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.

All operating and limit controls and low water cutoffs must be tested for proper operation. 2.4.2 STEAM PRESSURE OPERATING CONTROL The steam pressure in the boiler is regulated by the Boiler Operator. This is a pressure control which senses the steam pressure and turns the boiler on and off accordingly. This control must be operationally tested.
back to saturated temperature of the boiler operating pressure. The most efficient system will be a condensate return system that is controlled at a pressure as close to the boiler operating pressure as possible. In a perfect system; the steam system for example, would operate at 150

On steam boilers operating at 15 psig or less, the steam heater typically operates at the same pressure as the boiler. On higher pressure steam boiler units, a pressure reducing station is typically installed in the supply line to the fuel oil heater to limit the steam pressure in the oil heater to 15 psig or less.

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.
Steam Pressure Limit Controls Application The P47 controls are designed for high limit, cutout, or operating control applications. When used as a limit or cutout control, the P47 is intended primarily to limit the pressures in steam heating systems. The controls which OPEN on a pressure increase are for use on high limit, cutout, or operating
High-pressure boilers are typically used for process loads and can have an operating pressure of 16 to more than 1,000 psig. Most steam boiler systems require saturated steam, which means the water and the steam in the vessel are at the same temperature. Steam and hot water boilers are defined according to design pressure and operating pressure.
