A method of correcting coke oven gas flow

Abstract

The present application relates to a kind of methods for correcting coke oven gas flow, it is characterized in that, step one: in the top of coke oven gas pipeline and horizontal position opening, ball valve is welded on opening;Step two: by top ball valve insertion image probe, image probe detects 360 ° in pipeline, according to the calculation coke oven gas pipeline actual cross-sectional area of image probe observation situation;Step three: according to the measurement result of coke oven gas pipeline actual cross-sectional area to coke oven gas flowmeter deviation correction.The present application can timely correct coke oven gas pipeline cross-sectional area by investigating the scale deposition in coke oven gas pipeline, according to the measurement result of coke oven gas pipeline actual cross-sectional area to coke oven gas flowmeter deviation correction.Make coke oven gas flow data relatively accurate, meet process, satisfy energy management demand.
