五、其它 1.高炉炉顶压差发电设备 1981年11月19日,首都钢铁公司与日本日立造船进行补偿贸易,日方提供高炉炉顶压差发电成套设备(即TRT装置),它是利用高炉炉顶煤气的压力能转换成电能,包括高炉炉顶压力回收透平、发电机、润滑油设备、TRT装置大型阀门、自动调节仪表控制系统等,装机容量5000kW,合同总价为247万美元。建成后,不用耗煤,每年可发电3500万kW·h,年获利224万元,约运行三年,即可全部收回投资。
V. Others 1. Blast Furnace Top Pressure Difference Power Generation Equipment On November 19, 1981, Capital Steel Co., Ltd. and Japan’s Hitachi Shipbuilding Co., Ltd. compensated the trade. Japan provided blast top pressure difference power generation complete sets of equipment (ie, TRT unit) Blast furnace top gas pressure can be converted into electrical energy, including blast furnace top pressure recovery turbine, generator, lubricating oil equipment, TRT device large valves, automatic control instrument control system, installed capacity of 5000kW, the contract total price of 247 million US dollars . After the completion of the project, it will save 35 million kW · h of electricity and consume 2.24 million yuan annually without coal consumption. After three years of operation, all investments can be recovered.
