Abstract

PURPOSE: To obtain highly calorific gas by gasifying coal, with reduction in tar formation, by transferring to a gasification zone, the sensible heat of high-temperature waste gas obtained by burning unreacted coal-containing combustible material in a burning zone different from the gasification zone.
CONSTITUTION: Particulate coal is fed through a pipe 6 to the middle portion of a gasification zone 1 maintained at a superatmospheric pressure. From a pipe 7, a gasifying agent which gasifies coal and fluidizes coal particles, such as steam or air, is introduced to the lower portion of the gasifier 1, and fixed carbon is burned immeadiately under a distributing plate 13. From the bottom of the gasifier 1, ash which contains unburned carbon which has been incompletely reacted in the gasifying zone A, is discharged and is introduced through a pipe 8 to a combustion furnace 2. The combustion furnace is operated so that the temperature in the furnace is higher than that in the gasification zone A. The high-temperature waste gas and ash particles pass their heat to the gasifying zone A through the wall of heat transfer pipe 3 provided within the gasifier 1 and then, is discharged through a pipe 10 from the system.
