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.
Claims29
An engineered fuel feedstock, comprising at least two sorbents and at least two components derived from MSW, wherein
- at least one sorbent is a sodium-based sorbent,
- at least one sorbent is a calcium-based sorbent,
- at least two components derived from MSW comprise about 5% (w/w) to about 50% (w/w) plastic and about 50% (w/w) to about 95% (w/w) fiber and contain substantially no glass, metals, grit, and noncombustible waste, and wherein the engineered fuel feedstock further comprises a sorbent for mercury reduction.
An engineered fuel feedstock, comprising about 52% fiber, about 13% plastic, about 9% calcium hydroxide, about 23% sodium bicarbonate, about 0.13% calcium bromide, about 2.3% urea.
