摘要
传统的火焰燃气炉往往会产生不同数量的氮氧化物(NO和NO2)、一氧化碳等不完全燃烧产物,造成了环境污染和能源浪费。催化燃烧作为一种新的燃烧方式,打破了传统火焰燃烧的可燃界限,实现了贫甲烷/空气混合物在可燃界限以下的燃烧,燃烧效率高,提高了能源利用率。将催化燃烧应用于燃气炉,可以解决燃气炉由于火焰燃烧带来的燃烧效率低等缺点,达到节约能源的目的。以催化燃烧和燃气炉为依据,在催化燃烧炉Ⅰ型的基础上研制出催化燃烧炉Ⅱ型,分析了催化燃烧炉的热损失以及热效率,并与传统火焰燃烧炉做了比较。结果表明,催化燃烧炉Ⅱ型的热损失并不大,热效率较高,且其污染物排放量极低。
The gas boilers of conventional flame always produce varying degrees of combustion products NOx and CO, which make the environmental pollution and energy waste. As a new way of combustion, catalytic combustion breaks the flammable limits of conventional flame combustion, and realizes the combustion of ultra-natural gas/air mixture under the flammable limits. Its combustion efficiency is higher, which can improve the ratio of energy utilization. The way of applying the catalytic combustion to gas boilers could solve the gas boilers＇ lower combustion efficiency, and achieve the purpose of energy-saving. On the basis of catalytic combustion burner Ⅰ , the catalytic combustion burner Ⅱ was designed according to the catalytic combustion and water heaters. The heat loss and thermal efficiency of catalytic combustion burner Ⅱ were analyzed and compared with that of flame combustion boilers. The results show that catalytic combustion burner II＇s heat loss is not so high as considered, and its pollutant emissions are lower.
