1988年全国发电用煤2.24亿吨,燃煤电厂烟囱释放的气载流出物是大气环境主要的污染源之一。其中所含天然放射性核素对附近居民产生附加照射。本工作调查研究了1988年度国内装机容量为2.5万kW以上的255个燃煤电厂的基础数据(包括发电量、用煤量、煤的来源及种类、煤中天然放射性核素的含量、飞灰量 In 1988, 224 million tons of coal were used for power generation in the country. The airborne emissions released from the chimneys of coal-fired power plants were one of the major pollution sources in the atmospheric environment. The natural radionuclides contained therein have additional exposure to nearby residents. This work investigates and studies the basic data of 255 coal-fired power plants with domestic installed capacity of 25,000 kW or above in 1988 (including power generation, coal consumption, sources and types of coal, natural radionuclides in coal, fly ash the amount
