Abstract
PURPOSE: To enable the suspension of coke oven operation with minimum heat consumption, without damaging the oven, by maintaining the lowest temperature of the upper part of the combustion chamber and that of the regenerator to specific values, and controlling the combustion to minimize the temperature fluctuation.
CONSTITUTION: The temperatures of the combustion chamber and the upper part of the regenerator are maintained to ≥800°C and ≥700°C, respectively. The combustion chambers in a row are partially operated with short flame, and the temperature distribution in the chamber is uniformized. Heat insulation means are applied to the charging hole lids of the carbonization chamber, the basement of the ascention pipe and the end doors of the oven. The pressure in the carbonization chamber is kept positive by introducint an inert gas into the chamber to prevent the burning of carbon and the damage of refractory brick caused by joint-failure of brick, and to minimize the heat dissipation. The flow of the air for combustion and that of the exhaust gas are separately controlled to attain uniform heat flow throughout the regenerators.
