一、压差发电我厂压差发电(余热发电)于81年9月试车运行,装机容量3台共4500KW。其中两台是广州机组,一台是杭州机组。因机组排汽压力原设计为3～5atm,而我厂生产用汽压为7～8atm为了满足生产用汽压力,已将广州两台机组的蒸汽喷嘴改为叶片喷嘴,从而增加了通流面积,由原2540mm~2增至3830mm~2,提高背压至7～8atm后,实际发电量每台最高只达1200KW。自82年
First, the differential pressure power generation plant differential pressure power generation (waste heat power generation) in September 81 trial run, installed capacity of 3 units total 4500KW. Two of them are Guangzhou units and one is Hangzhou units. Exhaust pressure of the original design for the unit 3 ~ 5atm, and I plant production with steam pressure of 7 ~ 8atm In order to meet the production pressure of steam, the two units in Guangzhou have been replaced by steam nozzle vane nozzle, thereby increasing the flow area , From the original 2540mm ~ 2 to 3830mm ~ 2, increased back pressure to 7 ~ 8atm, the actual generating capacity of only up to 1200KW each. Since 82 years
