Control of power boilers - Consulting - Specifying Engineer

Boilers producing saturated steam need only control pressure because the temperature is a thermodynamic property of saturated steam. Figure 2 shows a photo of a burner retrofit for a 50,000-lb/hour, 150-psi saturated steam boiler with a new burner assembly with combustion safety controls.

STEAM TEMPERATURE CONTROL OF A BOILER USING -

To control the steam temperature of the boiler heat transfer rate in boiler is controlled by manipulating fuel flow rate. The main steam temperature change is mainly caused by the fuel flow changes and heat transfer rate between various elements of boiler. In steady conditions, the heat transfer rate can be considered stable.

Steam Piping and System Sensor Location - Heat-Timer

Normally, the pressure is low, but sufficient enough to push the steam to the upper floors. In these systems, the boiler must be located below all the piping and all the radiators. Some Heat-Timer controls use an outdoor reset cycling concept that measures the return pipe temperature to measure how far did the steam travel within the piping.
