Biomass combustion simply means burning organic material. For millennia, humans have used this basic technology to create heat and, later, to generate power through steam. In the process of combustion, two ingredients (biomass and oxygen) are combined in a high temperature environment to form carbon dioxide, water vapor, and heat.
CH1.44O0.66 + 1.03 O2 = 0.72 H2O + CO2 (+Heat)
Note: CH1.44O0.66 is the approximate chemical equation for the combustible portion of biomass.
Provides a relatively cheap fuel source
Reduces reliance on fossil fuels
Provides self-sufficiency, even during blackouts (except for pellet stoves that require electricity to run the auger motors and fans)
Fuel quality and consistency can vary significantly
Produces more indoor and outdoor air pollution than conventional heating fuels, even with the use of advanced combustion technology
Creates the risk of fire and carbon monoxide poisoning
Can require cutting wood, as well as the skill to lay fires
