OPERATION METHOD OF CHAMBER OVEN-TYPE COKE OVEN, AND CHAMBER OVEN-TYPE COKE OVEN

摘要

PROBLEM TO BE SOLVED: To provide an operation method of a chamber oven-type coke oven that can decrease the required amount of high-pressure ammonia water in a chamber oven-type coke oven where generated gases are sucked using a jumper pipe when charging coal, and a chamber oven-type coke oven.;SOLUTION: The operation method of the chamber oven-type coke oven comprises communicating a charging furnace 21 which is a carbonization chamber for charging coal with an adjacent furnace 22 which is a carbonization chamber adjacent to the charging chamber via a jumper pipe 13, sucking generated gases by ejecting high-pressure ammonia water from a vent portion 7 connected to both the charging furnace 21 and the adjacent furnace 22, when coal is charged into the charging furnace 21, setting the charging furnace high-pressure ammonia water ratio R, which is the ratio of (the flow rate of high-pressure ammonia water in the charging furnace)/(the total flow rates of high-pressure ammonia water in the charging furnace and the adjacent furnace), to a value smaller than 0.5 at the initial term of coal charge and changing the ratio so that the charging furnace high-pressure ammonia water ratio R is brought close to 0.5 with the lapse of time after the initiation of the coal charge. The chamber oven-type coke oven is also provided.;COPYRIGHT: (C)2010,JPO&INPIT
