  • Automatic Level Control Systems

    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.

  • Boiler Efficiency and Combustion

    Advantages of an on/off control system: Simple. Least expensive. Disadvantages of an on/off control system: If a large load comes on to the boiler just after the burner has switched off, the amount of steam available is reduced. In the worst cases this may lead to the boiler priming and locking out. Thermal cycling. High/low/off control system

  • Controlling TDS in the Boiler Water

    By installing an automatic TDS control system the average boiler water TDS can be maintained at a level almost equal to the maximum allowable TDS as shown in Figure 3.12.9; Evaluating savings by reducing blowdown rate. If a boiler is to supply a given amount of steam, …
