The invention discloses a simulation regulation and control method for reducing the burn-out rate of a dry quenching furnace, which utilizes an improved simulation device for the burn-out rate of the dry quenching furnace and a dry quenching furnace circulating gas optimization method, so that a coking enterprise can conveniently carry out analysis on the burn-out rate of the dry quenching furnace under different working conditions with lower cost and shorter period. A regulation and control scheme of circulating gas components in the dry quenching furnace is efficiently and accurately determined, and the burn out rate of the dry quenching furnace is effectively reduced; the related simulation regulation and control method is simple, convenient to operate, low in cost, short in period and suitable for popularization and application.

The invention provides a method for measuring the burn out rate of a coke oven carbonization chamber and a method for optimizing the burn out rate of the coke oven carbonization chamber. The method mainly comprises the following steps: recording the burn out rates of coke in pool powder and coke pushing dust removal powder transferred from coke combustion in the coke oven carbonization chamber as X1 and X2; then carrying out ash balance analysis on the burning loss amount of coke in the coke oven carbonization chamber to obtain an ash balance formula from the in-furnace coking coal to the wet quenching rear tank powder and an ash balance formula from the in-furnace coking coal to the coke pushing dust removal powder; substituting corresponding production data into the ash content balance formula, and calculating X1 and X2; the sum of the two is the coke burn-out rate in the coke oven carbonization chamber. The method is convenient for coking enterprises to know the burning loss condition ...
