Also known as smoke explosion, backdraught
A backdraft (North American English), backdraught (British English) or smoke explosion is the abrupt burning of superheated gases in a fire caused when oxygen rapidly enters a hot, oxygen-depleted environment; for example, when a window or door to an enclosed space is opened or broken. Backdrafts are typically seen as a blast of smoke and/or flame out of an opening of a building. Backdrafts present a serious threat to firefighters. There is some debate concerning whether backdrafts should be considered a type of flashover.

回燃（英語：Backdraft），或稱復燃，又稱爆燃，指火災現場在時，因大量的新鮮空氣衝入現場，而導致爆發式的劇烈燃燒現象。例如在燃燒一段時間的房間或飛機裡開窗。與閃燃不同的是，閃燃為火災由濃煙轉向火海的關鍵界定特徵，回燃則是後期的特徵。
