What is the purpose of the operating pressure control in a boiler?

The purpose of the operating pressure control in a boiler is primarily to ensure safety and prevent overpressure. This control mechanism continuously monitors the pressure within the boiler and automatically adjusts the system's operation to maintain pressure within designated safety limits. By doing this, it helps prevent dangerous situations that could lead to boiler explosions or failure, which could be caused by excessive steam pressure beyond the design capability of the vessel.

The importance of maintaining the proper pressure cannot be overstated, as it directly affects the overall safety of the boiler system and the efficiency of steam production. Without effective pressure control, the risks associated with boiler operation could lead to hazardous conditions for the plant personnel and equipment.
