In the near future, there are too many gas explosions and a variety of gas on the safety of the personal safety problems, which is important to the security problem. According to the combustion characteristics of the gas in the furnace, the safety control requirements are the main content of pre dryer, automatic ignition, combustion state monitoring, biomass burning machine not fire protection, flameout protection, gas pressure limit protection, insufficient air pressure protection, power-off protection, prevention of gas leakage accident measures etc.. Now let's discuss the problem of the ignition of the combustion engine.
A high methanol combustion engine combustion spark ignition, it is easy to realize automatic control. The combustion state must be monitored dynamically. Once the flame detector senses the flameout signal, it must be returned to the combustion machine in a very short time, and the combustion machine will then enter the protection state and cut off the gas supply at the same time.
The flame detector should be able to detect the flame signal normally, neither sensitive nor slow. It is generally required that the response time from a flameout to a flame detector to send out a flameout signal is not more than 0.2 seconds. When the combustion engine is ignited, the gas is poured into the gas and the gas is ignited by fire. The ignition action requires that the ignition temperature field is formed before the gas is passed in, which is convenient for ignition and combustion.
If the point does not catch fire, the flame detector does not detect the flame signal, and the combustor enters the protective state. The methanol combustion machine indicates that it is generally required for 2-3 seconds to pass through the gas. The combustion engine determines the flame signal sensed by the flame detector, and enters the protection state without fire, and keeps burning when it burns.
After starting the combustor, if the alarm light is on, at least 20 seconds later, reset the reset button again.
