Research status and progress of steam coal desulfurization technologies
MIAO Qiang
Abstract：In order to develop steam coal desulfuration technologies with proprietary intellectual property rights,the status of steam coal desulfuration technologies at home and abroad was introduced. The core processes and flows of dry,wet and semidry method flue gas desul-furation technologies were highlighted. The results showed that,the wet method was mature and realized a large-scale industrial applica-tion,while the complicated process increased cost. The dry method didnˊt have corrosion and condensation problems,but the desulfuration efficiency was lower. The desulfuration efficiency of semidry method was higher,while it wasnˊt suitable for large-capacity combustion de-vices. At last,the author pointed out that it should focus on desulfuration principle innovation,multiple-products process or multi-stage desulfuration process development which produced the byproduct of ammonium sulfate and magnesium sulfate fertilizers. The cheap,more efficient and multifunctional composite and recyclable desulfurizer,catalyst and absorbent as well as new assistive desulfuration technolo-gies should be determined as the key research fields.
