摘　　要：电站锅炉炉膛爆炸是火力发电厂事故中比较严重的事故之一。论述了电站锅炉因煤粉等燃料的爆燃、水冷壁爆管、过热器爆管、再热器爆管、炉底析铁氢爆等导致炉膛破坏的原因,并针对不同的爆炸原因,分别提出了相应的预防炉膛爆炸措施。Explosion accidents of boiler furnace occur frequently in thermal power plant. This paper analyzes the reasons that result in explosion in the furnace because of coal powder＇s deflagration and the destruction of the furnace because of water-wall tube＇s bursting, and the decrepitating of separated iron＇s hydrogen. Preventing measures are respectively proposed to avoiding boiler furnace explosion according to these reasons.
