PROCEDIMENTO PER L'ESTINZIONE SECCA DEL COKE E IMPIANTO PER LA SUA REALIZZAZIONE

A dry coke quenching process comprises the steps of preheating coke from a coke oven to a temperature of not lower than 1200 DEG C. by way of burning over its layer a combustible gas mixed with heated air, cooling the coke first to a temperature of not lower than 700 DEG C. with a mixture of hydroca...

Beschreibung
Zusammenfassung:	A dry coke quenching process comprises the steps of preheating coke from a coke oven to a temperature of not lower than 1200 DEG C. by way of burning over its layer a combustible gas mixed with heated air, cooling the coke first to a temperature of not lower than 700 DEG C. with a mixture of hydrocarbons and water vapor, and then with an inert gas to a temperature of from 200 DEG to 250 DEG C. In the course of operation, coke, heated to a temperature of not lower than 1200 DEG C., is passed to the middle part of a chamber wherein a flow of a gas-steam mixture heated to a temperature of up to 700 DEG C. is introduced in countercurrent relation to the flow of coke. Resulting from the process of conversion of hydrocarbons with water vapor is gas containing hydrogen and carbon monoxide. The blast-furnace coke with a temperature of not lower than 700 DEG C. is passed from a middle part of the chamber to a lower part thereof wherein it is cooled to a temperature of 200 DEG to 250 DEG C. with a flow of circulating inert gas.
