Drum pressure the key to managing boiler stored energy

Most boilers on a given header must be allowed to be driven by the Plant Master to maintain pressure control. Boilers that have the Boiler Master set in automatic mode (passing the steam demand from the Plant Master to the boiler firing control system) are said …

Cascade, Feed Forward and Boiler Level Control – Control Guru

Sep 21, 2018 · 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.

In this type of system the feedpump runs continuously, and an automatic valve (between the feedpump and the boiler) controls the feedwater flowrate to match the steam demand. When operating correctly, modulating control can dramatically smooth the steam flowrate chart and ensure greater water level stability inside the boiler.

An automatic blowdown control system continuously monitors the boiler water, adjusts the rate of blowdown, and maintains the specific conductance of the boiler water at the desired level. The basic components of an automatic blowdown control system include a measurement assembly, a control center, and a modulating blowdown control valve.
