2. Steam Pressure Control with Load Index

2.0. General

For any steam generation plant, steam pressure is the most vital parameter that indicates the state of balance between the supply of steam and the demand for it—that is, the supply of heat input or fuel and output as steam withdrawal from the system for various utilities like heating or power-generating turbines. If supply exceeds demand, the pressure obviously increases, whereas if demand exceeds supply, the pressure decreases. The control loop strategies discussed in this chapter are for a subcritical thermal power station (i.e., with a drum-type boiler).
