摘要：

Studies were made of the changes in heat loss that occur during the operation of a blast furnace with pulverized-coal fuel (PCF). It is shown that the use of PCF increases heat losses relative to the furnace's heating capacity. These losses increase from 1.15% without PCF use and an intact lining to 3.7% with maximal lining wear and the use of PCF at a rate of 187 kg/ton pig iron. Minus the chemical heat of the top gas, the heat losses incurred relative to the heating power of the furnace increase from 2.78 to 8.81%.
