Problems solved by technology

[0002] At present, there are two methods of coking at home and abroad. One is the traditional coking method, which uses coking coal or coking coal plus a small amount of blended coal to coke in the traditional conventional coke oven. This method has a long history and mature technology, but the disadvantage is that it can only use less than There are many coking coals, and a large number of other high-quality coals cannot be used for coking because of poor or no caking properties
The second is to adopt a newer process to produce molded coke, using non-coking coal to produce molded coke, which expands the variety of coking coal. The disadvantage is that there are many procedures and complicated processes. The carbonization furnace used is a new type of special furnace. Mold operation is unstable, thermal efficiency is low, and maintenance is difficult, resulting in low coke production rate, poor quality and high cost of mold coke

Abstract

The invention is a method of producing section coke by traditional coke ovens, providing a method of producing section coke tar by existing mature traditional coke furnaces and rich high-volatility cherry-coals. First crushes char or carbonized materials of high-volatility cherry-coals, mixes in adhesive to form coke blanks, mixing the coke blanks with the high-volatility cherry-coals and puts them in a coke furnace for carbonization at high temperature, and finally leaving the furnace and extinguishing the coke and screening. It opens a new way of producing section coke by high-volatility cherry-coals in existing traditional coke furnaces, and can obtain the finished section coke and raw material for preparing coke blanks in primary carbonizing course.

Description

technical field [0001] The invention relates to a method for manufacturing coke. In particular, the production of coke from high volatile non-coking coals in conventional conventional coke ovens. technical background [0002] At present, there are two methods of coking at home and abroad. One is the traditional coking method, which uses coking coal or coking coal plus a small amount of blended coal to coke in the traditional conventional coke oven. This method has a long history and mature technology, but the disadvantage is that it can only use less than A large amount of coking coal, and a large number of other high-quality coals cannot be used for coking because of poor caking or no caking. The second is to adopt a newer process to produce molded coke, using non-coking coal to produce molded coke, which expands the variety of coking coal. The disadvantage is that there are many procedures and complicated processes. The carbonization furnace used is a new type of special ...
