摘    要:研究了一种高温低氧燃烧新技术,即采用蓄热室,预热助燃剂使其温度达到800℃以上;采用分级燃烧及炉内部分烟气回流的方法,使燃烧区氧体积分数降低至15%以下.分析结果表明该燃烧技术具有显著的节能、低污染特性,与未采取任何废热回收措施的传统燃烧技术相比,可实现节能60%以上,CO2排放量减少60%以上,NOx排放浓度低于30~50g/t.

关 键 词:节能;污染;高温低氧燃烧技术;蓄热式烧嘴

Abstract:The high temperature air combustion technology is introduced in this paper. The air is preheated over 800℃by regenerator and oxygen concentration is decreased to less than 15% by graded combustion and a part of exhaust gas isrecycled in furnace. Analyses show that, the technology can save energy efficiently up to 60% and reduce pollution. Forexample, the discharge of CO2 can be reduced by 60%, and the discharging concentration of NOx is less than 30~50 g/t compared with traditional combustion technology without provision of any waste heat recovery means.
Keywords:energy saving  pollution  high temperature air combustion  regenerative burner
