摘要： PURPOSE:To permit a high-performance operation of the gasification of solid carbonaceous substances, producing a gross high calorie gas, by the system in which a gas containing CO2 and H2O, e.g., the waste gas from a hot blast stove, a lime kiln, etc., is used as a carrier gas for coal and also the waste gas is utilized for the control of the temperature of an iron bath. CONSTITUTION:The waste gas from a hot blast stove, a heating furnace, a lime kiln, etc., containing CO2 and H2O, is used as a carrier gas for coal and also the waste gas is utilized to control the temperature of an iron bath, in which the waste gas is reformed into a combustible gas by the reactions of the formulas I and II and at the same time the temperature control of the iron bath is made possible. As shown in Fig. when coal is delivered by the waste gas as a carrier gas and blown with O2 into the iron bath 2 through the blowing lance 4, the coal is soon converted into CO and H2 gases by the reactions of the formulas I and II, and then the combustible gases are recovered through the duct 5 and stored in a gas holder through a clarifier. In case where the temperature of the waste gas is high, water is supplied for regulating the temperature of the waste gas by the latent heat of evaporation of water and thereby the temperature of the iron bath can be controlled.

摘要： PURPOSE:To form the layers of solidified iron and solidified slag to even thicknesses on the inside surface of the spout and prevent the consumption of the stamp material of the spout inside surface of providing a water cooling unit to the outside surface of the spout of the blast furnace, controlling a cooling water valve by the inlet and exit side temperatures of the molten iron and cooling water and adequately controlling the temperature of the top surface of the spout. CONSTITUTION:The casting bed spout or tapping spout 3 of the blast furnace is formed by stamping stamp material 2 of a fixed thickness on the inner side of a carbon spout 1 and a cooling water channel 4 is provided on the outer side thereof. A valve 13, cooling water temperature detector 8 and water amount detector 7 are provided to the inlet side pipe 6 of cooling water and an exit side temperature detector 10 is provided in the exit side pipe 9. Further, a temperature detector 11 of molten iron and molten slag is provided in the spout 3. The information from the respective detectors 7, 8, 10, 11 is inputted to an arithmetic unit 12 which in turn emits a signal to the valve 13 so that the temperature of the contact surface between the spout 3 and the molten iron or molten slag becomes less than the solidification temperature of the molten iron or molten slag, whereby the opening of the valve 13 is controlled. The surface temperature of the stamp material 2 of the spout 3 becomes lower than the solidification temperature of the molten iron or molten slag and the solidification layer of the molten iron or molten slag of an even thickness is formed on the inside surface of the stamp material 2, whereby the damaging of the stamp material 2 is prevented.
