    • PURPOSE:To enable coal to be stably supplied economically, by a method wherein steam and a noncondensible gas such as nitrogen are used as carrier gases for coal, and the flow rates of both gases are controlled. CONSTITUTION:Flow rate patterns of steam and nitrogen are preset by a flow rate pattern signal-generating apparatus 34. In the initial stage of transportation, the flow rate of steam is preset at zero in order to prevent the condensation of steam. In the end stage, the flow rate of steam is preset at 100% in order to enhance gasification efficiency. As soon as operation is initiated, the pressure information and the flow rates of steam and nitrogen are input into a flow rate-detecting apparatus 31 by mass flowmeters 35-1, 35-3 and difference pressure converters 36-1, 36-3, whereby amounts flowed into a furnace are calculated. A difference between actual flow rate and the preset flow rate of the flow rate signal-generating apparatus 34, is detected by a flow rate comparator 32, and is output to a valve opening signal-generating apparatus 33. The valve opening-adjusting signals of steam and nitrogen are output to valve opening-controlling apparatus 30-1, 30-3 to to adjust the openings of valves 18-1, 18-3, whereby preset amounts of steam and nitrogen are flowed into the gasification furnace.

    • PURPOSE:Efficient gasification of coal, capable of maintaining carbon concentration in an iron bath and the latent heat of the produced gas, by the gasification of a solid carbonaceous material with addition of Cr, Mo, W, V or Nb to the iron bath, according to the sulfur concentration in the bath. CONSTITUTION:In the gasification of a solid carbonaceous material, in a solid carbonaceous material-gasifying furnace, by means of an iron bath, when the sulfur concentration in the bath increases and the amount of the molten iron in the iron bath is decreased, 30-80kgs, per ton of the molten iron, of at least one among Cr, Mo, W, V and Nb, are added to the ironbath, to maintain the carbon concentration in the bath, and to prevent reduction of coal conversion and of the latent heat of the produced gas. The amount of alloy added to the bath, is so limited as described, because it is impossible to efficiently prevent reduction of the carbon concentration in the bath and maintain the latent heat of the produced gas, by the addition of less than 30kg per ton of the molten iron, and addition of more than 80kgs is ineffective because of saturation, causing a cost increase.

    • 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.

    • 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.

    • PURPOSE:A pressure-releasing valve is installed so that it is opened according to the signals from the pressure detector to maintain the pressure inside the furnace equal to the atmospheric pressure to avoid burst on start and shutdown and prevent the damage of the installation. CONSTITUTION:Melted iron 10 is introduced from the inlet 3 into the gasification furnace and all the valves are closed. Then, the rotor for cut-feeding powdery coal is stopped. The pressure-releasing valve 7 is opened, valves 19-3 is opened to introduced the carrier gas into the furnace. Then, the rotor 22 is started and simultaneously valve 19-1 is opened to introduce oxygen and powdery coal into the furnace to ignite fire. The gas produced is purged through the release valve 7 out of the furnace to burn the flare stack 16 to avoid the gasifier from being damaged. The combustion of the powdery coal in the furnace is detected with a radiation thermometer 17 and the difference in pressure between the inside of the furnace and the outside is detected with the sensor 24 to control the valves 25-1-25-3 to keep the pressure inside the furnace constant.
