What is one function of a pressure control?

A pressure control is a critical component in a steam system as it helps regulate the pressure within the system to ensure safe and efficient operation. Specifically, by starting the burner, controlling the firing rate, or shutting down the burner based on the steam pressure, it maintains the desired pressure levels necessary for optimal performance of the boiler and associated equipment. This dynamic control is essential to prevent overpressure situations, which can lead to equipment damage or catastrophic failures.

In addition, maintaining the proper pressure also directly impacts the efficiency of the boiler and the overall steam system, ensuring that the steam produced is suitable for the intended applications. When the pressure reaches a predetermined set point, the pressure control will act to modulate the burner operation to either maintain that pressure or reduce it, illustrating the importance of this function in managing boiler operations effectively.
