HEAT GENERATING METHOD AND APPARATUS INCLUDING DEPOSIT DESULFURATION STEP USING FINE GRANULE ABSORBENT IN FLUDIZED BED

摘要

The present invention relates to a heat generating apparatus and method for reducing the release of sulfur and nitrogen oxides. Combustion 1 of fuel comprising sulfur and nitrogen oxides occurs, and this combustion effluent and new absorbent particles are injected into a turbulent zone 9 upstream of the adiabatic desulfurization zone 8 and thus obtained. The mixture passes through heat recovery zone 16. Some absorbents are recycled to the desulfurization zone, and the flow rates of the new and recycled absorbents are controlled such that the temperature in this zone is from 750 ° C to 1000 ° C.
