Can We Lower The Pm Limit Of Biomass Boiler

Biomass explained - U.S. Energy Information Administration (EIA)

Biomass contains stored energy from the sun. Plants absorb the sun's energy in a process called photosynthesis. When biomass is burned, the chemical energy in biomass is released as heat. Biomass can be burned directly or converted to liquid biofuels or biogas that can be burned as fuels. Examples of biomass and their uses for energy
