论述了燃气锅炉发生“点火爆炸”和“熄火爆炸”的原因,基本上都是由于燃气锅炉供气系统中的快速切断阀关闭不及时,使进入炉膛的燃气达到爆炸极限造成的。通过推导公式计算快速切断阀的允许切断时间,并总结燃气锅炉供气系统中快速切断阀的选择方法。
The reason why gas boilers occur “ignition explosion” and “flameout explosion” is basically due to the short cut-off valve in the gas supply system of the gas boiler is not closed in time so that the gas entering the hearth reaches the explosion limit . Calculate the allowable shut-off time of the quick shut-off valve by deriving the formulas and summarize the selection method of quick shut-off valve in the gas supply system of the gas boiler.
