material, which at that point either dissolves, consumes, disintegrates away, or is overwhelmed by a stream of gas, leaving.

Laser Cutting  is a flexible non-contact procedure to precisely cut a various scope of materials utilizing an extreme light emission. It has an immense bit of leeway over progressively conventional techniques in view of its speed, exactness and accuracy.

The laser slicing strategy gives the alternative to switch immediately between various applications and set-ups, sparing time and the need to run different machines.

What is optical Fibre cable and how does it work?

What does a Fibre Optic Cable Do?

The way in which we communicate has radically changed over the last two decades. Advancements in technology have led to a landscape where we can communicate with anyone in the world no matter where they are. And, more importantly, we can do this quickly and with minimal disruptions to quality. One of the driving forces behind this advancement is the availability of fibre optic cabling London.

What is a Fibre Optic Cable?

A fibre optic cable is similar, at least in aesthetic terms, to an electrical cable but its method of operation is very different. Containing long, thin strands of glass fibre that are housed within an insulated jacket, a fibre optic cable transmits light signals through its glass core. It’s common, within contemporary cables, to find up to a thousand fibres. And, the more fibres present, the greater the speed.

There are two main types of fibre optic cables:

Single mode Fibre:

Working with just a single light path, single mode fibre can transmit signals over distances of up to 100km. The electronics required to work with single mode fibre cables are expensive and are most commonly found in telephony applications, local area networks, cable TV and data cabling london.

Multimode Fibre:

These types of fibre optic cables differ to single mode fibre cables in that multiple light rays travel throughout the cable. This allows connections to be simplified and present a cheaper option. However, due to the light dispersion that takes place, the range on offer in multimode fibre cables is much reduced; the distance on offer is usually around a maximum of one km.

Fibre Optic Cables in Computer Networking

The backbone of any good computer network should always be fibre optic cables. Communication in business needs to be quick and it needs to be efficient. And fibre optic cables allow both these conditions to be met. Large files can be seamlessly transferred between users and communication via video conferencing can be delivered with a crystal clear, uninterrupted level of quality. And fibre optic cables are more than capable of supporting large numbers of employees. Therefore, fibre optic cables are a fantastic choice when it comes to setting up any computer network.

Advantages and Disadvantages of Fibre Optic Cables                                    

As with any product, fibre optic cables come with a number of advantages and disadvantages:

Fibre Optic Cabling Advantages:

High Bandwidth: Compared to other cables on the market, such as copper, fibre optic cables provide the highest bandwidth available for transmitting and receiving data.

Small Size: A major advantage of fibre optic cables is their small size. This not only helps you to save space, but allows for simpler organization of your network.

Distance: Fibre optic cables are able to take advantage of their low power loss to transmit data over large distances compared to rival cables.

Low Error Rate: The fibres within the cables are highly resistant to electromagnetic interference, so the risk of errors during transmission is significantly reduced.

Fibre Optic Cabling Disadvantages:

Install Issues: Fibre optic cable isn’t the easiest material to install due to its fragility. Bending the cables can easily damage the glass fibres and the thin jackets also mean that they are susceptible to being cut.

Costs: The many benefits of fibre optic cables do not come cheaply. And, compared to copper cables, they are much more expensive to purchase.

With these benefits it is of little surprise that fibre optics are fast becoming the cable solutions for choice for businesses that want reliable, fast connections.

For more information on what fibre cabling could do you for your business, don’t hesitate to get in touch.

Sara Leonor,Geometric Chairs, Laser cutting, 3D Printing

Originally from Spain, Sara Leonor moved to London in 2006 where she has worked as an interior designer and furniture maker ever since.

Her debut design the sculptural ‘Zeed’ chair, won her critical acclaim in 2010 and since then her work has continued to evolve. She now dedicates most of her time to designing artistic chairs of many shapes and colors that are inspired by geometric shapes.

Using a variety of materials such as wood, steel and acrylic, the results are unique shaped objects that are not only beautiful but serve as functional furniture.

We have had the pleasure of working with Sara for the last couple of years on some of her newest and most innovative designs.

Her latest project was an exercise of shapes, trying to make a chair that was very light and almost disappeared. The result is the stunning, eye-catching oTo and Bud chairs in neon yellow and electric blue

These chairs are extremely light with thin white frames that merge on a white background, enabling you to see through the frosted colored acrylic seat and back rest. Perfect for the summer to enhance any interior or outdoor area.

