Visual flame detection system of gasifier and control method of system

Abstract

The invention belongs to the field of gasifier safety techniques and particularly relates to a visual flame detection system of a gasifier, which comprises detection probes arranged on a furnace body, wherein the detection probes are used for acquiring image or video information in the gasifier and outputting the image or video information to data acquisition control cabinets through cables; the data acquisition control cabinets are used for performing analog-digital conversion of the received image or video information and outputting information to a server through cables or optical cables; and the server is used for processing the received information to obtain and display flame temperature field distribution and video images. Meanwhile, the invention further discloses a control method of the system. The detection probes are arranged to directly acquire the image or video information in the gasifier and then output the image or video information to the server for display, so that the working condition of combustion in the gasifier can be seen conveniently and visually. Besides, the server is used for processing the images or video information to obtain the flame temperature field distribution image, so that the combustion intensity of flame in the gasifier can be known quantificationally.

Description

technical field [0001] The invention belongs to the technical field of gasification furnace safety, and in particular relates to a gasification furnace visual flame detection system and a control method thereof. Background technique [0002] The gasifier burner flame has a strong luminous rate and can emit an almost continuous luminous spectrum. Most of the radiation sources are high-temperature carbon particles and pulverized coal particles generated during the combustion process. Infrared band. At present, in order to monitor the ignition state of the gasifier and the combustion conditions in the furnace, special, high-temperature resistant flame detectors are usually used to monitor the working conditions in the furnace. The flame combustion intensity cannot be directly observed the actual working conditions of the flame combustion inside the gasifier. Moreover, during the drying process of the gasifier, false alarms often occur, resulting in frequent encounters with the...

At present, in order to monitor the ignition state of the gasifier and the combustion conditions in the furnace, special, high-temperature-resistant flame detectors are usually used to monitor the working conditions in the furnace. The flame combustion intensity cannot be directly observed the actual working conditions of the flame combustion inside the gasifier. Moreover, during the drying process of the gasifier, false alarms often occur, resulting in frequent encounters with the flameout of the gasifier during the drying process. occur, thus affecting safe production and directly threatening the high-load, long-period stable operation of the gasification part
