氨气是一种易燃易爆气体。它与空气混合达到爆炸极限时,遇到火源就会发生爆炸和着火。因此,有的同志在对氨气场所(如氮肥厂的合成车间、冷冻厂的氨压缩机房)进行防火检查时,看到有的电气没备不是防爆类型的,就认为是火险隐患,要求单位改成防爆电气设备。对此,笔者不敢苟间。 Ammonia is a flammable and explosive gas. When it mixes with air to reach the explosion limit, it explodes and ignites when it encounters a source of ignition. Therefore, some comrades in the ammonia sites (such as the nitrogenous fertilizer plant synthesis workshop, refrigeration plant ammonia compressor room) for fire inspection, to see some of the electrical equipment is not explosion-proof type, it is considered to be a fire hazard, requiring units Into explosion-proof electrical equipment. In this regard, I can not agree.
