What are the methods for dealing with emergency situations in 75t coal powder boilers?
Thread Content
I would like to ask the experts: in the event of a sudden power outage within the plant and a freeze of the DCS display while a coal powder boiler is operating normally, how should the operators handle this situation? I hope an experienced expert can explain the detailed procedure. Thank you, master.
Isn’t a DCS usually equipped with an independent power supply? In the event of such a highly unusual situation, it is recommended to stop the machine immediately using the emergency shutdown system designed for electrical equipment, which can only be activated with a key on the DCS; at the same time, someone should be sent to the site to operate the relevant manual valves in accordance with the emergency shutdown procedures.
What was said upstairs is correct; DCS systems usually come equipped with an independent power supply, and there seems to be a UPS as well.
