Problems solved by technology

The angle of view of the probe of this type of flame detector is fixed and small, and the probe is always aimed at the position of the initial combustion zone of the flame. Since the flame in the combustion zone changes dynamically, false alarms and missed alarms may occur from time to time. The commissioning personnel cannot see the actual flame changes, and the parameter setting is also very complicated, which seriously affects the safe operation of the boiler

Embodiment Construction

[0010] exist figure 1 , 2 middle , the system has an integrated block which is electrically connected with the probe 1, the processor 2, the display 3, the parameter setter 5 and the relay 6. The form of this integrated block can avoid the transmission caused by the separation of the probe and the processor. Distortion and loss can keep the signal waveform of the flame as complete as possible; the processor 2 of the system is electrically connected to the communication converters 4 and 12, and communicates with the upper computer PC8 through the communication converters 4 and 12 to form a local area network The probe detectors 7 and 13 have a 24V DC power supply; 2-core twisted-pair shielded cables 10 and 11 are laid in series between the host computer PC8 and the communication converters 4 and 12 and the probe detectors 7 and 13, and are detected by the probes The output signal of the detector is sent to all system units, thus forming an intelligent integrated flame detecti...

Abstract

The invention relates to an intelligent integrated flame detecting system which is provided with a probe, a processor, a monitor and an integrated block formed by a parameter setting device and a relay which are electrically connected into a whole; the processor of the system is electrically connected with a communication converter, and carries out communication link with an upper computer PC by the communication converter to form a local area network; the detector of the probe is provided with a 24V direct-current power supply; a 2-core twin twisted strand shielded cable is serially connected and laid between the upper computer PC and the detector, the detector outputs a signal to all system units, thus forming a combined system. The system can be applicable to the protective systems of various boilers, moreover, the actual flame change can be seen directly by inspectors by the monitor, parameters can be set conveniently by using a touch screen, the debugging is simple, and the occurrence of the situations of misinformation and omission can be precluded.

Description

technical field [0001] The invention relates to an intelligent integrated flame detection system for intelligent detection, processing, display and setting protection of boiler furnace flame. Background technique [0002] At present, in thermal power plants, the boiler furnace safety protection system (FSSS) uses conventional fire detection to protect the furnace fire. This conventional fire detection mainly relies on photoelectric components such as ultraviolet, infrared and visible light to detect flame intensity and frequency. Judge the condition of individual burner flames. The angle of view of the probe of this type of flame detector is fixed and small, and the probe is always aimed at the position of the initial combustion zone of the flame. Since the flame in the combustion zone changes dynamically, false alarms and missed alarms may occur from time to time. The commissioning personnel can't see the actual flame changes, and the parameter setting is also very complic...
