【Abstract】 An experimental research is conducted of the mechanism of using solid waste from water treatment as a desulfurization additive during coal combustion. The experimental research results show that the above mentioned solid waste can effectively catalyze a desulfurization reaction and lower the CaSO 4 decomposition speed under high temperatures. As a result, the optimum desulfurization temperature during coal combustion can be made to further approximate the coal burning temperature, thereby enhancing the desulfurization efficiency during coal combustion and increasing the utilization rate of calcium. The use of the solid waste from water treatment as a desulfurization additive involves a simple implementation system and flow process. It is conducive to a decrease in emissions of solid waste from water treatment, thus alleviating pollution to water body. In addition, the emissions of SO 2 during coal burning can also be effectively diminished.更多还原
