Problems solved by technology

At this time, due to the reduction of the air volume and air supply volume of the air inlet, the intensity of the flame is very weak, and it is easy to be disturbed by external factors and fluctuate left and right. At this time, it is easy to deviate from the detection range of the flame probe, and the probe current also decreases. , the disadvantage of causing the burner to automatically shut down

Embodiment 1

[0016] A kind of burner flame detection device, its structure is as follows figure 1 As shown, the detection device is composed of a handle 1, a burner 2 and a flame probe 3, the handle 1 is arranged at the rear of the burner 2, the structure of the burner 2 is cylindrical, and there are three flame probes 3 in the form of Dendrites are evenly distributed on the top of the burner 2. The structure of a common burner flame detection device is as follows: figure 2 As shown, compared with the common burner flame detection device, the present invention has the biggest difference in the quantity and arrangement of the flame probe 3, the common burner flame detection device has only one flame probe 3, which is a Font setting, on the basis of which, the present invention separates a plurality of probes, so that the formation of the flame and the current of the probes can be detected in an all-round way, and the situation of the burner being closed by mistake is effectively avoided. ...

Abstract

The invention relates to a flame probing device of a combustor, which comprises a handle, a combustor and 2-4 flame probes, wherein the handle is arranged at the back part of the combustor, the combustor is in a cylinder shape, and the probes are uniformly arranged at the top part of the combustor. Compared with the prior art, the flame probing device disclosed by the invention has the advantages of complete flame detection range and stable probe current; the formation of the flame can be effectively detected under any size and fluctuation of the flame; and a combustion manager is determined whether to open a gas valve by the current detected by the probes, and when the current is relatively stable, the problem that the combustor is closed by mistake can be effectively solved.

Description

technical field [0001] The invention relates to a detection device, in particular to a burner flame detection device. Background technique [0002] At present, there are two types of flame detection for burners. One is to monitor the flame with a photoresistor, and the other is to monitor the flame with an ionization electrode (also called a flame probe). When it goes out, close the gas supply valve in time to prevent gas leakage. [0003] The application environment of photoresistor monitoring is very demanding, and it should be cleaned frequently. Therefore, most of the general environment uses a flame probe to monitor the flame. But the flame probe also has certain disadvantages. When the temperature of the combustion box reaches the set temperature, the burner will automatically adjust the flame, generally the minimum is 20%. To maintain the temperature in the combustion chamber and prevent overheating. At this time, due to the reduction of the air volume and air sup...
