摘要： PURPOSE:To obtain molten iron and fuel gas economically, by blowing pulverized coal into a molten iron bath placed in a vertical furnace to form the swirling ascending flow of a reducing gas and bringing said gas flow into counter current contact with the descending flow of powdered iron are and powdered limestone. CONSTITUTION:A pair of lances 7, 7 for introducing pulverized coal and oxygen are provided at the lower part of the side wall of a tubular vertical furnace 3 so that pulverized coal will give a swirling stream and the direction of blow ing will be out of the center of the furnace. Pulverized coal and oxygen are blown through the lances 7, 7 into a molten iron bath 1 placed in the bottom of the furnace 3 to gasify the pulverized coal and form the swirling ascending flow of a reducing gas. Said gas flow is brought into counter current contact with the descending flow of powdered iron ore and powdered limestone. In this way, iron ore is reduced and molten by the reducing gas to form molten iron, and the reducing gas is desulfurized by limestone to obtain fuel gas.

摘要： PURPOSE:To provide titled unit for preventing the refractory material from damage due to scattering of molten iron and slag, by making such a structure as to put molten iron only into the gasifying agent jet-impinging section on molten iron surface and another section necessary for slag discharge and to be winder free space than that for putting said molten iron. CONSTITUTION:A molten iron is charged, through inlet 7, nearly to the level of slag-discharge outlet 10 in furnace 1 followed by blowing pulverized coal, O2 and water vapor through non-immersion porous lances 4a-4c to the molten iron bath; concurrently, submaterial(s) such as slag-adjusting agent being added through inlet 6. The high-temperature gas thus generated in the furnace heats slag 13 during passing through slag-molten iron separating unit 8. During the gasification process, the slag and molten iron violently scatter in all directions, however, hardly reaching furnace wall 2 as the free space is sufficiently wide, thus damaging the refractory material slightly. Along with the gasification process, the outlet 10 is opened, the slag being automatically discharged out of the furnace.

CONSTITUTION:A molten iron bath 23 is introduced into a doughnut-shaped annular gasifying oven 1 through an inlet 6. Coal in fine powder, oxygen and steam are blown into it by means of a lance 4-2 and auxiliary raw materials such as slag conditioner are fed through an auxiliary raw material inlet 5. The molten iron bath 23 and formed slag 24 are allowed to circulate slowly in the doughnut-shaped passageway of the gasifying oven 1 under the agitating action of solenoid pumps 9-1, 9-2 and the formed gas is recovered through a gas discharge opening 7. The amount of slag is monitored continuously with a level sensor and when the amount of the slag 24 is increased, slag discharge orifices 8-1, 8-2 are opened for discharge from the oven.

摘要： 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.
