Problems solved by technology

There is a coke oven ignition step in the desulfurization recovery process. The prior art is usually one-time ignition, that is, the main burner is directly ignited, which will cause uneven heating of the furnace body, making it easy for the gas in the furnace body to react. Abnormal situations such as explosions occur, and in addition, the service life of the coke oven will be reduced

Abstract

The invention relates to the technical field of coal chemical industry, and particularly relates to a coke oven ignition control method and a coke oven ignition control device; the method includes steps of i, orderly executing from 1 to N; step 101, judging if the control parameter corresponding to the i grade ignition process can meet the i ignition condition; if the control parameter corresponding to the i grade ignition process meets the i ignition condition, executing the step 102; or, executing step 103; step 102: igniting the i grade nozzle to execute the i grade ignition process; meanwhile, judging if the i grade nozzle is successfully ignited; if the i grade nozzle ignition is successful, adding 1 to i, and then returning to step 101; or, executing step 103; step 103: resetting i to 1, and then returning to step 101; when i is equal to N in step 102, completing the ignition i if the ignition of the N grade nozzle is successful, and not adding 1. The coke oven ignition control method and the device can guarantee the uniform temperature rise of the furnace body, and make the gas in the oven react safely, and improve the service life and the production safety of the cock furnace.

Description

technical field [0001] The invention relates to the technical field of coal chemical industry, in particular to a coke oven ignition control method and device. Background technique [0002] In the coke oven gas desulfurization recovery process, ensuring the normal and stable operation of the coke oven is a crucial prerequisite for coke oven gas recovery. There is a coke oven ignition step in the desulfurization recovery process. The prior art is usually one-time ignition, that is, the main burner is directly ignited, which will cause uneven heating of the furnace body, making it easy for the gas in the furnace body to react. Abnormal situations such as explosions occur, and in addition, the service life of the coke oven will be reduced. Contents of the invention [0003] In view of the above problems, the present invention is proposed to provide a coke oven ignition control method and device that overcomes the above problems or at least partially solves the above problems...
