摘要： PURPOSE:To simplify the char recycle system and efficiently conduct blending of char with pulverized coal, by blending char as collected while maintaining the pressurized state with pulverized coal fed into a gasification oven via a pulverized coal metering hopper. CONSTITUTION:Pulverized coal is stored in storage bins 5, 6 and fed into an oven 1 through bins 13, 14 via pulverized coal metering hoppers 9, 10. In the oven 1, a portion of the coal is burnt, while the remaining portion is gasified, thereby forming a gas and char. These are discharged from the oven 1, and separated by means of a cyclone 17 provide in a chimny 16. The char is collected in the cyclone, and the gas is discharged towards the rear flow side. The collected char is accumulated in a dust-collecting hopper 18 while maintaining the back pressure of the oven 1 and fed into a char lock hopper 19 via a lock valve. If necessary, a pressure is applied, and the char is fed into a metering hopper 10. In this hopper 10, the char is blended with pulverized coal. The blend is fed into the oven 1 through a coal feeder 12 and a pulverized coal carry line 14, where it is burnt.

摘要： PURPOSE:To reduce the content of NH3 and HCN in a gas formed in a spouted bed coal gasifying oven, by feeding a coal containing a larger amount of nitrogen into a combustor in a larger amount to reduce the content of NH3 and HCN in a formed gas. CONSTITUTION:In a reactor 3, a pulverized coal injected from an injection nozzle 4 is gasified by heat of combustion of a combustor 2 to obtain a formed gas composed mainly of hydrogen, carbon monoxide, etc. The formed gas ascends to the upper part of the reactor 3 and discharged via a discharging line 6. An unreacted char which has ascended to the upper part of the reactor 3 together with the formed gas is fed via a char recovering line 7 into the combustor 2 to burn it with a main fuel (pulverized coal). In the present apparatus, most of NH3 and HCN contained in the formed gas is employed for nitrogen in the coal, the amount of NH3 and HCN formed is small because of high- temp. atmosphere and a high air ratio and the remainder is converted into harmless N2.

摘要： PURPOSE:To prevent an inside furnace temperature from decreasing as well as to prevent slags stream at its discharging exit port from clogging by a method wherein an ash hopper and a combustion furnace are connected with a return-tube path of combustion gas through an ari-blower, further the return tube path is equipped with a branch line, the second return tube path, which is connected newly to a upper side of the combustion furnace. CONSTITUTION:The combustion gas taking out from the ash hopper 2 is structurally returned to the inside furnace 1 by the use of air blower 21 through the return-tube path 23, and in the return-tube path a high pressure gas flow-meter 22 is provided. In discharging melted slags, which are produced in the furnace 1 due to a high temperature burning, from a slag discharging exit port 17, the both gas and slags are taking out simaltaneously aiming at maintaining smooth fluidity andquantatively discharge of the slags. By returning the combustion gas into the furnace 1, the decrease in temperature inside of the furnace is prevented. Since the taking out gas are wholly returned to the furnace 1, its thermal efficiency is improved. Besides, no impacts is given to the burning condition of the furnace with a withdrawal of the combustion gas, therefore, combustion is stabilized, further a large amount gas are in controllable condition, therefore, it is made possible to maintain better fluidity of slags as well as to incrase quantative discharge of glags.

摘要： PURPOSE:To enable to control steady discharge of melted slag, by controlling combustion in a furnace by monitoring the absorption of refractory wall which is composed of built-in water cooling pipes, constituting the furnace. CONSTITUTION:The combustion in a furnace is controlled by monitoring a value determined by multiplying the amount of feed cooling water by the differ ence of temperature in cooling water at the inlet and the outlet of a furnace. When the temperature in gas in the furnace is decreased and the thickness of a slag layer 6 in the furnace wall 2 is increased, the heat resistance between water cooling pipes 4 and the inside of a furnace grows large, and the heat absorption of water cooling pipes 4 is decreased. The heat absorption of water cooling pipes 4 is constant when combustion is taken place normally in the furnace and driping of melted slag is normal and in specified thickness. By the above-mentioned method, the state in the whole furnace can be monitored n comparison with partial monitoring in temperature, and it enables proper combustion control in accordance with the fluidizing point of ashes by the kind of fuel coal, not subjected to the effect of a slag layer 6 in the furnace wall.

摘要： PURPOSE:To enhance chatching efficiency for char and to gasify it with an excellent gasification efficiency, by catching the char in product gas by a wet scrubber and supplying it again to a gasification kiln in slurry. CONSTITUTION:Pulverized coal stored in a pulverized coal hopper 11 is sent by air via a pulverized coal feeder 12 to a gasification kiln, where a portion is burned and the other portion is gasified to obtain product gas contg. char. Then the gas is introduced into a wet scrubber 14 and washed with water supplied from a washing water recycling pump 15, to catch the char in the product gas. The char slurried in the washing water is periodically discharged from the bottom of the scrubber 14 via a lock valve 16 to a char-water slurry hopper 17, and the char- water slurry is supplied again for the gasification kiln by a slurry supply pump 18.

摘要： PURPOSE:To positively discharge molten slag from a combustion furnace by quenching and crushing the molten slag flowing down out of the opening part of the furnace bottom. CONSTITUTION:When a molten slag 9 produced within an combustion furnace 1 falls through a slag discharge hole wall 5, cooling water 25 is ejected through a cooling water nozzle hole 23 of a cooling water conduit 22, toward a falling molten slag 10. Since the falling molten slag 10 is quenched by the cooling water 25, the slag 10 causes quench-crushing, and assuming a form of a crushed slag 26 of small mass and falling down into an ash holler 3. By utilizing such a phenomenon that when the molten slag of high temperature is quenched by cooling water in the above described manner, the slag is crushed, the molten slag flowing out of the slag discharge hole 6 of the combustion furnace 1 is quenched and crushed. Accordingly, the molten slag is prevented from accumulating and growing as a slag mass, and hence there is no possibility of the slag discharge hole being blocked.

摘要： PURPOSE:To stably feed a mixture of char and air to a gasifier, by slurrying char collected from formed gas in the drain of the formed gas and feeding the slurried char to the gasifier. CONSTITUTION:Gas from a gasifier 3 is passed through a char collector 4 to remove char, and the resulting gas is fed through a gas line 14 to a gas cooler 15 to cool it. Hence, moisture in the formed gas is condensed to form drain, and the drain is fed through a drain line 17 to a slurry vessel 18. The char collected by the collector 4 is stored in a char hopper 15, and a predetermined quantity of the char is peridically fed to the slurry vessel 18 by the opening and closing of a lock valve 6. Accordingly, the char in the vessel 18 is mixed with drain discharged from the gas cooler 15 to form a slurry. The char/water slurry is fed through a slurry line 20 to the gasifier 3 by means of a slurry pump 19 to re- burn the char.
