Effective Boiler-Level Control | HPAC Engineering

Depending on load variations and the size of a boiler, one of three principal level-control strategies typically is employed: single element, two element, or three element. Single-element control In a single-element strategy, one device measuring instantaneous drum level provides a control signal to a feedwater regulator (Figure 2).

2004-2-25 · Two-element drum-level control can best be applied to a single drum boiler if the feedwater is at a constant pressure. Two-element control (see Figure 4) includes the same level element used for the single-element configuration but has an added steam-flow element that provides a density-corrected mass flow-rate signal to control the feedwater flow.
