Abstract

The invention discloses a furnace cleaning maintaining method in the coking furnace masonry course, which is characterized by the following: adopting lid to block slurry; blowing the flue for three times; sealing the inlet; cleaning incidence hole for two times; sealing incidence hole; blowing fire channel after building upper circulating hole.

Description

technical field [0001] The invention relates to a method for keeping the furnace body clean during the coke oven masonry process. Background technique [0002] The 7.63m coke oven is a high-tech coke oven type developed in Europe in recent years. This type of coke oven has the characteristics of high coke output, small footprint, and good environmental performance. Its coke output of 2*60 holes is equivalent to At present, the output of 6m coke ovens in China is 3*60 holes. The coke oven adopts a closed dust removal and coke discharge system, which greatly reduces dust pollution during coke discharge. Based on this, some domestic large-scale coking enterprises have introduced the technology of this type of coke oven and built them one after another. The furnace structure of the 7.63m coke oven is more complex than the current domestic coke oven type, especially the structural design of the brick gas channel, chute opening, chute expansion joint, vertical fire channel and ot...
