Title:
ENTRAINED BED COAL GASIFICATION OVEN
Document Type and Number:
Japanese Patent JP3504772
Kind Code:
B2
Abstract:
PURPOSE: To provide an entrained bed type coal gasification oven whose combustibility is improved by controlling the swirl occurrence of the gas in the oven.
CONSTITUTION: The combustor 1 is equipped with the pulverized coal burners 3 and the char burners 4 both of which are opened aiming at the center or its upper part of the slag tap 6, while the reductor 2 is provided with the pulverized coal burners 5 inclining toward the circumferential direction avoiding the center. The combustor 1 and the reductor 2 are connected in one cylinder with no neck. Based on these constitutions, the ignitability and combustibility of the burners in the combustor 1 are kept good, the gas is also prevented from excessively forming the swirling components whereby the overall combustibility is largely improved.
