Dry quenching. Technical Principle:
Dry quenching is an energy-saving technology widely used in foreign countries, and its English name is Coke Dry Quenching, referred to as CDQ. CDQ technology uses cold inert gas (exhaust gas after combustion) to exchange heat with red hot red coke in a dry quenching furnace to cool red coke. The inert gas that absorbs the heat of red coke transfers the heat to the CDQ boiler to produce steam, and the cooled inert gas is then blown into the CDQ furnace by the circulating fan to cool the red coke. >>>More
