    燃气热风炉之燃烧系统工作原理

    2018-11-26 13:12:02 无锡盛发地坪科技有限公司 阅读

    燃气热风炉是有很多部分组成,燃烧系统是热风炉工作中必不可少成都收账部分,在以后成都找人公司内容中,会介绍更多成都收账燃气热风炉组成部分。高炉煤气由外部接入,分为4路,分别进入热风炉收账4个角(每角4个燃烧喷嘴),参与燃烧;进入热风炉和高炉煤气混合燃烧成都找人公司热风分别进入热风炉的4个角(每角4个燃烧喷嘴),参与燃烧;焦炉煤气由外部接入,分为4路,分别进入热风炉的4个角(每角2个燃烧喷嘴),参与燃烧。正常情况下,燃料为高炉煤气,焦炉煤气只是在点火的时候用到,平时只是作为保安气(作为热风炉燃烧过程中的炉膛温度低时保护气)。

    Gas hot-blast stove is composed of many parts, combustion system is an essential part of the work of hot-blast stove. In the future, more parts of gas hot-blast stove will be introduced. Blast furnace gas is accessed from the outside and divided into four routes, which enter into four corners of the hot blast stove (four burning nozzles per corner) to participate in combustion; hot air entering the mixed combustion of hot blast stove and blast furnace gas enters four corners of the hot blast stove (four burning nozzles per corner) to participate in combustion; coke oven gas is accessed from the outside and divided into four routes to enter respectively. The four corners of the hot blast stove (two burning nozzles per corner) participate in combustion. Normally, the fuel is blast furnace gas, and coke oven gas is used only when igniting, but usually only as security gas (as protection gas when the furnace temperature is low in the combustion process of hot blast stove). 燃烧过程中通过热电偶和火焰观测器来检测炉膛温度变化。通过调节高炉煤气、焦炉煤气、风的配比来调节热风炉炉膛温度(燃料配比一般为100%高炉煤气,另外也有80%——90%高炉煤气加20%——10%焦炉煤气或者50%焦炉煤气)。整个燃烧过程中炉膛温度控制在1100±10℃左右。

    In the combustion process, temperature changes in the furnace are detected by thermocouple and flame observer. By adjusting the ratio of blast furnace gas, coke oven gas and air, the furnace temperature of hot blast stove can be adjusted (the fuel ratio is 100% blast furnace gas, and 80% - 90% blast furnace gas plus 20% - 10% coke oven gas or 50% coke oven gas). During the whole combustion process, the temperature of the furnace is controlled at about 1100 (+10 C).
