Independent chartered surveyors and architects company, Chalmers & Co, has installed a Windhager biomass pellet boiler at its new high street office in Haddington, near Edinburgh, marking the first installation of its kind in the UK.

Suppliers of renewable energy answers, Glendevon Fuel Corporation Ltd, installed the Windhager BioWIN – which has a performance assortment of 2.9kW to 78kW – into the Georgian building. Previously the British Linen Bank, the old stone vault within the building, was converted into a pellet store plus the adjacent office had a redundant hearth as well as smokestack suitable for positioning the wood boiler. Chalmers & Co anticipate a pellet delivery two or three times a year to the office based on the size of the store in addition to the expected demand on the boiler for heating. The BioWIN system is linked to an outdoor sensor which reads the external heat along with adjusts the warmth output of the boiler in line with the weather conditions, making the most economical use of the fuel.

Commenting on the installation, Jill Hardy at Chalmers & Co said: “Although the cost of installation in addition to the boiler tools exceeds that of a conventional gas boiler, nearly half was funded by means of The Forestry Commission under the Scottish Biomass Heat Scheme as well as the balance of the costs are covered by an interest free loan from the Energy Saving Belief. The environmental benefits are also much greater as we are not draining the earth’s finite unrefined resources.”

The Harman Stove are one of the industry leads in the US for biomass pellet stoves, however they have we not a key player in the biomass pellet boiler market. Yet Harman have now developed the PB105 wood pellet boiler. The PB105 shares many of the same features as the award winning Harman pellet stoves. These features include automatic temperature control plus automatic ignition, burn pot in addition to also automated pellet pro feeder. Good access to the burn pot is one more benefit, access to the in built hopper is also convenient, by a hopper storage capacity of 205lbs, which is accompanied with a large ash bin. All these features mean the PB105 will be a more energy adaptable in addition to reliable biomass pellet boiler. The maximum heat out of the boiler is just below 14 million Btu’s. This means the unit can provide warmth for a space of 2,500 sq.ft, in addition to has a combustion plus warmth recovery efficiency of 85% which is also very impressive.

The PB105 uses a 4 inch vent along with also has a three stage heat exchanger to capture as much heat as probable. The unit has a viewing window into the combustion chamber which is also the access point for the burn pot. The biomass pellet boiler also has an insulated water jacket to lessen warmth loss. The units operates on 120v plus has a fuse rating of 6A. To meet fire safety regulations the pellet boiler must be clearance around the back of the boiler of 6 inches, with 20 inches of clearance on both sides of the PB105, in addition to 36 inches at the front. There are a variety of additional options extras that can be fitted. These include an outside air temperature sensor, which can be very useful to investigate the efficiency of abode insulation, as well as also view the load on the boiler. Boiler pressure gauge and pressure relief values should be options to choose. Other options include water heat gauge plus boiler water drain off value. The PB105 is designed well, but time will tell if Harman will dominate the US biomass pellet boiler market the same way they currently dominate pellet stoves.

CATSKILL — Ruth plus Paul Brown hope to convince area residents to “join the heating revolution” in addition to switch from using common oil-fueled boilers to those fueled by means of wood chips or biomass pellets.

They have two residential indoor boilers in a trailer that are ready for demonstration to interested homeowners plus community organizations.

“Once people see them, they’re sold on them,” Ruth Brown said of the units.

They want to have demonstration units heating 30 homes in the Hudson Valley with December.

The Catskill couple has been working by Austrian corporation EvoTherm to bring the boilers to the Northeast plus Canada but they hope their corporation, called EvoThermUSA, will begin assembling the boilers locally.

The Browns have their eyes on the Greene County Industrial Development Agency facility on Schoharie Turnpike in Athens, as well as if they can move in, up to eight jobs could be shaped. If all goes to plan, on-site assembly of the boilers could begin as soon as June.

Brown plans on working by way of local businesses to install in addition to service the boilers. Individual boiler parts will be supplied by way of local boiler manufacturers.

The Browns are used to being pioneers. In 1996, they started Internet provider firm Franchise Communications, Inc. in addition to were the first to offer Internet service in the county.

Brown said that at the time he saw Internet service as a coming necessity. Now, renewable fuel is the way of the future, he said.

“This is the right product at the right time,” Ruth Brown added.

Paul Brown said he first saw wood chip- plus pellet-fueled boilers in Switzerland about 10 years ago. There, Switzerland native Ruth Brown said, government buildings, homes plus stores are heated with renewable fuels.

“I was blown away,” Paul Brown said.

“Why don’t we have that,” Ruth Brown said she wondered at the time.

About three years ago the Browns began working by EvoTherm in Austria. They have visited facilities in Europe that use the boilers along with the Austrian company’s employees have visited Catskill.

Paul Brown said chips can come from tree services, since chips can be made from hard or soft treetops, or low-grade biomass.

He said many landowners are looking for something to do by fallen trees on their properties or biomass that cannot be used for lumber.

