Automation control method for coke oven heating

Abstract

The invention relates to a coke oven heating automatic control method; in the method, the temperature of a coke oven is measured, a coke oven heating gas flow rate model and a sub-flue suction model are used for calculating heating gas flow rate Q and sub-flue suction a which are respectively controlled to realize the control over the temperature of the coke oven. The method can achieve the purposes of enhancing the control precision of the temperature of the coke oven, improving the quality of coke, maximally reducing the heat consumption in coking and saving energy by mastering and utilizing the change law of the temperature of the coke oven in the coke oven heating automatic control process.

Description

technical field [0001] The invention relates to the field of coke oven heating, and more particularly, the invention relates to an automatic control method for coke oven heating. Background technique [0002] In the total energy consumption of coking, the energy consumed by coke oven heating accounts for about 70% of the total energy consumption of coking, so coke oven heating control is a key link in coking production, and the quality of temperature control will directly affect Coking product quality, coke oven life, energy utilization and environmental protection and other issues. [0003] Fig. 1 shows a typical coke oven body, coke oven foundation and the sectional view of the main equipment. The uppermost part of the coke oven is the furnace top area 1, and below the furnace top area 1 are the combustion chamber and the carbonization chamber 2 (Fig. only shows the carbonization chamber 2, the combustion chamber and the carbonization chamber 2 are on the same level, not ...

AI Technical Summary

Problems solved by technology

[0012] The present invention is based on the fuzzy control technology of coke oven thermal theory, and aims at the defects of inaccurate control and poor stability in the prior art, and provides an automatic control method for coke oven heating with precise control and good stability

[0013] Coke oven heat transfer is a complex and unstable process. Most of the existing research and development of automatic control methods for coke oven heating are based on in-depth research on coke oven heat transfer.
