Fire time control method, fire time control guidance display device, operating method of coke oven, and fire time control device

摘要

The method for controlling the fire time according to the present invention is a fire time control method for controlling the fire time of each carbonizing chamber in a coke oven in which a combustion chamber and a carbonizing chamber are alternately connected to form a furnace group, Obtaining a relational expression using the burning time for each carbonization chamber as a target variable and information on the furnace temperature for each carbonization chamber as an explanatory variable, the relational expression, and the temperature change tendency of the furnace temperature in the most recent predetermined period Calculating a temperature operation amount for each of the carbonization chambers so that the predicted next burning time becomes the preset target burning time, and the step of predicting the next burning time based on And D. converting the temperature operation amount of each chamber into the temperature operation amount of each combustion chamber.