The demand for biofuels as wood boilers become more in style can help provide a use for the trees that the Browns said would only be wasted.

“It is a perfect hand-glove put in with the wood industry,” Paul Brown said.

“This is definitely ‘going green,’” Ruth Brown said.

Pellets can purchased from retailers such as Lowes, or delivered in bulk. Brown said he has also had discussions by way of the owner of a local chipping business that may open soon.

Boilers come in unlike sizes, the largest of which puts out 1.5 million Btus of fuel plus the smallest 70,000 Btus.

The Browns said the boilers charge about $15,000, in addition to their payback period is about five or six years. The life-span of a boiler is about 20 years, they said.

Boilers need no more electricity to run or maintenance than a standard oil-run boiler, the Browns said, plus have a 93 percent efficiency rating.

Boilers may take three or four tons of pellets or 15 tons of chips a winter. The costs of chips as well as pellets, which come at $25 per ton plus $200 per ton, respectively, is not prohibitively expensive, the Browns said.

Fine ash must be removed weekly, Ruth brown said, adding that the boilers emitted no smoke.

“When there burns there is no smoke at all coming up out of the flue.”

The Browns are working by means of the Green County IDA as well as the Center for Economic Growth as well as by means of state representatives to bring their boilers to the Hudson Valley. Patent paperwork for the boilers must still be filed.

They are also working by way of the New York State Energy Research in addition to Development Authority to explore district heating, due to which two or more structures are heated from the same unit. Again, Ruth Brown said, many areas in Switzerland capitalize on district heating along with entire villages are connected to one heating unit.

The Browns showed their boilers at the Great Northeast Dwelling Show in Albany last month. Next weekend, they will visit a potential distributor in the Bronx.

EvoThermUSA is housed in the same building on Maple Avenue, in Catskill, the Browns’ extra corporation, as construction gear rental firm Cats Rental.

Paul Brown, who worked as a programmer along with traveled six months of the year before starting his Internet service, acknowledged that his business enterprises are not without risks. He traded a stable paycheck for the challenges of running every aspect of his own corporation. The risks have brought rewards, he said, as well as the career change allowed him to spend time at abode by Ruth plus their six children.

Brown said the boiler company developed as something to work on while the rental firm slowed during the winter and bringing the boilers to the United States just seemed like a good idea, he said.

“I never imagined I would be doing this,” he said.

For many people, the principle of heating via the use of pellets is still a very new concept. Many people are unaware of the reward of wood pellet fuels compared to log fires for example, along with the possibility to turn other biomass materials into energy pellets. At PelHeat we have been researching as well as experimenting by means of pellets since 2006. And we are strong believers that pellets will play a key role in changing the current trend of predominantly using fossil fuels to heat homes along with businesses.

In terms of the specific location as well as time, it is unclear. However around the 1970’s more than a few feed processors started to experiment processing wood into pellets as a fuel source. Again much like today, the catalysis for the idea came the rapid amplify in the fee of fuel from the cost of oil as well as gas. On the other hand today we have an additional driving factor of trying to lessen green house gases to slow climate change. Pellets have been produced from hay as well as grasses for animal feed since the start of the 20th century. In the 70’s when wood pellet fuels were first produced, some people thought a biomass pellet energy industry would grow rapidly from then onwards. However the fee of oil plus gas dropped, plus the appeal of pellets dropped as they do require more maintenance than a uncomplicated gas or oil burner. At the turn of the 21st century though, Sweden was well on its means to a dominant market share of pellet fuel heating. Because of the large amount timber processing in Sweden, there were large amounts of sawdust residue accessible cheaply as it was seen as waste, plus charge to remove. Central Europe now has a rapidly growing pellet market than it set to continue. This is a question many people today still disagree over, in addition to particularly by means of pellet production. At PelHeat we in general support the idea of a large number of smaller scale pellet manufacture plants and a few large scale pellet plants. The advantage by means of a small pellet plant positioned in the right location, way the overall energy used as well as charge to the consumer can be reduced. For case in point if a local area has enough resources to make pellet energy, and the local area has a demand for pellet energy. It is far more efficient to manufacture the pellets locally, along with then distribute locally. By means of a large pellet plant the raw matter travel long distances in addition to the pellet energy travels long distances. This results in a low overall energy efficiency through unnecessary transport. The other advantage by means of pellet fuels is that local pellet production and consumption can be very beneficial to the local economy and local community in general.

Since the start of the pellet fuels market, the emphasis has always been on wood, as well as only specific types of biomass to manufacture the lowest ash content pellet probable. On the other hand there is simple not ample of these resources to meet future market demands. Therefore other forms of wood plus biomass must be used to make pellet fuels. It also makes it easier for a local community to grow its own fuel resources or using other local waste resources from food crop production.

