我国工业炉窑量大面广种类繁多,全国约有11～15万台,其中以煤为燃料的约占70％,且大部分为人工投煤层状燃烧,因此能耗高,对大气环境污染严重。今后我国仍以煤为主要燃料,为了节能与改善大气环境质量,必须对工业炉窑进行治理改造。 There are a large variety of industrial furnaces in China, ranging from 11 to 150,000 units nationwide, of which about 70% are from coal-based fuel, and most of them are anthropogenic coal bed combustion, resulting in high energy consumption and pollution to the air environment serious. In the future, coal will still be the main fuel in our country. In order to save energy and improve the quality of the atmospheric environment, industrial furnaces must be rehabilitated.
