What are the safety ignition problems of combustion engines

In the near future, there are too many gas explosions and various gas accidents that threaten personal safety problems. It is important for safety problems. According to the combustion characteristic of gas in the chamber of a stove or furnace, the main content of safety control requirements have preliminary blowing, automatic ignition and combustion condition monitoring, the protection of the biomass particles combustion machine doesn't work, flame-out protection, gas pressure high and low limit protection, insufficient air pressure protection, power protection, measures to prevent gas leakage accident, etc. Let's discuss the safety ignition of the combustion engine:

Methanol burner gas burner should adopt spark ignition, easy to realize automatic control. The combustion state must be dynamically monitored. Once the flame detector detects the flameout signal, it must be fed back to the burner in a very short time. The burner then enters the protection state and cuts off the gas supply at the same time.

The flame detector should be able to detect the flame signal normally, neither sensitive nor insensitive. It is generally required that the response time from flameout to flameout signal from flame detector should not exceed 0.2 seconds. When the burner is ignited, the gas is connected, and the gas catches fire. Ignition action requires that the ignition temperature field be formed before the gas is put in, so as to facilitate ignition and combustion.

If the ignition fails, the flame detector cannot detect the flame signal, and the burner enters the protection state. Methanol burner says: it is generally required to judge the flame signal sensed by flame detector for 2-3 seconds when the gas is connected. If there is no fire, it will enter the protection state and maintain combustion when there is fire.

If the alarm light is on after starting the combustion engine, it is necessary to wait for at least 20 seconds and press the reset button again to restart.
