Burning wood and other biological materials for energy emits as much or more pollution than burning fossil fuels, including coal. Emissions are function of the fuel type, combustion temperature, and pollution controls, but in PFPI's analysis of air pollution permits in 7 states we have found that biomass burners are always more polluting than natural gas and are similar to coal
Biomass Boiler - an overview | ScienceDirect Topics
Biomass boiler is a kind of boiler with clean fuel, environmental protection, and low pollution. Facing the international community's increasingly serious punishment for using larger polluting boilers, biomass boiler's industrial application can well meet the sustainability development of boiler companies.

Biomass boilers are different from coal-fired boilers. The grate gaps of coal-fired boilers are too large for wood pellets. In biomass boilers, the wood pellets are gasified and fed by a hopper at a constant speed so that they can burn sufficiently.
Biomass power systems are typically below 50 MW in size, compared to coal-fired plants, which are in the 100- to 1,000-MW range. Most of today's biomass power plants are . direct-fired systems. The biomass fuel is burned in a boiler to produce high-pressure steam that is used to power a steam turbine-driven power generator.
Feb 29, 2016 · Converting from coal to biomass is a complex process with many moving pieces. For starters, the project was on an Army installation, so delivery hours were regulated and narrow. The timeline was also abbreviated; the project was slated to last only from August 2012 to April 2013, a brief amount of time for major construction.
Biomass cofiring projects do not reduce a boiler's total energy input requirement. In fact, in a properly implemented cofiring application, the efficiency of the boiler will be the same as it was in the coal-only operation. However, cofiring projects do replace a portion of the non-renewable fuel—coal—with a renewable fuel—biomass.
