METHOD FOR ESTIMATING TEMPERATURE OF CARBONIZED PRODUCT IN CHAMBER TYPE COKE OVEN

摘要

PROBLEM TO BE SOLVED: To provide a method for accurately estimating the temperature of a carbonized product at the center part in the width direction of a chamber type coke oven, at the site corresponding to a flue with combustion failure.SOLUTION: The method for estimating the temperature of a carbonized product in a chamber type coke oven includes steps of: measuring the flue temperature and the oven wall temperature when cokes are extruded; obtaining the relation between the flue temperature of a flue with combustion failure and a plurality of carbonization chambers adjacent to the flue and the oven wall temperature on the carbonization chamber side at the flue position in advance; estimating the oven temperature on the carbonization chamber side at the flue position from the measured flue temperature of the flue with combustion failure in the actual coke oven based on the relation; obtaining the oven wall temperature on the combustion chamber side at the flue position from the estimated oven wall temperature on the carbonization chamber side; estimating the temperature at the central part in the width direction of the carbonization chamber at the region from the obtained oven wall temperature on the combustion chamber side based on the one-dimensional heat transfer calculation; and obtaining the relation based on the contribution ratio of the heat sneaking from the flue with combustion failure and the neighboring sound flues to the oven wall temperature at the position of the flue with combustion failure.
