Description of Figures Fig 1 is the structure view of this invention, 10 Specific Method for Implementation As shown in Fig 1, a pulverized-coal gasification furnace, comprises the hot-dirty gas vaporizing furnace body I and the hot-dirty gas reforming and purifying furnace body 2. The said hot-dirty gas vaporizing furnace body 1 is a high-temperature fluidized furnace. For liquifization, it adopts the mode of compact 15 multi-nozzle side spray at the top, and for gasification, it adopts the way of upward blow of the steam, oxygen or high-temperature air. At the upper part of the hot dirty gas vaporizing furnace body 1, the vaporizing chamber 3 is provided, with the fire-resistant furnacelinear and the thermal insulation external lining. At the lower part of the said hot-dirty gas vaporizing furnace body 1, the settling chamber 4 is. 20 provided with the water-screen linear. At the lower part of the gasification chamber 1, the path 5 is connected with the hot-dirty reforming and purifying furnace body 2, which takes the fire-resistant material as the furnace linear and take the heat insulation material as the external lining. The gas is discharged from the top of the hot-dirty gas reforming and purifying furnace body 2. At the upper part of the hot- 4 dirty gas vaporizing furnace body 1, a plurality of gas nozzles 9 are provided, connected and linked with a coal injecting pipe 8. Above the hot-dirty gas vaporizing furnace body 1 and below the gas nozzle 9, a plurality of air nozzles 10 are inclined upwards and connected with the gasification chamber 3. In the middle 5 of the hot-dirty gas vaporizing furnace body 1 and below the air nozzle 10, a plurality of gas adjusting nozzles 11 are inclined upwards and connected with the gasification chamber 3. After the dry coal is crushed by the coal grinding machine, it is transferred to the feeding lock hopper 6, then to the coal injecting pipe 8 through a spiral feeder 7, then the high-temperature steam is provided through the 10 coal injecting pipe 8. With the steam, the coal dust is injected to the gasification chamber 3 through the gas nozzle 9. The steam is preheated by the high efficiency steam preheater and the air is preheated by the high-efficiency fan heater. The high-temperature (or oxygen) and water vapor after preheating are injected to the gasification chamber 3 through the nozzle 10 below the coal 15 injecting pipe 8, then the coal dust is blown and mixed fully in the gasification chamber 3 by the high-temperature steam and air injected by the air nozzle 10. The gas adjusting nozzle II can provide the high-temperature air (or oxygen) to the fumace, to adjust the gasification reagent. The crude coal produced, through the path, enters the hot-dirty gas reforming and purifying furnace body 2. The ash 20 in the crude gas, through gravity settling, enters the settling chamber 4. At the lower part of the said settling chamber, a plurality of cool-down nozzles 12, which gives the low-temperature steam, are provided. In the settling chamber 4, the water screen 13 is provided. At the bottom of the settling chamber 4, the waste outlet 14 is provided. At the waste outlet, the discharging lock hopper 15 is 5 provided. The ash becomes solid through the water screen 13. After solidifying, the ash is discharged by the discharging lock hopper 15, and the crude gas enters the hot-dirty gas reforming and purifying furnace body 2 through the path 5.
