Pressure and Temperature Control Valves | Pilot

Pilot operated pressure regulating valves are commonly used for two applications within boiler feed systems: pressure control for pressurized deaerators, and temperature control for atmospheric feed tanks. When used on a deaerator, the main regulating valve is paired with a pressure pilot to create a pressure reducing valve.

Boiler Operation and Controls - Wiki - odesie by Tech

For most packaged boiler installations, the basic boiler control is a single -element, proportional control device. In the case of a steam boiler, the control device is a pressure sensing element that sends a signal to the burner management system to adjust the burner firing rate to maintain a set pressure in the steam distribution system.

Steam Pressure Reduction: Opportunities and Issues

2013-9-26 · Steam Pressure Reduction: Opportunities and Issues varies directly in proportion to the boiler's net stack temperature (the difference between the flue gas tem-perature and combustion air temperature). When boiler pressure is lowered, a lower stack temperature results. This, in turn, causes slightly improved combustion efficiency.
