Method for controlling temperature of super-huge coke oven

Abstract

The invention relates to a method for controlling temperature of a super-large coke oven. The method comprises the following steps of: 1) recoding coal loading time of each oven hole of the super-huge coke oven; 2) calculating and recording the time difference between the coal loading time of each oven hole in the step 1) and calculating time; 3) accumulating contributions, which correspond to all time differences in the step 2), of coal loading of the oven holes to obtain the coking process of the whole coke oven; 4) smoothly generating temperature indexes by using a plurality of contributions in the step 3), and calculating and simulating a coke oven temperature fluctuation movement track; 5) dividing the heating process of the coke coven into a plurality of sections according to the coke oven temperature fluctuation movement track which is established in the step 4), and dividing a temperature determining result of each section into a plurality of conditions; and 6) establishing the corresponding controlling adjustment scheme for each condition in the step 5).

Description

technical field

[0001] The invention relates to the design and application of a production process index and a temperature index of an extra-large coke oven, in particular to an oven temperature control method of an extra-large coke oven. Background technique

[0002] Although the impact of the coke oven charging time on the coke oven temperature has been recognized for a long time, the current research on the coke oven temperature and the sequence of coal charging in the carbonization chamber has not been digitally calculated. Only stay on artificial intuition, resulting in no precise control of furnace temperature, gas export, etc.

[0003] The 7.63-meter coke oven in China has not successfully adopted coke oven automatic control heating technology for a long time, while other furnace types mainly adopt cascade control schemes, and do not consider the coke oven temperature index, that is, the interlocking with coke discharge and coal charging temperature control scheme. ...
