影响型煤固硫率的主要因素

INFLUENCE FACTOR ON SULFUR RETENTION OF BRIQUETTE

大量燃煤伴随而来的环境问题是SO2污染及酸雨．固硫型煤可降低SO2污染，改善大气环境质量，是一项投资少、见效快的实用技术．文中着重研究了固硫剂类型、Ca／S摩尔比、温度、停留时间、空气流量、固硫剂粒径及型煤粒重等因素对固硫率的影响，并研制出了高效固硫型煤．

The huge coal combustion has resulted in the serious pollution of SO2 emission and acid rain. Sulfur retention briquette can reduce the pollution of SO2, improve the quality of air environment. Briquette is a simple and economical technique. In this paper, influence factors on sulfur retention of briquette have been studied such as type of sulfur retention agent, Ca/S molar ratio, combustion temperature, retention time, flow of air, particle size of sulfur retention agent and weight of per briquette. High efficient sulfur retention briquettes have been also developed.
