某矿由于煉锡鼓风爐发生爆炸事故,严重地影响生产任务的完成。为了使各地冶煉厂能够从这一次事故中,吸取教训,特将事故加以分析和介绍于下,希望引起有关部门注意,提高警惕。某厂是用木炭作还原剂,经常配入木炭量为矿石量80％左右,在开爐时或中途短时间停爐后再去开爐时,则配入木炭量要多些。由于开爐温度不高,此温度不高的时间维持过长,所以使煤气大量产生,煤气中含一氧化碳很高,大约在25％左右。加之在操作技术规程方面也未留意,而使加料口处冒出明火,明火中的火星被气流带进沉淀烟尘室和烟道室中,以致引起爆炸事故。现从五方面来分析当时爆炸产生的原因。
A mine explosion due to smelting tin blast furnace, a serious impact on the completion of production tasks. In order to enable local smelters to learn lessons from this accident, especially to analyze and introduce the accident in the next, hoping to draw the attention of relevant departments and vigilance. A factory is to use charcoal as reductant, often with charcoal amount of about 80% of the ore, open the furnace or open a furnace shortly after the shutdown time, the amount of charcoal allocated to more. As the furnace temperature is not high, the temperature is not high for a long time to maintain, so a lot of gas to produce gas containing high levels of carbon monoxide, about 25%. In addition to the technical aspects of the operation did not pay attention, leaving the mouth of the mouth of the open flame, the fire in the spark was brought into the precipitation dust chamber and the flue chamber, resulting in an explosion accident. Now from five aspects to analyze the cause of the explosion.
