北京重型电机厂有5个锅炉房,锅炉效率较低,进行布局改造后取得了明显效果。东厂锅炉房有五台10t/h 和一台20t/h 蒸汽锅炉,冬季采暖运行一台20t/h 锅炉和2台10t/h 锅炉,最冷天气加开一台10t/h 锅炉,由热交换站加热的热水分别向各分厂车间送暖,蒸汽主要管道最远约两华里,余汽冷凝后由水泵送回软化水罐再用。夏季需运行一台10t/h锅炉供生产生活用汽,10t/h 蒸汽炉为保障用汽月耗煤800t 以上,压火时间较长,为锅炉配套的各电机设备耗能在300kW 以上,实为大马拉小车,人力设备浪费大。为改变上述弊端,1986年2台2t/h 的小锅炉房建成,经过4年的
Beijing Heavy Machinery Plant has five boiler rooms, boiler efficiency is lower, after the layout of the transformation has achieved significant results. Dongfang Boiler Room has five 10t / h and one 20t / h steam boiler, winter heating operation of a 20t / h boiler and two 10t / h boiler, the coldest weather plus a 10t / h boiler, by the heat Heat exchange station hot water to the workshop heating plant, the main steam pipe up to about two years, the condensate after the pump back to the softened water tank reuse. In the summer, a 10t / h boiler is required for the production of household steam, and the 10t / h steam boiler is used for over 800t of coal consumption for steam and steam, and has a longer press-firing time. The energy consumption of each motor supporting the boiler is above 300kW. For the big car, large waste of manpower equipment. In order to change the above shortcomings, two 2t / h small boiler rooms were completed in 1986, after 4 years
