炉内喷钙及尾部增湿活化脱硫的中间试验研究

A Pilot plant Study of Desulfurization by Way of In furnace Limestone Injection and Tail section Moisture Addition induced Activation

对炉内喷钙及尾部增湿活化脱硫技术进行了中间试验研究。株州烟煤的含硫量较低 ,当钙硫比为 2 6 7,增湿量为 18 6kg/h时 ,脱硫率达到 75 % ,吸收剂利用率为 2 8 1%。

A pilot plant study was conducted of the desulfurization technology by way of in furnace limestone injection and tail section moisture addition induced activation. In the case of Zhuzhou bituminous coal with a relatively low sulfur content a desulfurization rate of 75% can be attained with an absorbent utilization rate of 28.1% if the calcium sulfur ratio is 2.67 and the moisture addition 18.6 kg/h. Currently, this is enough to meet the desulfurization requirements of coal fired boilers.
