According to the combustion characteristics of the gas in the furnace, its safety control requirements mainly include pre-blowing, automatic combustion, combustion monitoring, protection of biomass pellet burners not igniting, protection of flameout, protection of gas pressure unevenness, air pressure Insufficient protection, power-off protection, methods to prevent gas leakage incidents, etc. Let's discuss the issue of safe combustion of oil burners together.
Oil burner gas burner should use electric spark combustion to facilitate automatic control. The combustion situation must be dynamically monitored. Once the flame detector detects the flameout signal, it must be reflected to the burner in a very short time. The oil burner will enter the protection situation and cut off the gas supply at the same time.
The flame detector must be able to sense the flame signal normally, neither active nor inactive. It is generally required that the response time from flame out to the flame detector's announcement of flame out signal should not exceed 0.2 seconds. When the burner is burning, gas is introduced, and the gas ignites and burns. The combustion action requires that the combustion temperature field be formed before the gas is introduced to facilitate ignition and combustion.
Assuming that the point does not ignite, the flame detector cannot sense the flame signal, and the burner enters the protection situation. The oil burner shows that: Generally, it is required that the burner judges the flame signal sensed by the flame detector within 2-3 seconds after the gas is introduced. If it is not on fire, it will enter the protection situation, and if it is on fire, it will maintain combustion.
After starting the oil burner, suppose the alarm light is on. At this time, at least 20 seconds after the demand ratio, press the reset button again to restart.
