3200m^3高炉喷煤系统技术特点

Technical Feature of Coal Injection System in 3200 m^3 BF

新区3 200 m3高炉喷煤系统采用中速磨负压制粉,一级高浓度低压脉冲长袋式收粉器收粉。喷吹系统采用双系列双罐并列单管路加分配器浓相输送工艺。喷煤系统按烟煤和无烟煤混喷设计,制粉系统按强爆炸性烟煤设计,最大喷煤比250 kg/t,尾气排放煤粉质量浓度≤30 mg/m3,喷煤系统投运后,运行正常,烟煤配比达40%,高炉喷吹效果良好。

New3 200 m3 BF coal injection system uses negative pressure in the grinding speed milling,a high concentration of low-voltage pulse length pink bag closing device received powder.Double-injection system uses a double series of parallel single-line Canadian distributor tank dense phase conveying technology.Bituminous coal and anthracite coal injection system mixed by spraying the design,bituminous coal pulverizing system design by strong explosive,the largest coal injection than 250 kg/t,emissions pulverized coal concentration ≤30 mg/m3,pulverized coal injection system put into operation,operating normally,bituminous coal with Than 40%,blast furnace injection good effect.