Sara’s technique is to first hand sketch her designs and then make miniature 3D printed prototypes. Selected designs are then manufactured as life size final products.

Laser cutting isn’t a new technique for Sara and she has been using it for her prototype models for the last 15 years. However, for her oTo and Bud chair series, it is the first time she has used laser cutting for an actual final product. And, she has told us that she is very happy with the results!

When asked about working with Swordfish she said, “Since I started working with you a couple of years ago I love how quickly you supply quotes and manufacture the actual orders. Your prices are very competitive and your attitude is excellent!”

How to Survive Your First Day of Agency Nursing

Even if you are a seasoned nurse, doing your first agency shift can still be daunting. Adjusting to a new working environment and working with a new healthcare team in a new routine can be overwhelming. This is especially true when as an agency nurse you are expected to perform the same duties as a facility nurse would, in a competent and timely manner with little or no orientation. Here are a few tips to help you successfully get through your first day of agency nursing:

Be Prepared

The day before your shift, get everything you need ready. Iron and hang your uniform, organize any pertinent documentation such as the instructions to your shift location and timesheets. Make sure you have your agency identification card. Prepare your lunch or snack so you don’t have to do this before leaving for your shift.

Get a Good Nights Rest

Make sure you sleep well and don’t let the stress of the following day keep you awake. Be confident within yourself. After all, you would not be put forward for shifts if your agency did not deem you fit for the job at hand. Moreover, being well rested will mean you are more focused and alert.

Plan Well for Travel

Account for traffic and travel issues and arrive early for your shift. This is important to ensure that the client is happy, that you have time to get associated with your new working environment, and so that you don’t miss the induction. You will also be more relaxed and not arrive rushed and stressed.

Introduce Yourself to the Management and the Staff you will be Working With

Build rapport with your new team as they will help guide you through all the things you need to know to be able to do your job efficiently.

Take Notes

Pay attention in your induction and write down any relevant information – this will help you adjust more easily and you can refer to your notes if at any stage you forget any of the information verbally passed on to you.

Don’t Be Too Hard on Yourself

Work like you would in any facility because although your co-workers will expect you to function like they do; they know that you won’t learn everything in a day. Do not put unnecessary pressure on yourself by trying to know everything the moment you step through the door. It will take a while for you to adjust to the new environment and their way of working.

Why should be I Seriously Care About Chimney Liners?

A chimney liner is the essential and critical part of the chimney. This has to be replaced on and off when there are breaks or damage noted. In older homes, there were clay tile liners used, as it can withstand extreme heat without any hindrance or damage. The performance is excellent and long lasting and holds the corrosive materials from passing through the flue. When comparing the cost efficiency it is very effective and favors many residential. The duration of the tile is a minimum of 50 years. 

Not all materials have only the positive side but, the installation is pretty costlier if build after the construction of the house. At present the tile liner is built along with the building, this may affect in terms of the cost and the process is tedious too. The simple tile liner if chips, has to be replaced using specialized equipment and by professionals who are specifically trained in this manner.    If the chimney contains crooked or offsets contamination, this makes the process tedious and stressful. The tile can crack in prolonged duration of use. To repair it definitely requires chimney sweep professional trained and holding a license on these works.

The new chimney lining creation in the inner wall may bring it back to the original shape but the flue in the inner surface of the chimney is out of shape. Instead of clay flue, a similar material is found in recent years that is, namely cast-in-place liners.

Insult tolerance is higher

Higher durability

Withstand high temperatures

Less creosote formation

Lon lasting (chance to stay up to 50 years)

The clay liner is more invasive than cast in place liners. The motor is used to mix the pumped and inflated rubber is placed in the chimney intact. But the motor is removed out. The bell-shaped form vibrates and pulls up through chimney pouring motor contents in the chimney. This motor forms around the bell and the flue lining opening is formed around the edge of the motor.

