Biomass heating system - Wikipedia

Benefits of biomass heating. The use of biomass in heating systems is beneficial because it uses agricultural, forest, urban and industrial residues and waste to produce heat and/or electricity with less effect on the environment than fossil fuels. This type of energy production has a limited long-term effect on the environment because the carbon in biomass is part of the natural carbon cycle

3) into the gas stream as a conditioning agent has found wide use in recent years. It is theorized that ammonia reacts with H 2 SO 4 contained in the flue gas to form an ammonium sulfate compound that increases the cohesivity of the dust. This additional cohesivity makes up for the loss of electrical attraction forces.
