Temperature adjusting method for treating coal cake collapse and coal charging dead corner

Abstract

The invention provides a temperature adjusting method for treating coal cake collapse in a tamping coke oven and a coal charging dead corner in a top-charging coke oven. The method comprises the steps of adjusting coal gas amount entering an oven body in an early stage of coking time, and reducing coal gas supply amount; and recovering the coal gas supply amount in the tail stage of the coking time. The temperature adjusting method is simple and practical in operation, is little in cost investment, can effectively avoid high temperature accidents, coke firing and burning of an oven door, ensures coke quality, prolongs service life of the coke oven, reduces coking cost and improves stability of coke oven production.

Description

technical field [0001] The invention relates to a temperature adjustment method for dealing with the collapse of coal cakes in tamping coke ovens and the lack of coal charging in top-loading coke ovens. High temperature accidents, coke overfire and furnace door burning caused by missing corners of coal charging. Background technique [0002] With the shortage of coking coal resources and even the reduction of all coal resources, more and more domestic coking enterprises have begun to adopt tamping coking. Judging from the tamping coke ovens that have been put into operation, coal cake collapse accidents will occur in these tamping coke ovens. If there is no effective treatment method after the collapse of rammed coke oven briquettes, the coke in the carbonization chamber will be overheated, it will be difficult to push the coke, and the furnace door will be burned. Furnace production stability and coke oven longevity. [0003] In top-charging coke ovens, when there is a se...

Problems solved by technology

[0004] In order to solve the disadvantages of coke pushing difficulties, coke quality decline, coke oven production stability decline, and coke oven service life shortening caused by the above-mentioned coal cake collapse and coal charging missing corners, various methods have been adopted in the prior art, such as Put regulating bricks in the vertical fire passage of the combustion chamber corresponding to the collapsed coalification chamber or design a small partition wall for the furnace head in the regenerator.

However, these methods have disadvantages such as high cost, difficult operation, harsh operating environment, and poor precise control.
