Abstract:

 Analysis is carried out for problem of the higher temperature generated in the production space inside the top of 7.63m coke oven designed by UHDE in Germany and the method for the effective temperature reduction in the top inside the coke oven is narrated. The temperature in the top inside the coke oven is reduced from 950℃ to about 870℃ through adjustments of gas orifice plate and spray nozzle plate for regenerator, the gas consumption is reduced by over 15% in comparison with the earlier period of the commissioning and problem of graphite grown on the top inside the coke oven is solved.
