我厂2号炉系上海锅炉厂五十年代生产的ДКВ10—13型抛煤机锅炉。一九七九年改装成链条炉,每小时蒸发量15吨,工作压力为13公斤/厘米~2。实现了仪表集中和远距离控制,提高了热效率和机械化程度。运行性能参数如下:平均汽压 10.6公斤/厘米~2平均蒸发量 9.5吨/小时出预热器热风温度 185度烟温:炉膛出口 1060度排烟 209度渣中含碳量 12.8％锅炉热效率 78.964％改装前,我们进行了必要的热力计算,据此确定了总体改装方案,并做了较完整的改装设计。现将改装中的几个主要问题介绍
I plant No. 2 Department of Shanghai Boiler Factory in the fifties production ДКВ 10-13-type boilers. In 1979, it was converted into a chain furnace with an evaporation of 15 tons per hour and a working pressure of 13 kg / cm ~ 2. Achieved instrument concentration and long-distance control, improve the thermal efficiency and mechanization. Operating performance parameters are as follows: Average steam pressure 10.6 kg / cm ~ 2 The average evaporation 9.5 tons / hour out of the preheater hot air temperature of 185 degrees Smoke temperature: furnace exhaust 1060 degrees exhaust 209 degrees C 12.8% of the boiler thermal efficiency of 78.964 Before the modification, we carried out the necessary thermodynamic calculation, thus determined the overall conversion program, and made a more complete conversion design. Now the modification of several major issues introduced
