Coke oven temperature adjustment method

Abstract

The invention discloses a coke oven temperature adjustment method. The coke oven temperature adjustment method includes the step of determining the set values of thermal parameters of coke ovens according to the ambient temperature and the moisture content of mixed coal. The coke oven temperature adjustment method can achieve the consistency in the temperature regulation of the coke ovens, avoid the temperature fluctuation of the coke ovens, ensure controlled straight-line temperature of the coke ovens, effectively control the temperature difference between coke oven groups, ensure the stability of the temperature of the whole coke ovens and achieve the accuracy of the temperature regulation of the coke ovens.

Description

technical field [0001] The invention belongs to the technical field of coke oven temperature adjustment, in particular, the invention relates to a method for adjusting the temperature of a 2-1 series 7.63-meter coke oven. Background technique [0002] The domestic 7.63m coke oven is a super-large coke oven technology of German Unde Company. The existing 7.63m coke oven has the following problems: [0003] 1. During the operation of the coke oven, the use of the existing adjustment methods leads to large errors in the furnace temperature control, mainly due to different shifts, cognition, skills and habits, which will cause great differences in the furnace temperature control of the coke oven, which is easy to cause The inconsistency of the coke oven temperature control process causes the furnace temperature to fluctuate, and even the difference between a group of coke ovens is very large, which directly leads to the decline of the coke quality; [0004] 2. Climate change, ...

AI Technical Summary

Problems solved by technology

[0003] 1. During the operation of the coke oven, the use of the existing adjustment method leads to a large error in the furnace temperature control, mainly due to different shifts, cognition, skills and habits, which will cause great differences in the coke oven temperature control, which is easy to cause The inconsistency of the coke oven temperature control process causes fluctuations in the oven temperature, and even a group of coke ovens has a large difference, which directly leads to a decline in coke quality;

[0004] 2. Changes in climate and environment, moisture fluctuations in raw materials, and differences in coal volatiles have a greater impact on the temperature stability control of super-large coke ovens;

[0005] 3. In the coke oven failure state, the furnace temperature changes sharply. If it is not handled properly, it will cause problems such as coke generation and furnace body damage;

[0006] 4. There is a big time difference between the production section and the maintenance section of the 2-1 series coke oven, which brings about the problem of poor temperature stability of the coke oven group
