In recent years, there are too many gas explosions and all kinds of gas threats to the personal safety question. It is very important for the safety question. According to the burning characteristics of gas in the furnace, the requirements for the safety control must include pre blowing, automatic burning, burning state monitoring, the protection of Bio particle incinerator point not on fire, the protection of flameout, the protection of gas pressure rugged limit , facilities for atmosphere pressure less than protection, power-off protection, prevention of gas leakage and disorder, etc. Let's talk about the safe burning of the fuel oil incinerator:
The fuel oil incinerator and gas incinerator should be equipped with electric spark to realize automatic control. Once the flame detector senses the flameout signal, it needs to feed back to the incinerator in a very short time, and the fuel oil incinerator will enter the protection status immediately, and cut off the gas supply.
The flame detector shall be able to sense the flame signal normally, neither lively nor slow. The normal request time from flameout to flame detector uncovering flameout light shall not exceed 0.2S. When the incinerator is burning, the fuel gas is introduced, and the fuel gas is on fire. The burning action request is generated before the gas is introduced, which first causes the burning temperature field for the convenience of burning.
Assuming that the point is not on fire, the flame detector cannot sense the flame light, and the incinerator enters the protection state. Evaluation and interpretation of fuel oil incinerator: it is generally requested that the incinerator verify the flame light number sensed by the flame detector within 2-3 seconds after the gas is injected. If it is not on fire, it will enter the protection state, and if it is on fire, it will remain on fire.
After the fuel incinerator is started, it is assumed that the alarm light is on. At this time, at least after more than 20 seconds, press the reset button again to restart.
