水基热气溶胶灭火剂是以替代哈龙为目的而研制的新一代灭火剂。通过水基热气溶胶灭火剂在燃烧器中燃烧，产生以水蒸气和惰性气体为主体的气溶胶灭火介质，经冷却后，排放到被保护空间，对火灾实施有效扑救。因此，水基热气溶胶灭火剂在燃烧器中的燃烧速度，对其灭火效率有重要影响。研究了硝酸钾、催化剂（caty1）、水分、淀粉等组分含量对水基热气溶胶灭火剂的平均质量燃速的影响规律。

The water aerosol fire-extinguishing agent (WAE) is a new generation of Halon replacement. When the fire is taking .place, WAE will rapidly burn and generate a great deal of inert gas, hot mist and a little amount of particulates. After those combustion product are cooled in the cooling layer, they will be discharged into the ambience and extinguish the fire. So, to WAE, the combustion rate has an important effect on the fire extinguishing efficiency. This article mainly discusses the influence law of WAE's compositions on combustion rate.
