Abstract

The invention relates to the production of coke, mainly to methods for dry quenching of coke, and allows for an increase in the yield of coke through the use of non-caking coal. When coke is loaded into the prechamber, non-caking coal with a particle size of less than 10 mm in the amount of 10-15% of the coke being charged is loaded with it, and the mixture of coke and coal is held in the prechamber for at least 45 minutes, after which it is cooled in the quenching chamber with circulating gases. 1 tab. oo ate with bJ so 1

Description

The invention relates to the production of coke, mainly to methods for dry quenching of coke.

The purpose of the invention is to increase the yield of coke through the use of non-flowing coal.

Example. In semi-industrial conditions, they mix and hold in a closed heat-insulated container for 45 minutes 100 kg of hot-rolled gross coke loaded at 1000 ° С and 10 kg of non-heated coal.

Mark 2CC with a particle size less than 10 mm, which is contaminated at 20 ° C. After the mixture is cooled, coke breeze with a thickness of less than 10 m 1 h is screened out on the screen, the yield of which is about 14.5% of the total mass of the mixture. The yield of coke breeze from the original coke after it cools is about 6.5%.

A technical analysis of non-caking coal and coke breeze is given in the table.
