How Should an Industrial Gas Burner Respond to a Sudden Power Outage?
The magnetic valve must close within a response time of less than 5.9 seconds to prevent gas leakage. Gas leakage refers to both gas leakage through a pipeline to the environment and gas leakage through the end of the magnetic valve chip to the furnace. Environmental leakage may cause toxicity and explosion in the work site, which must be highly valued.
Firstly, ensure that the pipeline is sealed, and regularly check for any leaks. If there is a leak in the pipeline, it must be cleaned before use. Secondly, to prevent poisoning and the formation of explosive gas concentrations, it is required to have good ventilation in the work site: be equipped with continuous ventilation holes and forced ventilation equipment; in addition, fireworks and explosion-proof electrical components should be prohibited from being played on at the work site. Leaking gas may cause an explosion in the furnace.
Gas burner is a thermal device that delivers fuel and air to the furnace according to the desired concentration, speed, turbulence, and mixing methods, and ignites and burns the fuel in the furnace. Fuel is mainly petroleum and natural gas. It is commonly used in small and medium-sized petroleum or gas boilers.
There are three methods for handling gas leakage in the furnace:
1. Increase the pre-blowing time and blowout air flow to blow away or dilute the gas in the furnace;
2. Use two magnetic valves to be serially connected in the gas pipeline to improve system safety;
3. Use pipeline leak detection devices to detect gas leaks before ignition and before starting the gas burner. If gas leakage reaches a certain level, the gas burner will be locked.
