摘　　要：为了比较研究循环半干法、烟道流化床、炉内喷钙后烟气增湿活化法、喷雾半干法等脱硫工艺的机理及性能,综合比较分析了各工艺的脱硫反应时间、操作温度、钙硫比、可靠性、燃料适应性、装置占地、性价比等指标。分析结果表明循环半干烟气脱硫技术的燃料适应性、操作温度范围、性价比、运行可靠性等指标与其它半干法脱硫工艺相比具有一定的优势,因而更具推广价值和应用前景。In order to contrast and research the mechanism and performance of the desulphurization processes such as recycle semic-dry process,gas duct fluidized bed,lime spray in boiler and humidification activation behind boiler, semi-dry sprayer etc it is synthetically contrasted and analysed the indexes of the desulphurization processes including react time, operating temperature.Ca/S value, reliability, fuel applicability, equipment floor area, performance/price ratio and so on.The result shows that novel integrated desulphurization technology (NID) has predominance on the indexes such as fuel applicability, operating remperature, performance/price ratio, operating reliability and so on by contrasting with other semi-dry desulphurization processes.So NID is well worth to be expanded and applied.
