Methods to prevent burning out of fuel and gas burners
The fuel for fuel and gas burners is mainly composed of fuel and gas. Generally used in small and medium-sized oil or gas boilers. What are the methods to prevent it from burning out when using this burner? Here are some answers compiled by the editor of the European Security Council:
1. The reasons for the burning of fuel and gas burners are related to various factors, such as high furnace temperature of gas boilers, exceeding the allowable temperature, which enhances the radiation heat transfer of the burner by the high-temperature flue gas in the furnace, and increases the wall temperature of the burner nozzle, causing damage.
2. The burnout of fuel and gas burners may also be related to the deviation of the furnace flame foundation, because the furnace temperature and burner nozzle temperature distribution are uneven, and the nozzle wind speed of the four corner burners on the same layer of the boiler is also uneven, so the flame foundation is skewed.
When adjusting the gas boiler, if the secondary air speed is controlled too small, the ignition distance of the gas will be too close, causing the nozzle of the burner to deform due to overheating and eventually damage. In addition, when the high and low loads of the gas boiler change, if the adjustment is not timely and the upper secondary sealing nozzle is not frozen, it can also cause combustion of the fuel and gas burner.
The control system of the fuel and gas burner sends a command, and the gas supply system of the solenoid valve is quickly shut down. The gas power supply is cut off, and the burner is automatically purged after being shut down, indicating a fault. I hope the above content is helpful to you.
