FIELD: chemistry.
SUBSTANCE: invention can be used in chemical-recovery industry. Through a feed pipe 19, inert gas is fed into a cooling chamber 3 of a coke dry quenching plant 1, where it exchanges heat with red hot coke. The heated inert gas comes out through a ring opening 20 in the first dust collector 4. Air is fed into a pre-combustion chamber 2 through a nozzle 17. Temperature sensors 10 are fitted on the inner circumference of the coke dry quenching plant 1. The measured value of temperature inside the pre-combustion chamber 2 is sent to an airflow controller 12, which controls volume of air and circulating gas, fed into the furnace.
EFFECT: invention allows for preventing change of temperature inside the pre-combustion chamber and stabilising operation of the coke dry quenching plant.