Generating biomass pellets requires a series of processes and a mixture of gear. You can create a wood pellet on both a small in addition to large scale, however the tools may change. A range of biomass resources can be processed into a biomass pellet, how the process in addition to gear may change. The first core step of pellet construction is raw material size reduction. The equipment used for size reduction depends on your chosen raw material. For large pieces of biomass, for case logs, a chipper or crusher will first be used to create the biomass into small chips. Yet for the pellet construction process, the biomass has to be reduced further in size. The chips will then be used in a hammer mill. A hammer mill has a set of hammers spinning around 4,000 rpm, as well as as they impact by the biomass chips, the chips shatter into smaller pieces. Once the chips have been decrease to a small enough particle size a fan remove the wood particles from the base of the hammer mill. and then a cyclone separator is used often by a rotary value to separate the particle from the air stream. Before pellet compression can take place, ample moisture must be removed so compression is possible. Therefore for most biomass used in pellet manufacture the wood particles must pass through a dryer before it can enter the pellet mill.

Once the sawdust has been dried down to between 10-15%, it is ready for the pellet mill. The two main designs of pellet mill are the flat die in addition to circle die. The flat die is the first design of pellet mill, invented at the beginning of the 20th century for feed pellet production. The sphere die design was invented later, by way of the improvements being more suitable for large scale pellet manufacture, lower fuel consumption in addition to decrease wear on consumables. However this flat die design is much cheaper to create as well as are so are the consumables such as the rollers along with die. Therefore today through these features, flat die designs are well-liked for small scale manufacture, along with ring dies are more accepted by way of large scale manufacture. There are several other designs such as hydraulic presses as well as double die designs. On the other hand these are on the other hand to reach mass market appeal, as their payback are not though proved in many aspects of pellet manufacture.

To improve biomass pellet quality and lessen the load on the pellet mill, steam conditioning is a common piece of biomass pellet apparatus. On the other hand steam conditioning is expensive and dangerous, so generally only used on large scale pellet plants. There are a number of pellet binders plus lubricants, for example manufactured from corn starch that can replicate the effects of steam conditioning in the pellet mill. Once the sawdust enters the pellet mill as well as is compressed through the die by way of the rollers, a combination of temperature in addition to pressure forms the pellet. When the pellets exit the pellet mill they are at around a hundred degrees. The pellets must be cooled before packaging along with storage to maintaince their shape plus integrating. Before storage the pellets should also be passed over a sieve to remove excessive fines in addition to dust. Excessive dust in the pellets can manufacture issues for some pellet stoves in addition to pellet boilers. Pellets are often packaged in addition to stored in plastic bags, however this is not encourage because of the waste, reusable bags produce much more sense.

Biomass pellet construction is a rapidly increasing industry, on both a small as well as large scale. The two main uses for biomass pellet fuel are the house heating market, in addition to providing fuel for power stations. Many coal power stations today use wood pellet energy in co-burning by means of coal to lessen the carbon emissions of the factory. This is a very affordable way for the power stations to meet carbon targets without having to invest in new equipment or processes. Other than the home heating market plus power stations, wood pellets are also used for pellet grills and for animal bedding such as horses. To make wood pellets, a series of processes and matter requirements are needed. One of the first key criteria to producing a quality biomass pellet is only a consistent raw matter can make quality consistent wood pellets. The consistent qualities the raw matter requires is a low moisture content as well as small particle size. The raw material also requires a ample proportion of unrefined lignin found in all biomass. Yet certain wood has more unrefined lignin than others. Wood generally has ample natural lignin for biomass pellet construction, yet other wood such as straws in addition to grasses may require another binder to hold the pellets together. Purpose manufactured binders are commonly manufactured from modified corn starch, the binder can also help by lubrication.

The first process to produce biomass pellets is size reduction. The wood raw material maybe in the form of logs, biomass chip or even sawdust. To decrease the biomass to a small uniform size a combination of a wood chipper plus then hammer mill solution will potential be required. Once the biomass has been reduced to 6mm particles or below, it is then ready for drying. Drying involves either a vent flash dryer or a rotary dryer. The general rule of thumb is that flash dryers are used form small scale production in addition to rotary dryers are used for large scale construction. Flash dryers are cheaper, yet are basic in addition to are not suitable for wood by means of a high moisture content such as virgin biomass. Rotary dryers are more expensive on the other hand they also have more control along with are suitable for virgin wood.

After size reduction along with drying the particles are then ready for pellet compression. As with drying, there are pellet compression solutions which are more suitable for small scale in addition to large scale manufacture. For small scale production, even abode use a flat die pellet mill is more practical along with affordable. The basic design of the flat die pellet mill means it is cheaper to manufacturer in addition to also maintain as the consumables are cheaper to manufacture. For large scale construction disc die pellet mills are commonly used as they use less electricity. When the sawdust enters the pellet mill, compression owing to the die generates both heat through resistance and pressure. A certain level of resistance is required to help the pellet form, however to much resistance will cause the biomass to become blocked in the die. When the pellets leave the die, they are very hot in addition to before they can be stored they require to be cooled to ambient air temperature. Also before packaging the pellets must be screened to removed fines from production.
