一、研究目的北京城近郊区燃煤锅炉共有17000台左右,其中蒸发量为20吨/时以下的工业锅炉、取暖锅炉约一万台,饮水茶炉约七千台。每年消耗煤量达400多万吨,排入大气中烟尘20多万吨,严重污染了首都的环境。为了改善大气质量,近几年来,对燃煤锅炉采取改进燃烧方式和加装除尘器等方法,取得了一定效果。1979年10月我们对北京市使用的九种旋风除尘器进行了热态运行的研究与评价,同时对北京市大量存在的不同容量、不同燃
First, the purpose of the study Beijing suburbs coal-fired boilers a total of about 17000, of which the evaporation of 20 tons / h below the industrial boilers, heating boilers about 10,000 units, drinking water stoves about 7000 units. Annual consumption of coal amounted to more than 400 million tons, more than 200,000 tons of dust discharged into the atmosphere, seriously polluting the capital’s environment. In order to improve the air quality, in recent years, the coal-fired boilers to improve combustion methods and installation of dust remover and other methods, and achieved some results. In October 1979, we conducted a study and evaluation on the hot operation of nine cyclone dust collectors used in Beijing. At the same time, we studied the existence of a large number of different capacity,
