Method for single monotonic calibration of pressure in large coke oven chambers

Abstract

The application discloses a large coke oven carbonization chamber pressure single monotonic calibration method, and mainly describes a large coke oven carbonization chamber internal raw coal gas, in the whole coking process, according to the pressure size change trend, through the measurement adjustment method, the coking period is divided into a plurality of section numbers, then fixed carbonization chamber pressure single monotonic control values are set in each section, so that the raw coal gas in the carbonization chamber can be smoothly discharged out of the carbonization chamber, reaches the gas collecting pipe, then reaches the gas suction pipe, and finally reaches the coal gas purification system, and the whole raw coal gas pressure control stable operation specification operation process is realized; the development of the carbonization chamber pressure single monotonic calibration method aims to balance the carbonization chamber in the initial coal loading period, so that the raw coal gas does not escape from the furnace body to cause the smoke ignition pollution phenomenon, and when the raw coal gas amount is reduced and the pressure is lowered at the end of the coking, the carbonization chamber negative pressure air suction into the carbonization chamber is avoided, so that the local overheating burning of the furnace body is avoided, and the furnace body quality and service life are not harmed.
