In recent years, there are too many gas explosions and threats to personal safety caused by various kinds of gas, which is of great importance! According to the combustion characteristics of gas in the furnace, the safety control requirements mainly include pre blowing, active combustion, combustion monitoring, protection of non ignition of biomass particle combustion engine, protection of flameout and gas pressure bump limit protection , insufficient air pressure protection, power-off protection, measures to prevent gas leakage, etc. Let's discuss the following issues about the safe combustion of oil burners:
The electric spark combustion should be selected for the fuel oil burner and gas burner, so as to complete the active control. It is necessary to monitor the combustion situation dynamically. Once the flame detector senses the flameout signal, it is necessary to react to the combustor in a very short time, and then the fuel oil burner enters into the protection situation to cut off the fuel gas supply together.
The flame detector shall be able to sense the flame signal normally, neither sensitive nor slow. Generally, the response time from flameout to flameout signal declared by flame detector shall not exceed 0.2S. When the combustion engine is burning, the gas is introduced, and the gas is on fire. The combustion action requires that the combustion temperature field should be formed before the gas is introduced to facilitate the ignition and combustion.
Assuming that the point is not on fire, the flame detector cannot sense the flame signal, and the combustion engine enters the protection condition. The fuel oil burner shows that it is generally required that the combustor judges the flame signal sensed by the flame detector when the fuel gas is injected for 2-3 seconds. If it is not ignited, it will enter into the protection condition, and if it is ignited, it will keep burning.
After starting the fuel burner, it is assumed that the alarm light is on. At this time, it is necessary to wait for at least 20 seconds, and then press the reset button again to restart.
