Embodiment Construction

[0081] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0082] Taking the temperature adjustment of the coke side of the new 1# coke oven of a steel company as an example to describe the specific implementation mode, the temperature of the fire path of the steel company is measured every four hours.

[0083] Such as figure 1 As shown, it is a flowchart of a method for automatically adjusting the flue temperature in the coke oven heating and combustion process based on performance evaluation according to the present invention. By collecting the historical data of the flue temperature operation, a multi-attribute performance evaluation model based on information entropy is established. Collect the data of the current flue temperature operation, use the multi-attribute performance evaluation model based on information entropy to judge the performance level of the current control system, establish a multi-object...

Abstract

The invention discloses a method for automatically regulating the temperature of a flame path of a coke oven in heating and combusting procedures on the basis of performance evaluation. The method includes acquiring historical temperature and running data of the flame path and building a multi-attribute performance evaluation model on the basis of information entropy; acquiring current temperature and running data of the flame path; judging a current performance level of a control system by the aid of the multi-attribute performance evaluation model on the basis of the information entropy; building a multi-objective optimization model according to the current performance of the control system; solving the multi-objective optimization model by the aid of a genetic algorithm; regulating parameters of a controller in the control system; automatically regulating the temperature of the flame path. The method has the advantages that the parameters of the controller in a production field can be automatically regulated by the method, so that the purpose of automatically regulating the temperature of the flame path can be achieved, the automation degree of coking production can be effectively upgraded, and an economic benefit of coking production can be effectively increased; running conditions of the control system can be accurately evaluated in coking production procedures by the aid of the online performance evaluation model on the basis of the information entropy, and accordingly a basis can be provided for optimizing the parameters of the controller.

Description

technical field [0001] The invention belongs to the field of coke oven heating and combustion process control, and relates to a method for automatically adjusting the temperature of a coke oven heating and combustion process based on performance evaluation. Background technique [0002] As a raw material for steel smelting, coke is widely used in blast furnace ironmaking, nonferrous metal smelting, calcium carbide, casting, gasification and other industrial fields, and is an important material basis for national economic development. In the iron and steel industry, the quality of coke directly affects the product cost and production quality of the enterprise, and restricts the growth of the economic benefit of the enterprise. Designing an optimal control system for the heating and combustion process of coke ovens and stabilizing the flue temperature of coke ovens play a very important role in reducing the production costs of coking enterprises and improving economic benefits...
