0引言随着我国经济的不断发展,水泥工业技术的不断进步,节能环保对水泥窑系统的要求也越来越高。近几年来,水泥窑系统大部分增加了脱硫、脱硝装置,使整个熟料煅烧过程发生的各种物理化学变化更加复杂化。在预热器、分解炉、回转窑整个系统发生预热、分解、固相反应、熟料烧成等反应,伴随着熟料烧成反应的同时,也发生煤炭燃烧、脱硫、脱硝等复杂的反应过程,产生各种爆炸性气体,对这些气体如果分析不透,控制不当,在系统内达到爆炸极限,
0 Introduction As China’s economy continues to develop, the continuous improvement of cement industry technology, energy-saving environmental requirements for cement kiln system is also getting higher and higher. In recent years, most of the cement kiln systems have been equipped with desulfurization and denitrification devices, further complicating various physicochemical changes in the whole clinker calcination process. In the preheater, calciner, rotary kiln the entire system preheating, decomposition, solid-phase reaction, clinker firing and other reactions, along with the clinker firing reaction, but also occurred in coal combustion, desulfurization, denitrification and other complex Reaction process, resulting in a variety of explosive gases, these gases if the analysis is not transparent, improper control, explosion in the system to reach the limit,
