缓燃

缓燃（英语：Deflagration）是火释放能量的两种方式之一^[1]，是以传热方式、低于音速地缓慢燃烧，日常绝大部份火灾皆属缓燃，低于音速的爆炸亦属缓燃。^[1]火另一种释放能量的方式称爆轰，两种方式都有俗称“爆燃”造成混淆。

^ ^1.0 ^1.1 Detonation and Deflagration: What Is The Difference?. Safetell Security, U.K. [2020-06-11]. （原始内容存档于2020-06-11）. DETONATION is a quick and explosive form of fire. [...] DEFLAGRATION is a slow catching fire. Ordinary fire and most explosions are instances of deflagration. Deflagration fires are usually controllable and can be harnessed.[...] Combustion takes different forms. When a decomposition reaction or combination reaction releases a lot of energy in a very short span of time, an explosion may occur. Deflagration and detonation are two ways energy may be released. If the combustion process propagates outward at subsonic speeds, it’s a deflagration. If the explosion moves outward at supersonic speeds, it’s a detonation."
