冶金工业部《88冶能字第083号》文件中关于“加热炉燃耗等级计算方法”的公式为: 加热炉实际单耗=燃料消耗量/入炉原料量 [公斤标煤/吨(坯)锭] ……(1) 加热炉可比单耗=加热炉实际单耗/1+(?)(K_i—1) [公斤标煤/吨(坯)锭] ……(2)式中: 燃料消耗量—包括烘炉、升温、待轧、保温、空烧、亏损消耗的燃料。 Ministry of Metallurgical Industry “88 Ye can word word No. 083” file on the “heating furnace fuel consumption level calculation method,” the formula is: actual consumption of heating furnace = fuel consumption / raw materials into the furnace [kg of standard coal / ton ) Ingot] (1) The unit consumption of heating furnace is equivalent to the actual unit consumption of heating furnace / 1 + (?) (K_i-1) [kilogram of standard coal / ton Consumption - including ovens, heating, to be rolled, heat preservation, empty burning, loss of fuel consumption.
