Problems solved by technology

It is manifested in serious leakage of coke oven body, high heat consumption of gas, uneven furnace temperature, unstable coke quality, and large chimneys often emit black smoke after loading coal
[0004] At present, the maintenance of coke ovens in China adopts heat preservation before dismantling, which is lowered from 1000 ℃ to normal temperature for cold repair, and no heat preservation is used during the masonry process. After repairing, the temperature is raised to above 1000 ℃ by normal temperature oven; and only during the dismantling process The supporter is installed, but no supporter or support wall is installed during the masonry and heating process, so that the longitudinal expansion of the furnace body is not protected

Embodiment Construction

[0022] specific implementation

[0023] A new process for thermal maintenance of the entire wall of a coke oven carbonization chamber, comprising the following steps:

[0024] (1) Insulation of the adjacent furnace wall of the coke oven carbonization chamber: use insulation materials to first insulate the silica bricks and then remove them, starting from one entire wall of the coke oven carbonization chamber to remove, build, and heat up to the first time During the whole process of coal loading, the adjacent wall is insulated throughout the whole process; the temperature of the vertical flue of the combustion chamber on both sides is always kept above 800 °C;

[0025] (2) The adjacent furnace wall of the carbonization chamber of the coke oven is supported: four-layer supporters are installed within a distance of 5.7m from the top to the bottom of the carbonization chamber since the roof is removed and the repair is carried out, and the new wall is synchronized in the carboniz...

Abstract

A new thermo repairing process is used for whole wall of coke-oven charring house. It is carried out by: supporting the wall and retaining the temperature of the wall neighboring the coke-oven charring house, repairing the whole wall and replacing the oblique canal of charring house, making sure the new wall smooth, no expansion and depression when the temperature is increasing, making damages of neighboring wall at a low level. The mended wall is smooth and vertical. The width of charring house is uniformly. Taper and height are acceptable. The effect is good in experiment.

Description

technical field [0001] The invention relates to a coke oven maintenance process, in particular to a new technology for thermal maintenance of the entire wall of a coke oven carbonization chamber. Background technique [0002] The coking oven is a large-scale industrial kiln that is continuously produced at high temperature for a long time. Compared with other industrial furnaces, it has a complex structure, a large amount of bricks, a long furnace life, and a large construction investment. Since the main body is a silica brick structure, production cannot be stopped for major or medium repair under normal circumstances. [0003] The 1# and 2# coke ovens of JISCO Coking Plant were put into operation in 1970 and 1973 respectively. With the continuous increase of the coke oven age, the 1# and 2# coke ovens are aging year by year. Part of the iron parts protecting the furnace were seriously deformed, and the protective pressure on the furnace body appeared to be insufficient. T...
