A Coal Blending Method for Stable Coke Quality

Abstract

The invention provides a coal blending method for stabilizing quality of coke. A coal rock analysis method and a traditional coal blending method are tightly combined, a small coke oven autonomous coal blending coking experiment is assisted, detailed comparison is carried out for all determined data, in order to obtain a reasonable coal blending pre-arranged planning, and a finally determined coalblending pre-arranged planning can be applied to large industrial production and applications. Compared with the prior art, the method has the beneficial effects that: 1. a coal blending scheme is formulated by using the method, coking coal resources are reasonably utilized, a coal blending structure is optimized, and coal blending cost can be effectively reduced; 2. generation of coke quality fluctuation case due to an inappropriate coal blending proportion is avoided, coal blending accuracy degree can be effectively supervised, and stable coke quality is ensured; 3. coal blending process and coal blending quality supervise are more scientific and standard, and operability is better.

Description

technical field [0001] The invention relates to the technical field of coking, in particular to a coal blending method for stabilizing coke quality. Background technique [0002] The traditional coal blending method simply relies on the industrial analysis of washed coal and blended coal and the G and Y value indicators to formulate a coal blending plan, and cannot supervise and control the quality of blended coal; although coal rock analysis methods can monitor and control the quality of blended coal, they cannot To detect and quantify the ash and sulfur content in coal, and closely combine the coal rock analysis method with the traditional coal blending method to carry out scientific coal blending and coke quality control research, highlighting their respective effects, abandoning their respective deficiencies, complementing each other's advantages, and fostering strengths and avoiding weaknesses , is being popularized and applied in the actual production of coking plants....

[0002] The traditional coal blending method simply relies on the industrial analysis of washed coal and blended coal and the G and Y value indicators to formulate a coal blending plan, and cannot supervise and control the quality of blended coal; although coal rock analysis methods can monitor and control the quality of blended coal, they cannot To detect and quantify the ash and sulfur content in coal, and closely combine the coal rock analysis method with the traditional coal blending method to carry out scientific coal blending and coke quality control research, highlighting their respective effects, abandoning their respective deficiencies, complementing each other's advantages, and fostering strengths and avoiding weaknesses , is being popularized and applied in the actual production of coking plants

Monitoring the quality of coal blending in daily production through coal rock analysis, there is no relevant report in China