The metal flue liner is the made of stainless steel alloy and is available in different types and styles the two forms of metal liners are rigid and flexible. The rigid metal liner is straight with no off-set bends or deviations noted. While the flexible metal liners hold a lesser buildup since it is flexible (contract and expand) withstanding higher temperatures. At the same instance, they knock off the creosote formations too. The corrosion problem is most commonly noted in the metal liners, in turn, can be controlled by using the proper fuel as per the guidance of the manufacturer. Insulation materials around the chimney tolerate higher temperatures and prevent corrosion and torsion preventing the movement of the pipes. The chimneys that are non-flexible can be installed easily.

Thus, taking care of the chimney and preventing the health hazard and other major problems is a very serious matter of concern. These chimney liners prevent leakage and effusion. It is best to prevent the family from getting affected by breathing disorders, skin diseases, etc, which in turn are caused due to the chimney content and reluctance.

Chimney sweeping. Airborne dust dangers and dust extractors.

Hello chimney sweeps and industry professionals, todays article is about Hepa airborne dust extractors. We are going to explain; what they are?, what they do? Why we need one? And costs.

What is an airborne dust extractor?

An airborne dust extractors is a powerful adjustable, fan unit built within a casing. The casing houses a very large HEPA filter and a pre filter at the air intake end. They are generally mains electric powered and often of a size as to be portable.

What do they do?

As the name suggest an airborne dust extractor removes small dust particles from the working areas atmosphere. It accomplishes this by by catching them in a highly efficient HEPA filter.  A centrifugal fan draws in and then blows out air from the room in an action that recirculates its entire  volume many times removing harmful particles in the process.

Most units are also capable of depressurising a work area or space by attaching a hose to the exhaust and then routing said hose to the outside space. This can be invaluable when there is a lot of dust that you need to contain within one room or dust tent. In this scenario a vacuum is formed in the work area causing air to be drawn in through any available crack/holes. This action makes it almost impossible for dust to escape as the vacuum makes a one way road so to speak.

Health issues regarding fine dust.

It is very well documented that fine dust particularly particles between pm10 and pm 2.5 pose a significant health risk within the general population. This dust typically originates from industrial processes and combustion of hydrocarbon based fuels. It is estimated that around 37000 premature deaths are attributable to pm2.5 dust pollution in the U.K. each year (ref European Environment Agency figures published for 2012). This same fine dust is what Chimney sweep association UK chimney sweeps   clean from chimneys each day and as such we have a much higher risk from prolonged exposure and increased concentration.

Where would we use such a device when we already have clean process?

After  many years  of trials chimney sweeps association  have come to the conclusion that no matter how good or clean your process is there will still be a small amount of soot / dust that becomes airborne within the property. This can happen when unsealing, removing sheets, laying sheets, removing rods from the flue, spinning rods via rotary systems, soot that passes unseen through cloths during the sweeping process and simple sweeping up.  There might  even be some soot that makes its way to the wrong side of the vacuum filter occasionally which of course contaminates the workplace aka customers living room when you turn it on. For chimney sweeps, as a rule of thumb such a device can be used anywhere that there is an increased risk, when dust cannot be controlled by traditional methods, when applying fine dust product such as Cre-Away, in prestigious properties or simply all the time if you are of a cautious sensible nature. As chimney sweeps We might use a negative set up when we are removing a large nest from a large chimney and the flue  is blocked preventing the natural draught.

DC 500 Portable dust extractor

There are several devices on the market that serve the purposes above however the device that Chimney sweep association  have focussed on today is the DC500 dust cube manufactured by dust control. It is a quality device made from stainless steel. The dust cube is also light and durable. There are two filters; a l very large HEPA filter which sits inside the unit and a disposable pre filter which fits to the front grill. The unit is suitable for fine and hazardous dusts as small as 0.3 microns. Fine quartz dust and soot are both  good examples of dangerous fine dust.

The only real Negative of using a Dust extractor is the additional cost. Unfortunately many chimney sweeps are still to be convinced of the real need to use vacuum cleaners with adequate filtration or even high efficiency dust masks and as such for this group, a good H-rated HEPA vacuum and/or high efficiency mask should be top of the priority list. For those wishing for extra safety, lower the risk of having nasties in the air and add additional customer value, a dust extractor is an excellent addition to your ever growing sweeping tool kit and recommended by sweep safe as equipment to lower risk/exposure for chimney sweeps. The additional costs that you must factor over the unit itself is the replacement HEPA filters which will require changing infrequently and the pre filters that you will need to change regularly as keeping these clean will help prolong the life of the HEPA unit.
