Independent flameout alarm monitoring system of multi-combustor for combustion applying computer program

Abstract

The invention discloses an independent flameout alarm monitoring system of a multi-combustor for combustion applying a computer program. The system provided by the invention mainly comprises a photographic device, an image inputting device, a signal converting device, an image delineating device, a signal extraction device, a comparing device and a combustor flameout alarming device, wherein the photographic device is used for collecting a combustor flame image in a furnace; the image entering device is used for inputting the collected image; the signal converting device is used for converting the collected analog signal image; the image ring positioning device is used for delineating a combustor nozzle on a display; the signal extraction device is used for extracting the information of chromaticity, illumination and RGB (red, green and blue) three-color value in the delineated range; the comparing device is used for comparing the extracted signal and a default value; and after the combustor in the furnace is close to the flameout state, the alarm monitoring system automatically sends alarm signals after comparison according to the extracted information and the default value. By adopting the system provided by the invention, when the combustion state of a furnace combustor of a boiler is monitored, not only is the manual work labor intensity reduced, but also the probability of boiler accident occurrence is reduced greatly.

Description

technical field [0001] The invention relates to a flame monitoring system for a combustion furnace, in particular to a monitoring system for independently extinguishing an alarm of multiple burners of a combustion furnace by using a computer program. Background technique [0002] Now known and common boiler industry TV monitoring device is to directly display the video image of the furnace flame captured by the camera on the display screen of the monitor, and manually monitor the combustion state of the flame in the furnace and the working condition of the burner. However, this monitoring method requires the operator to monitor the flame image in real time for 24 hours to determine the operating status of the burner. At the same time, due to the large number of burners, manual monitoring of multiple burner videos at the same time may easily lead to missed viewing and false reporting. , increasing the probability of boiler accidents. The existing domestic monitoring and alar...

However, this monitoring method requires the operator to monitor the flame image in real time for 24 hours to determine the operating status of the burner. At the same time, due to the large number of burners, manual monitoring of multiple burner videos at the same time may easily lead to missed viewing and false reporting. , which increases the probability of boiler accidents

The existing domestic monitoring and alarming of the flame in the combustion furnace can only give an alarm signal in the case of an overall fire extinguishment of the combustion furnace, control and cut off the fuel supply to protect the safety of the boiler, but...
