Oxidant-swirled fossil fuel injector for a shaft furnace

An injector for injecting a swirling oxidant around a fossil fuel into a shaft furnace has a converging nozzle to improve combustion of the fossil fuel and reduce carbon soot formation. Fossil fuels, for example pulverized coal, may be introduced into the blast passageway and/or raceway cavity of a...

Zusammenfassung:	An injector for injecting a swirling oxidant around a fossil fuel into a shaft furnace has a converging nozzle to improve combustion of the fossil fuel and reduce carbon soot formation. Fossil fuels, for example pulverized coal, may be introduced into the blast passageway and/or raceway cavity of a shaft furnace such as a blast furnace or cupola, to reduce the amount of coke needed for operation. Oxidant, which may be industrial grade oxygen, is swirled around the fossil fuel through a converging nozzle to improve the combustion of the fossil fuel thereby permitting increased substitution of fossil fuel for coke.
