Method of solving blowby of brick gas duct of coking furnace

The invention relates to a method of solving blowby of a brick gas duct of a coking furnace. The method comprises the following steps of: (1) preparing a grouting material: selecting a grouting agent,and mixing 10-15% of cement into the grouting agent to prepare the grouting material, (2) grouting: performing grouting on flues of burning chambers at grouting pressure of 0.16-0.32MPa for 10-15s, and adjusting the pressure at the same time, and (3) dredging: dredging the gas duct with a drill rod to ensure that the gas duct is not blocked by slurry. With the adoption of the method of solving the blowby of the brick gas duct of the coking furnace, the working efficiency is improved; at the same time, the temperature uniformity of the coking furnace is improved; the service life of the cokingfurnace is prolonged; poor coke maturity due to the blowby of the coking furnace is reduced; the coke quality is stabilized; and the loss due to the coke quality problems is reduced. 本发明涉及种解决焦炉砖煤气道窜漏的方法，包括以下步骤：（1）制作压浆料：选取压浆剂，
