Abstract

PURPOSE: To improve the rate of heat exchange between the combustion gas and the heat regenerative bricks at the last stage of combustion of the hot stove, by feeding the fuel while keeping the flow rate of the fuel of low calorie constant and increasing the flow rate of the fuel of high calorie at a constant rate with the passage of time.
CONSTITUTION: When the mixed fuel consisting of fuels of more than two kinds is fed to the hot stove for the blast furnace, the flow rate of the fuel of low calorie is kept constant and the fuel of high calorie is fed while increasing its flow rate at a constant rate with the passage of time. With this method, the temperature at the dome rises with the passage of time and the difference of temperature between the combustion gas and the heat regenerative bricks does not lower even at the upper part of the hot stove, so that the rate of heat exchange is improved and the thermal efficiency of the hot stove is enhanced.
