Abstract
The invention relates to the use of engineered fuel feedstocks to control the emission of sulfur-based, chlorine-based, nitrogen-based, or mercury-based pollutants, such as SO2, SO3, H2SO4, NO, NO2, HCl, and Hg that are generated during the combustion of fossil fuels, such as coal. Disclosed are novel engineered fuel feedstocks, feedstocks produced by the described processes, methods of making the fuel feedstocks, methods of producing energy from the fuel feedstocks, and methods of generating electricity from the fuel feedstocks.
Claims26
A method of generating energy comprising co-firing in a reactor an engineered fuel feedstock comprising at least two sorbents and at least two components derived from MSW, and at least one fossil fuel, wherein emission of at least one pollutant is less than the emission of said pollutant when the fossil fuel is fired in the absence of the engineered fuel feedstock, wherein the at least two sorbents includes at least one sodium-based sorbent and at least one calcium-based sorbent, and the engineered fuel feedstock further comprises an additive for reducing mercury emitted during co-firing in the reactor.
