对水处理固体废物用作燃煤锅炉炉内脱硫添加剂的机理与实验研究表明 ,水处理固体废物用作炉内燃煤脱硫添加剂时生成一些可以有效地催化脱硫反应 ,以及减缓高温下 Ca SO4分解速度 ,使燃煤脱硫过程的最佳脱硫温度更加接近煤燃烧温度 ,提高燃煤脱硫效率的物质 ,如 Fe2 O3、Si O2 、Al2 O3、K+、Na+等 ;并使得脱硫反应温度更加接近煤燃烧温度 ;当脱硫反应温度在 870～ 92 0℃、脱硫剂与水处理固体废物的重量比为 1∶ 1、Ca/S=2 .0等条件满足时 ,可以得到燃煤脱硫的最佳效果

The Mechanism and Experimental Research for theDesulphurization Additive of SWWT in Coal Combustion

It is shown from the mechanism and experimental research for the desulphurization additive for the solid waste in water treatment (SWWT)in coal combustion,the SWWT is a catalyst (the special substance is made in high temperature,for instance:Fe 2O 3?SiO 2?Al 2O 3?K +?Na + et al)for the desulphurization in combustion,and can decelerate decompose for CaSO 4 in high temperature.And the same time,the SWWT makes the optimum desulphurization temperature tend to the coal combustion temperature during the process of desulphurization in furnace.The optimum desulphurization effects can be gotten while the desulphurization temperature is in 870～920℃,the proportion between the SWWT and the limestone is 1∶1,and Ca/S=2.0.
