一、前言我厂锻压分厂的室(双室)式加热炉是70年代初建成投产的。其炉衬:内层是348mm的粘土砖,外层是116mm的硅藻土砖;炉顶内层是232mm的粘土砖,外层是116mm的硅藻土砖。采用引射式烧嘴,烧混合发生煤气,其热值Q_H=5434～5852kJ/m~3。由于炉体结构和烧嘴都是50年代的水平,因此炉子升温慢,炉温偏低,炉内温差大,加热时间长,燃耗高。煤气热值偏低时,炉温
I. Introduction I plant forging factory (double room) furnace is built and put into operation in early 70s. The lining: the inner layer of clay brick is 348mm, the outer layer is 116mm diatomaceous earth brick; roof inner layer is 232mm clay brick, the outer layer is 116mm diatom brick. The use of a burnt-out burner, burning mixed gas occurs, the calorific value of Q_H = 5434 ~ 5852kJ / m ~ 3. As the furnace structure and burner are the level of the 50s, so the furnace temperature is slow, the furnace temperature is low, the furnace temperature, heating a long time, high fuel consumption. Gas heat value is low, the furnace temperature
