An emergency power supply has been designed for the dry powder process; in the event of a power outage, this emergency supply can provide power to cool the gasification furnace and ensure water supply to the equipment. Is an emergency power supply also included in Texaco’s current design? What is the reason for not designing it?
Generally, the burner cooling water pump is equipped with an emergency power supply; the high-pressure ash water pump also had one originally, but it was removed later. These are all safety interlocks designed to maintain system stability, and of course, the DCS also has such mechanisms. . . . . . . . . .
Is your home’s burner water system equipped with an emergency power supply? In that case, is there still an accident cooling water tank? It should be possible to eliminate it!
We also have a pump designed for cooling the burners here; it was tested during the last maintenance session, but it doesn’t seem to enable a seamless switchover. If such a seamless switchover isn’t possible, I don’t think it’s very useful – at best it could be considered emergency power, but not true accident power. Additionally, there are mixers for the clarification tank and the large coal slurry tank as well; I believe that all the equipment that is crucial on-site should be equipped with accident power. As for the high-pressure ash pump mentioned earlier, since it operates under high voltage, it might not be suitable for having accident power designed for it. The accident power for the DCS is called UPS, which is an uninterruptible power supply that allows for a seamless switchover, similar to batteries. Accident power is likely to be a completely separate power supply from the normal power supply.:)
Texaco has designed an emergency power supply, a burner cooling water pump, and a slurry tank mixer.
Most are equipped with diesel generators that start within 15 seconds, but there are also issues – the startup time seems a bit slow.
