PURPOSE:To provide the titled furnace having high rate of reaction and compact size, giving high gasification efficiency and composed of a coal powder gasification chamber provided with a burner for mixing and blasting coal powder and an oxidizing agent supplied through respective nozzles and with a molten slag discharging port placed at the lower end of the chamber. CONSTITUTION:The objective jet-layer coal gasification furnace 1 has a coal powder gasification chamber 2 provided with burners 7a, 7b blasting coal powder 10 and an oxidizing agent 11 through a nozzle 17, an orifice 3 attached to the upper end of the gasification chamber and a molten slag discharging port 4 placed at the lower end of the gasification chamber. The burners 7a, 7b are furnished with a mixing chamber 18 to mix coal powder 10 and oxidizing agent 11 and having an ejection port 17 at the tip end of the burner to eject the coal, etc., into the furnace, a coal powder nozzle 20 to supply the mixing chamber 18 with coal powder 10 and an oxidizing agent nozzle 16 to supply an oxidizing agent 11 to the mixing chamber 10. Coal gas can be produced in high efficiency by gasifying coal using the above coal gasification furnace.
