Method for increasing blending amount of gas-fat coal

Abstract

The invention discloses a method for increasing the blending amount of gas-fat coal. The method comprises the following steps of: 1) grinding and collecting coke powder with the granularity being 0.2mm; 2) breaking the gas-fat coal and leading the granularity of the gas-fat coal to be 3mm; 3) uniformly mixing the coke powder and the gas-fat coal according to a weight ratio of 1:30; 4) carrying outgranulation on the uniformly-mixed coal material by high-pressure paired rolls to lead the granularity of the granulated coal material to be 5mm; 5) blending the granulated coal material by increasing 3.5% on the basis of the original use ratio of the gas-fat coal, and then carrying out coking. The method disclosed by the invention has the beneficial effects that on the basis of the original useof the gas-fat coal, the use amount of the gas-fat coal is further increased, so that the coking coal resources in Xinjiang can be fully utilized and the production cost of an enterprise can be reduced.

Description

Technical field [0001] The invention relates to a method for increasing the mixing amount of gas, fertilizer and coal. Background technique [0002] 1890 coal is the unique high-quality gas fat coal of Bayi Iron & Steel Co., Ltd., but the increase of its blending amount has always been a fatal factor that prevents the increase in coke thermal state. Through the experiment of 1890 limit blending, it has been mastered that the 1890 blending amount can reach up to 40%, but due to the actual coking coal resource limitation, it cannot be used in actual production. At present, the actual production capacity of 1890 is not equal to the actual coal blending demand, and the advantages of its own mineral resources cannot be fully utilized. The world's coking coal resource reserves do not match the actual demand. On the one hand, it depends on and demand for main coking coal. On the other hand, the natural reserves of main coking coal are much lower than the actual reserves of gas and fat ...

[0002] 1890 coal is a high-quality gas-fired coal unique to Bayi Iron and Steel Co., but the impact of increasing its dosage on the thermal state of coke has always been a fatal factor that has plagued the inability to increase the dosage

Through the experiment of 1890 limit allocation, it is now known that the 1890 allocation can reach up to 40%, but due to the limitation of actual coking coal resources, it cannot be used in actual production and application

At present, the actual production capacity of 1890 is not equal to the actual coal blending demand, and the advantages of self-owned mineral resources cannot be fully utilized
