我厂80万 t/a 渣油催化裂化能量回收机组是由兰炼机械厂生产的烟气轮机、西德 GHH公司生产的轴流风机和背压汽轮机及瑞典 ASEA 公司生产的异步电动/发电机组成的同轴四机组。其中烟气轮机是兰炼机械厂生产的第一台10000kW 双级大功率烟机。机组自1689年5月19日投入运行至1992年4月25日已安全运行22467 h,按每小时回收功率6000kW 计算,累计节电13480万度,以电价0.25元/度计算,累计经济效益约3370万元。1 转子使用情况良好YLⅡ—10000A 型烟机转子在结构、选材和涂层等方面较 YLⅡ—6000型烟机均有较大改进。轮盘材料为 Waspaloy(相当干国产GH864),叶片材料为 GH864,主轴材料为AISI 4340,叶片涂层材料为“长城1号”,止推
Our 800,000 t / a residue catalytic cracking energy recovery unit is produced by Lan Lian Machinery Factory flue gas turbines, West Germany GHH production of axial fans and back pressure turbines and ASEA Swedish company produced asynchronous motor / generator Composed of four coaxial units. One of the flue gas turbine is Lan Lian Machinery Factory production of the first 10000kW two-stage high-power hood. The unit was put into operation from May 19, 1689 to April 24, 1992, and it has been operated safely for 22467 h. Calculated on the basis of the recovered power of 6000 kW per hour, the accumulative power-saving has reached 134.8 million kWh and the electricity price has reached 0.25 yuan / kWh. 33.7 million yuan. A rotor is in good condition YL Ⅱ-10000A smoke machine rotor in the structure, material selection and coating, etc. than the YL Ⅱ-6000-type hood have greatly improved. The material for the roulette wheel is Waspaloy (equivalent to GH864 made in China), the GH864 is the blade material, the AISI 4340 is the main shaft material, and the Great Wall 1 is the coating material for the blade.
