法国索尔梅公司福斯厂有两座日产生铁能力各为6000吨的高炉,每座高炉有三座地得式外燃热风炉(加热面积为58000米~2),拱顶最高温度1550℃,风温稳定在1250℃(混冷风调节),燃料为混合煤气(高炉煤气、焦炉煤气和转炉煤气)。热风炉上安装了两套设备相同的以水为热媒体的换热器来预热助燃空气和高炉煤气,并已投产。余热回收装置工艺流程见图1。
France Solmet Fox Factory has two production capacity of 6,000 tons of iron each blast furnace, blast furnace each have three ground-type external combustion stove (heating area of 58,000 m ~ 2), the highest dome temperature 1550 ℃ , Air temperature is stable at 1250 ℃ (mixed air conditioning), the fuel for the mixed gas (blast furnace gas, coke oven gas and converter gas). Hot air stove installed two sets of the same equipment with water as the heat exchanger media to preheat combustion air and blast furnace gas, and has been put into operation. Waste heat recovery plant process shown in Figure 1.
