四、事故原因

直接原因类别: 未遵守现有程序（违章，无程序，不理解等）

直接原因: 公司停电后，机修工唐XX未严格按照锅炉的《供热系统工艺流程图》及《产品说明书》的内容，进行冷油置换及导热油锅炉的紧急停炉处理，未将炉膛内燃煤排出，未停止鼓风及引风，使锅炉内温度持续上升，导热油气化，气化的导热油通过膨胀管时，不能平衡系统内的压力，致使膨胀管剧烈振动，与管道支架发生碰撞、摩擦，产生大量火花。管道断裂后，锅炉膨胀槽内溢出的油气遇到油气分离器上喷出的火苗后被点燃，从膨胀槽上方的通气管发生回火，点燃膨胀槽罐体内部油气，由于油气处于相对较封闭的罐内，进而造成高压爆炸现象。

根本原因类别: 操作规程或程序不足
