我厂二分厂生产锻材,有三吨和一吨蒸汽锤各一座,原有三台仿苏K-4锅炉,人工加煤,劳动强度大,工作环境差,各项技术指标落后,排烟温度高达450℃,热效率为50％,每台锅炉每小时产汽量只有3吨。为了满足生产上需要,每天必须烧二台锅炉,耗煤30吨。为了降低煤耗,改善劳动条件,我们对这种锅炉进行了技术改造,收到了较好的效果,现将1~#K-4锅炉的改造情况介绍如下: 一、技术改造措施 三、改善燃烧条件 (1)将原来的手烧炉改为链带式链条炉排。
The second branch of our factory produces forging material, one for each of three tons and one ton of steam hammers. The original three imitation Su-K-4 boilers are man-made with coal. The labor intensity is large and the working environment is poor. The technical indicators are lagging behind and the exhaust gas temperature is up to 450 ℃, the thermal efficiency of 50%, each boiler steam volume per hour only 3 tons. In order to meet the needs of production, two boilers must be burned every day, consuming 30 tons of coal. In order to reduce coal consumption, improve working conditions, we have carried out technical transformation of this boiler, received good results, now 1 ~ # K-4 boiler transformation introduced as follows: First, the technical transformation measures Third, to improve combustion conditions (1) The original hand furnace into a chain-type chain grate.
