近年来随着我国煤炭供应的日趋紧张和煤炭价格的日愈上涨,以及日渐严格的环保法规的实施,越来越多的企业把目光从传统的燃煤热源转向燃气热源。燃气供热以其环保、节能的显著优势,在全国各地得到了越来越广泛的应用,尤其是热电联产的燃气锅炉备受青睐。然而,实际运行中,由于各种原因会造成燃气管线泄漏,这会造成爆炸事故的发生。一般情况下,这种爆炸事故具有极大摧毁 In recent years, with the increasingly tight coal supply in our country and the rising price of coal, as well as the implementation of increasingly stringent environmental laws and regulations, more and more enterprises turn their attention from the traditional coal-fired heat source to the gas heat source.
