Filed: 1992-07-24
Abstract: PURPOSE:To provide the subject method so designed that the exit of an oven for rapidly heating and pyrolyzing coal, etc., with a high-temperature gas is equipped with dust collectors and the high-temperature char collected is used as the heat source for coal gasification at an amount greater than the stoichiometric level, thereby controlling the temperature in the oven and improving its operability. CONSTITUTION:(A) An oven 7 for rapidly heating and pyrolyzing coal and carbonaceous feedstock(s) 1 fed from a hopper 2 using a high-temperature gas 9 is connected to (B) another oven 8 for producing such high-temperature gas 9 for promoting reaction through burning the coal and/or char, and the high- temperature char collected by dust collectors 11,12 at the exit of the oven 7 is recycled via feeders 14,16 to the oven 8 as the heat source fuel for coal gasification. For controlling the temperature in such an oven 7 for producing a gas, tar and solid char, the char collected is recycled at an amount greater than the stoichiometric level based on the amount of an oxidizing gas for combustion to extend the working life of the oven 7 and reduce the heat loss through the oven wall, thus improving oven operability.
