随着经济的快速发展,对环境污染实行治理的要求愈来愈迫切,在我国大气污染的主要来源是燃煤。国际上已公认,流化床燃煤脱硫是解决大气污染的重要方法之一,也是最廉价高效的脱硫方法。自六十年代开始,截止一九八八年底,我国运行的流化床锅炉已达到2000多台,全部属于鼓泡床锅炉,这种锅炉存在着热效率低,飞灰量大,大气污染严重等缺点。随着国外第二代流化床锅炉——循环床锅炉的出现,将该技术推向了高效低污染的新水平,
With the rapid economic development, more and more urgent demands are put on the control of environmental pollution. The main source of air pollution in our country is coal combustion. Internationally recognized, fluidized bed coal desulfurization is one of the important ways to solve the air pollution, but also the most cheap and efficient desulfurization methods. Since the 1960s, as of the end of 1988, more than 2,000 fluidized bed boilers have been operating in our country, all of which are bubbling-bed boilers. Such boilers have such problems as low thermal efficiency, large amount of fly ash and serious air pollution Disadvantages. With the advent of the second generation of fluidized bed boilers - circulating bed boilers in foreign countries, this technology has been pushed to a new level of high efficiency and low pollution,
