Analysis of boiler interlock shutdown
Thread Content
The pressure in the fuel gas main pipe remained unchanged, and the control valve in the pressure regulation circuit was functioning properly; the system was under manual control before shutdown. Suddenly, the fuel gas pressure began to drop from the control valve down to its minimum value, which caused the furnace to stop burning and shut down. The control valve was found to be working fine when checked individually. Could anyone analyze the reasons from a process perspective?
Does it not show the reason for shutdown? What boiler
It is obvious that the boiler stopped burning due to the control valve being gradually closed or even the fuel supply being interrupted; therefore, to find the cause, it is necessary to determine what led to the control valve for fuel being closed. It belongs to the issue of automatic control for boiler fuel adjustment.
