Whether the plant interlock includes a new hydrogen machine or not
Thread Content
Our system’s interlock only shuts off the outlet isolation valve of the new hydrogen unit, but it does not shut down the unit itself. So in the event of an accident, is it true that the safety valve on the outlet of the new hydrogen unit is the only thing that can be activated? How is your device designed?
Yes, this type of chain is unsafe and can easily lead to excessive exhaust pressure
The same here: the export shut-off valve is closed, but the new hydrogen generator keeps running.
So how do you handle it? Or does the plant interlock cause the safety valve of the new hydrogen compressor outlet valve to trip?
Our device doesn’t have this interlock
Is it necessary to manually shut down the new hydrogen machine after an accident occurs?
Manual interlock, interlock console button, direct stop
Our large-scale plant doesn’t have new hydrogen generators; it only has interlocks for its main unit.
If that’s the case, there is indeed a problem. Our new hydrogen generators generally only have their own interlocks. Other large interlocks will not be interlocked with the new hydrogen machine. The inlet and outlet isolation valves also close in an interlocked manner only after the new hydrogen generator is shut down.
