Generic Boiler | Operation

The boiler subsystem is responsible for generating the steam pressure used in steam turbines. The actual boiler is used for both tandem and cross-compound machine. The boiler block diagram is shown in Figure 5 - 24. The upper part of this figure presents the boiler pressure regulator, and the lower part presents the boiler itself. The boiler input is the high-pressure steam flow mhuh and the output is the boiler pressure psih. As mentioned earlier, the boiler subsystem includes a PI type pressure regulator that controls the steam pressure output. Since the boiler has slow dynamics with respect to the other model, this subsystem is often neglected and set as a constant pressure source.
