Hydrogen chimney on fire

This post was last edited by sunjl1981 on 2013-1-6 at 20:27. If the hydrogen chimney catches fire while everything is operating normally, what’s the best way to deal with it? Should we adjust the reflux of the hydrogen compressor, reduce the amount of reflux, and pay attention to the pressure difference so that less hydrogen is released from PCV202? If the fire still doesn’t go out, can we use steam to extinguish it? I’m not sure if this is a good approach. I still have a question: when adjusting the reflux of the hydrogen compressor, will it be necessary to adjust the reflux of the chlorine compressor as well in order to maintain the pressure difference? # + +

Maintain positive pressure; use steam along with nitrogen for fire suppression. I’ve seen cases where only steam was used, and it took over four hours to put out the fire

A positive pressure must be maintained to prevent tempering

Reply to 1# Man’s True Nature: I would like to ask everyone, with a positive pressure and a pressure difference in place, is what I’m doing correct or not?

The possibility of the chimney catching fire is low. I’m not sure what the height of your water seal is; in the event of a fire, steam should be used to extinguish it first. If the fire gets out of control, reducing the current level could be considered. Adjusting the return flow merely involves making minor adjustments. Of course, it’s important to maintain the pressure difference in the main pipes to prevent backflow that could cause the system to shut down

What should be done if the vent pipe catches fire, and pouring in a large amount of nitrogen or steam fails to extinguish it, while reducing the volume of gas released also does not succeed in putting out the fire (with nitrogen flow continuing)? Should the vent valve be closed immediately while introducing a large amount of nitrogen? In the above situations, I would like to ask the experts how to handle them?

First, consider using steam or nitrogen to extinguish the fire; only if that doesn’t work should measures such as reducing the current be considered to adjust the pressure

Can it be achieved by adjusting the pressure difference? I’ll wait for experts to provide further answers!

Nitrogen + hydrogen, maintain pressure to prevent tempering!

If the hydrogen chimney catches fire during normal operation, it is necessary to maintain positive pressure, reduce the flow rate of the vent valve, introduce large amounts of nitrogen or steam, and use fire-fighting water to cool the vent pipe (you cannot extinguish the fire if the vent pipe becomes red hot).

Will the hydrogen water seal catch fire during normal operation? Do you release all of your hydrogen under normal conditions? Generally, nitrogen and steam are used for fire suppression during venting, right?
