由于火区高温的影响,常规的方法皆不能准确地判定火灾瓦斯的爆炸危险性。本文根据实验室进行的各种温度爆炸试验,将环境高温的影响因素引入到本方法内,从而确立了用不同温度下的爆炸三角形判定火灾瓦斯爆炸危险的方法。使用本方法除可判定瞬时爆炸危险性外,还能预测出其发展趋势,计算出火区所需的惰化量。 Due to the influence of hot zone temperature, conventional methods can not accurately determine the explosion risk of fire gas. In this paper, according to various temperature explosion tests carried out in the laboratory, the influencing factors of environmental high temperature are introduced into this method, so as to establish the method of determining the danger of gas explosion with explosion triangles at different temperatures. In addition to the use of this method can determine the instantaneous explosion risk, but also predict its development trend, calculate the required inerting volume of the fire area.
