我厂锻造车间的反射炉窑是耗能较大的设备之一，按国家有关规定，该反射炉窑每吨合格锻件耗煤应为１吨，但改造前耗煤高达１．６吨，大大超过国家标准。为了节能增效，降低成本，对该炉窑进行了技术改造。 改造前，我们对该炉进行了考查。发现其结构方式不合理，主要是（１）燃 Reflecting kilns in our forging workshop are one of the most energy-intensive equipment. According to the relevant regulations of the state, the coal consumption per ton of qualified forging for this refiring kiln should be 1 ton, but the coal consumption before the transformation is as high as 1.6 tons, More than the national standard. In order to save energy and increase efficiency, reduce costs, the kiln has been technically transformed. Before retrofitting, we examined the furnace. Found that its structure is unreasonable, mainly (1) burning
