Description

technical field [0001] The invention belongs to the technical field of gasification furnace detection, and relates to a gasification furnace flame detection device and detection method. Background technique [0002] The gasifier is the key equipment of the coal chemical industry, which produces coal gas through the processes of thermal decomposition, gasification and combustion reaction of coal. Gasifiers require high-reliability on-line detection equipment to facilitate real-time diagnosis of furnace combustion conditions, ensure that the furnace is in a specific high-temperature, high-pressure environment, and ensure safe, efficient and stable operation of the gasifier. [0003] The emergence of flame image processing technology has opened up a new way of thinking for the combustion diagnosis of industrial furnaces. The furnace flame monitoring system based on the flame image comprehensively uses visual technology and computer technology to collect the image of the flame ...

AI Technical Summary

Problems solved by technology

Existing flame video detection requires manual detection of flame combustion in the furnace to determine whether the gasifier is ignited. This method requires a high level of experience for monitoring personnel, and cannot achieve continuous, rapid and accurate detection of combustion in the furnace. And output control signals in real time, which cannot meet the needs of DCS for program-controlled refinement

[0005] Due to the requirements of high temperature, high pressure, and airtightness of the gasifier, the existing flame detection device cannot be used in the flame detection process of the gasifier.
