采用杨永宜同志的理论焦比工程计算法的基本形式,用高温区域热平衡代替总热平衡,并考虑到各单因素对燃料比的种种影响,导出计算通式,故本通式可以算出在某特定冶炼条件下各单因素对燃料比的综合影响。区域划分温度定为950℃。在>950℃的高温区域热平衡项目有: 收入项:风口区碳素燃烧有效热Q_风 Q_风=C_风×[2340+950℃碳素(焦炭的)物理热+热风带入物理热-鼓风中水份分解热-重油煤粉分解热-炉腹煤气带走热]
Adopting the basic form of Comrade Yang Yongyi’s theory of coke ratio engineering calculation, replacing the total heat balance with the heat balance of the high temperature zone and taking into account the various effects of each single factor on the fuel ratio, the general formula of calculation is deduced, so the formula can be calculated in a specific smelting Under the conditions of the single factor on the fuel ratio of the comprehensive impact. The division temperature is set at 950 ° C. In the high temperature region of> 950 ℃, the heat balance items are as follows: Revenue items: tuyere zone Carbon burning effective heat Q_window Q_wind = C_windowx [2340 + 950 ℃ Carbon (coke) physics Hot + Heat - water in the blast of decomposition of heat - heavy oil decomposition of hot coal - hot belly gas away]
