Carbon emissions from burning biomass for energy

biomass burning power plants emit 150% the CO 2 of coal, and 300 – 400% the CO of natural gas, per unit energy produced. These facts are not controversial and are borne out by actual air permit numbers. The air permit for the We Energies biomass facility (link) at the Domtar paper mill in Rothschild, WI, provides an example of how biomass and

12.2 Coke Production - US EPA

The blended coal mass is heated for 12 to 20 hours for metallurgical coke. Thermal energy from the walls of the coke chamber heats the coal mass by conduction from the sides to the middle of the coke chamber. During the coking process, the charge is in direct contact with the heated wall surfaces and develops into an aggregate "plastic zone".
