首钢二号高炉汽化冷却,自1979年12月15日投产以来,进行了一系列的研究和改进。并在煮炉、蒸汽引射、多汽包独立循环系统、热负荷确定、升压操作、监控仪表配套及自动检漏方面取得了一些经验。目前,首钢二号高炉汽化冷却,已成为我国第一个配有整套自动监控仪表(自动补水、自动水位控制、压力自动调节、自动排污、自动检漏)和以汽包分为四个独立循环系统的一段式自然循环汽化冷却系统。并且,经济效益显著,每年平均节水30多万吨,节电200多万度。每吨生铁节约能耗0.955kg标准煤。
Shougang II blast furnace gasification cooling, since December 15, 1979 put into operation, conducted a series of research and improvement. And in the furnace, steam injection, multi-drum independent circulation system, determine the heat load, step-up operation, monitoring instrumentation and automatic leak detection has made some experience. At present, Shougang No.2 blast furnace gasification cooling, has become China’s first with a complete set of automatic monitoring instruments (automatic replenishment, automatic water level control, automatic pressure regulator, automatic sewage, automatic leak detection) and the drum is divided into four independent cycles System of one-stage natural circulation vaporization cooling system. And, significant economic benefits, the average annual saving more than 300,000 tons, saving more than 200 million degrees. Saving energy per ton of pig iron 0.955kg standard coal.
