Sulfur equilibrium desulfurization of sulfur containing products of combustion

摘要

A method of combustion of a sulfur-containing fuel which substantially reduces the amount of gaseous sulfur compounds which would otherwise be emitted. A sorbent is injected into products of combustion in the temperature range of about 1600-2400 K. and above resulting from the combustion, gasification or the like, of a sulfur-containing fuel and controlling gas-sorbent particle mixing, gas diffusion, forward and reverse reaction kinetics, particle size, particle temperature, and sorbent particle residence time in the products of combustion to effect substantially maximum capture of sulfur by the sorbent particles and thereafter removal of the sorbent particles before any substantial amount of sulfur captured by the sorbent is lost back to the products of combustion from which it was removed.
