摘要： PURPOSE: To prevent the occurrence of a slagging trouble in a coal fired boiler and reduce unburned combustibles in ash contents and thereby enhance plant efficiency. CONSTITUTION: A plurality of preliminary combustion chambers (slagging combustors) 9 are installed outside a boiler furnace (main combustion chamber) 12 so as to perform the combustion reduction of crushed fine coals at a very high temperature by way of an oxygen-enriched secondary air. The fly ashes collected air recycled to the preliminary combustion chambers 9 so that they may be burned. This construction makes it possible to burn unburned combustibles completely and turn every noncombustible to molten slag, thereby discharging the slag to a slag hopper 10.

摘要： PURPOSE:To provide a method for operating a two-stage entrained bed gasification furnace capable of promoting the trap and discharge of molten slag in a combustor and promoting gasification in a reductor. CONSTITUTION:The lower part of a gasification furnace 1 is served as a combustor where pulverized coal fed from a combustor burner 3 is burned and a high- temperature combustion gas is produced. The upper part of the combustor is served as a reductor where highly pulverized coal fed from a reductor burner 4 is gasified. The pulverized coal is fed from a coal-pulverizing mill 16 to the combustor burner 3. The highly pulverized coal is fed from a mill 19 for highly pulverizing coal to the reductor burner 4. As described above, by feeding two kinds of pulverized coal differing in particle size range from each other into the burners 3 and 4, the trap and discharge of molten slag in the combustor and the gasification in the reductor are both promoted.
