一、引言逆向燃烧(简称YR下同)技术,是在简易煤气发生炉基础上建立起来的一种燃烧方式。它与常规的层燃(简称CR下同)技术比较,可节煤10%以上。改2T/h锅炉的CR为YR,钢材消耗量不超过1.5吨,全部改造费用只需0.35万元左右。我们认为YR与CR比较:(一)氧化反应稳定;(二)劳动强度低;(三)环境污染小;(四)节煤效果显著;(五)施工期短,投资省。我们进一步以YR技术产生的高温烟气,经过远红外节能涂料,(简称YT,
I. INTRODUCTION The technology of reverse combustion (abbreviated as YR) is a kind of combustion mode established on the basis of simple gas furnace. It is compared with the conventional layer burning (referred to as CR the same below) technology, saving more than 10%. Change 2T / h boiler CR is YR, steel consumption does not exceed 1.5 tons, all the transformation costs only about 0.35 million. We think YR and CR compare: (1) the oxidation reaction is stable; (2) the labor intensity is low; (3) the environment pollution is small; (4) the coal saving effect is remarkable; We further YR technology to produce high-temperature flue gas, after far-infrared energy-saving coatings, (referred to as YT,
