Pulverized Fuel Boiler Most coal-fired power station boilers use pulverized coal, and many of the larger industrial water-tube boilers also use this pulverized fuel. This technology is well developed, and there are thousands of units around the world, accounting for well over 90% of coal-fired capacity.
The raw coal is then fed into the pulverizer along with air heated to about 650°F / 340°C from the boiler. As the coal gets crushed by the rolling action, the hot air dries it and blows the usable fine coal powder out to be used as fuel. The powdered coal from the pulverizer is directly blown to a burner in the boiler.

Burning with wood and coal is not a new concept. In fact, this old concept is gaining new popularity in many areas with plentiful wood supplies due to its cost effectiveness and low impact on the environment. Choosing a HEATMOR furnace is a decision that you will only have to make once.
The firing method most commonly employed for wood-fired boilers with a steam generation rate larger than 100,000 lb/hr is the spreader stoker. In this boiler type, wood enters the furnace through a fuel chute and is spread either pneumatically or mechanically across the furnace, where small pieces of the fuel burn while in suspension.
Railroads without ready access to on-line coal mines stuck with wood fuel quite late. (At Promontory in 1869, the CP Jupiter was wood-fueled; the UP 119 was coal-fueled. 2. Yes. Usually required a different stack and front-end netting. 3. Oh yes! Typical "hogged" wood fuel is only around 3,200 BTU per pound, assuming a 50% moisture content.
Wood burners can be as low as 5% for open wood fireplaces up to 80% for the latest EPA certified wood burners. For propane and NG furnaces, I've used an up to date non-condensing furnace (85%). New models of condensing furnaces can be up in the 90% to 97% area.

Aug 12, 2014 · For example, England’s largest power plant has converted two of its six 650-MW boilers to use wood pellet fuel instead of coal. That plant is generating reliably and just as many megawatts are being generated from pellet fuel as from coal. The U.S. has 428 pulverized coal power plants larger than 50 MW, typically aged.
Fuels commonly fired in boilers include fossil, biomass, and RDFs as well as other types of fuels and fuel combinations. Coal, petroleum-based oils, and natural gas are fossil fuels commonly fired in ICI boilers. However, other forms of solid, liquid, or gaseous fuel derived from these fossil fuels are sometimes included in this category. One
the wood. Higher heating values of wood can vary from 8,000 to 10,000 Btu per pound, bone dry. A cord of wood is a rough measuring unit; it is a stack of wood 4 feet high, 8 feet long, and 4 feet wide. A “good” cord of wood will be tightly packed. Pellet fuels are usually made from sawdust.

Logs, wood chips, brush clippings, and grasses all serve as woody biomass—renewable fuels suitable for producing heat and power. Burning woody materials is the original home heating system since there is evidence that prehistoric peoples burned woody materials in caves to provide heating—millennia before anyone recognized that coal or other materials could be burned to produce heat.
Jan 14, 2014 · Comparing with the gas, electrical heating stoves, the coal, wood and pellets stoves need to clean the ash of the fuel time from time. While on the other hand, the coal, wood and pellet stoves are obvious over the gas and electricity stoves in terms of the purchasing cost.

Wood from different trees has different heat values The table below provides a useful comparison. Wood fuel has typically less than half the calorific value of coal and smokeless fuel, so you must be prepared to use a greater volume of wood to heat your home or room, unless you use both wood and mineral solid fuel.
Coal, for instance, is a common boiler fuel. It can even be distinguished further between lumps of coal and crushed coal, with the latter kind burning more efficiently in most cases. Of course, we know that coal isn’t always the cleanest of fuels, although it has its advantages at times and remains a common source of energy for boilers.
