The original poster didn’t provide enough details regarding the conditions under which the automatic start-up interlock for the burner cooling water pump should be activated; if it’s a normal startup, then a signal from the instrument DCS system is sufficient； If the gasification furnace is in operation, caution should be exercised when testing interlocks; in such cases, it can be done step by step: first, test whether the signal interlocks are functioning properly ； Pump reversal is then carried out on-site; however, it is generally not recommended to do so, as the gasifier has extensive interlocks – there are interlocks related to both the flow rate of the burner cooling water and its temperature, which can easily lead to shutdown incidents. Be careful, be very careful!
In the case of parking, it is signaled by the instrument panel
If parking, the pump can be stopped for debugging
Our equipment has not yet entered full production; it is currently in the testing phase. I would like to know how the automatic start-up interlock for the burner cooling water pump is being tested at present
When the unit is not in operation, it can be tested individually: engage the interlock, stop the operating pump, and then check whether the backup pump will start automatically.
Generally, it’s tested before driving, and there are few tests during operation
It is possible to test the interlocks during the time before starting up after maintenance, and it is quite necessary to do so.
