Recently, there have been too many accidents involving gas explosions and the threat to human safety caused by various gases. Security issues are very important. According to the combustion characteristics of the gas in the furnace, the safety control requirements mainly include pre-blowing, active combustion, combustion state monitoring, maintenance of the biomass particle burner without ignition, flameout maintenance, maintenance of high and low pressure limits, maintenance of insufficient air pressure, and power failure Maintenance and measures to prevent gas leaks. Next, let's discuss the safe combustion of a fuel burner: a fuel burner gas burner should use electric spark combustion, which facilitates active control. It is necessary to monitor combustion conditions dynamically. Once the flame detector senses the flameout signal, it must respond to the burner within a short period of time. The fuel burner will immediately go into maintenance while shutting off the gas supply. The flame detector should be able to sense the flame signal normally, neither sensitively nor dullly.
It is generally required that the response time from extinguishing to the flame detector's extinguishing signal should not exceed 0.2 seconds. When the burner burns, gas is introduced and the gas is ignited and burned. Incineration requires the formation of a temperature field for incineration prior to the introduction of gases to facilitate ignition and incineration. If the ignition switch is not turned on, the flame detector cannot detect the flame signal and the burner enters a maintenance state. Fuel burners show that it usually takes 2-3 seconds to inject fuel gas. The burner judges the flame signal detected by the flame detector. If it is not on fire, it will go into maintenance mode, and if on fire, it will continue to burn. If the alarm light comes on after starting the fuel burner, after at least 20 seconds, press the reset button again to restart.
