[0002] Dry quenching furnace, namely coke dry quenching furnace, is the main equipment in coke dry quenching process. Its working principle can be referred to as follows: red coke is loaded from the top of the dry quenching furnace and reversely exchanges heat with low-temperature inert gas (such as nitrogen) which is blown by a circulating fan. In this process, the hot coke is cooled and the temperature is reduced to below 200℃, while the temperature of the inert gas is increased due to the absorption of the heat of the red coke. The heated inert gas flows through a dry quenching waste heat boiler for heat exchange to generate steam. Then, the inert gas is cooled and reblown into the dry quenching furnace for closed system circulation.
