煤矿建设矸石电站技术可行、经济合理,它能提高煤炭资源的综合利用率;改善环境;少占农田。这些已被人们所确认。我国在“七五”期间,计划发展45座矸石电站。这些电站建成后,每年可发电55亿度,节约原煤三百万吨,创利1.4亿万元。 1983年鉴定通过的35吨/时的SFH35—39/450型电站沸腾炉,是新型的电站锅炉。由于其燃烧低发热值燃料,燃烧温度低,其热效率只达71％,与其它同级电站锅炉相比显得低
Coal mine waste rock power station construction technology is feasible and economical, it can improve the comprehensive utilization of coal resources; improve the environment; less accounting for farmland. These have been confirmed by people. During the “Seventh Five-Year Plan”, China plans to develop 45 gangue power plants. After the completion of these power plants, they can generate 5.5 billion kWh annually, saving 3 million tons of raw coal and earning a profit of 140 million yuan. The 35 ton / hour SFH35-39 / 450 Power Station Boiler, appraised in 1983, is a new type of utility boiler. Because of its combustion of low calorific value fuel, the combustion temperature is low, the thermal efficiency of only 71%, compared with other similar low-grade power plant boilers
