Problems solved by technology

However, domestic coking by-product yield prediction and research results on control methods are less
[0003] The former Soviet Union carried out relevant research on the prediction of coking by-products, and believed that the yield of coking by-products was related to the temperature of the coke center, but the research ignored the relationship between the yield of coking by-products and coking time, and the prediction was inaccurate; other domestic scholars on coking by-products Forecasts, most of them stay at the level of production experience formulas, and can only roughly estimate the yield of coking by-products

Embodiment Construction

[0041] The technical solutions of the various embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0042] combine figure 1 , with a group of specific examples of a 7.63m coke oven, the coking by-product yield control method of the present invention is described in detail:

[0043] (1) Determine the volatile content of blended coal: According to the coke grade requirements of the 7.63m coke oven, the coke grade for production is determined to be the first grade (M40>88%, M1068%, Ad<12.5% , S<0.7%), blended coal volatile matter Vdaf=25.0%;

[0044] (1) Establish a prediction mode...

Abstract

The invention relates to a method for controlling the yield of a coking by-product. According to the method, under the conditions of different mixed coal volatile matters, different coking times and different coking temperatures, heat value distribution of coal, coke, benzene, sulphur and coke oven gas are analyzed, an energy distribution coefficient caused by coke oven operations is calculated, further the distribution law of the yield of the coking by-product when the coking by-product is affected by coal mixing conditions and coke oven operation conditions is researched, and the complete method for controlling the yield of the coking by-product is established. Therefore, by means of the method, workers are guided to improve the yield of the coking by-product by controlling the ingredients of mixed coal and changing the coke oven operation conditions.

Description

technical field [0001] The invention belongs to the technical field of coal chemical industry, and in particular relates to a method for controlling the yield of coking by-products. Background technique [0002] At present, the income of coking by-products occupies an increasingly important position in coking enterprises. How to improve the yield of coking by-products under the premise of ensuring the quality of coke has always been an important research topic for coking workers. However, domestic coking by-product yield prediction and research results on control methods are few. [0003] The former Soviet Union carried out relevant research on the prediction of coking by-products, and believed that the yield of coking by-products was related to the temperature of the coke center, but the research ignored the relationship between the yield of coking by-products and coking time, and the prediction was inaccurate; other domestic scholars on coking by-products Forecasts mostly...
