ABSTRACT:
A column of hot coke from a shaft furnace moves downwardly into a vessel which it fills and forms a pile. A gap is left between the angle of repose of the coke surface and the upper portion of the vessel. Water is sprayed onto hot coke as it enters the vessel. The gap is vented to an exhaust duct. A baffle near the center of the vessel deflects the material to the sides and creates a void in the center of the vessel, which void is also vented to the exhaust duct. More water is sprayed on the coke adjacent the void. Steam pressure in the vessel is reduced by a fan which pulls steam through the exhaust ducts. The steam pressure is regulated by a pressure controller which modulates a damper in the exhaust duct. A temperature controller regulates the flow of quench water to the vessel. This regulates the temperature and moisture content of the material being cooled.
