After the heating furnace goes out, what measures can be taken for safety reasons?

1. Purge with steam. 2. When igniting, avoid continuous ignition. When ignition fails, pay attention to purging, especially fuel gas. 3. Pay attention to personal self-protection during ignition observation to prevent backfire from injuring people.

Agree with the third floor's opinion. For atmospheric and vacuum furnaces, if roof-reducing gas is introduced into it, it must be cut out in time and introduced again after it is normal. When igniting, please pay attention to check that the fuel gas does not contain liquid.

Measures taken by our device after the heating furnace stalls during actual production: 1. Quickly close the hand valve of the extinguished flame nozzle. 2. Disconnect all the soft connections of the flame nozzle from the burner. 3. Open the heating furnace flue baffle, natural ventilation door and secondary air door. 4. Start the induced draft fan to replace the furnace. 5. Take a gas sample from the furnace and analyze the hydrocarbon content. 6. After the hydrocarbon content is qualified, light the steady light or flame nozzle. At this time, whichever burner is connected to the soft connection, and the rest should not be connected. This can effectively prevent the flash explosion of the heating furnace ignition due to internal leakage of the hand valve.

The method we use after the heating furnace of our hydrogenation unit is turned off: 1. Determine whether the cause of the heating furnace flameout is chain linkage or fuel gas. 2. If only the main burner is extinguished but the steady light is not extinguished, close the main burner fuel gas valve. 3. If the main burner and the continuous light go out together, close the main pipe valves of the continuous light and the main burner and the hand valve of the burner, open all fire viewing windows, and at the same time open the furnace purge steam for at least 15 minutes. 4. If it is an oil-burning stove, close the fuel oil and atomized steam hand valves. When dealing with a furnace fire-fighting accident, be sure to close the main fuel gas valve to prevent a large amount of fuel gas from flowing into the furnace and causing an explosion when re-ignited.

We install a heating furnace that burns fuel gas. When the heating furnace is turned off, the following methods are adopted:: 1. Protection after normal furnace extinguishing 1. Confirm that the burner and the continuous light of the heating furnace have been extinguished 2. If the temperature of the furnace is relatively high, turn on the fire extinguishing steam to cool the furnace 3. At the same time, blind the roots of each burner and the continuous light. 2. Extinguish the furnace in an accident 1. First, determine the cause of the heating furnace flameout, whether it is caused by chain linkage or fuel gas interruption. If it is a chain furnace failure, 1. First confirm whether the continuous light of the heating furnace is extinguished. If it is, 2. Open the furnace to purge the steam, fully open the flue baffle, and purge the combustible medium in the furnace to prevent explosion. 3. Eliminate the chain. If the fuel gas is interrupted, 1. Fully open the flue baffle, open the furnace to purge the steam. 2. Close the continuous light and the root valve prompt of the burner.: 1. Before starting the furnace, open the furnace to purge steam and purge the chimney of the heating furnace to see steam for at least 15 minutes. 2. When handling a furnace fire-fighting accident, be sure to close the main fuel gas valve to prevent a large amount of fuel gas from flowing into the furnace and causing an explosion when re-ignited. 3. Take a gas sample from the furnace before lighting the furnace to analyze the hydrocarbon content. 4. After the hydrocarbon content is qualified, light the continuous burner or burner. At this time, remove the blind plate of the burner or burner according to which burner is lit. Do not dismantle the rest. This can effectively prevent flash explosions in the ignition of the heating furnace due to leakage in the hand valve.

What is the purpose of lighting a lantern? Thanks

The purpose of lighting the lamp: First, you can control the heating rate of the furnace or furnace outlet in the early stages of lighting the furnace, and then use a constant light to light the main burner.
