PROCESS FOR DRY COOLING OF COKE WITH STEAM WITH SUBSEQUENT USE OF THE SYNTHESIS GAS PRODUCED

摘要

A method for the dry quenching of coke using steam with subsequent use of the synthesis gas generated, the method involving the cyclic coking of coal to coke with the coke being sent to a quenching device after being discharged from the coke oven and steam being introduced into the quenching device for dry quenching, thus creating synthesis gas made up of carbon monoxide (CO) and hydrogen (H2) via a water-gas reaction, and the synthesis gas produced being fed to a further application. This method allows the heat generated during coking to be used for the production of useful synthesis gas which, in turn, can be used for a further purpose or in the heating process, thus on the whole achieving an extremely even energy balance throughout the entire process.

1. Method for the dry quenching of coke in which
coal is heated in a coke oven via heating by means of a high calorific gas and coke is obtained via cyclic coking, said coke being pushed out into a coke quenching car on completion of the coking, and the incandescent coke is transported to a coke quenching device in a coke quenching car in which said incandescent coke is quenched to a temperature below the kindling temperature by means of a quenching gas, wherein gaseous steam (H2O) is used as the quenching gas under the exclusion of air, said steam reacting at least partially with the incandescent coke according to the water-gas reaction to form synthesis gas made up of hydrogen (H2) and carbon monoxide (CO), and due to the dry quenching being carried out in a coke quenching device the hydrogenous quenching gas obtained is collected, and the gas mixture thus obtained is used for a further purpose.
