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 80 0℃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 1 5%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.
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 is recycled in furnace. Analyses show that, the technology can save energy efficiently up to 60% and reduce pollution. For example, the discharge of CO 2 can be reduced by 60%, and the discharging concentration of NO x is less than 30～50 g/t compared with traditional combustion technology without provision of any waste heat recovery means.
