The boiler-turbine unit control schemes have gone through several decades of evolution and, typ-ically, a cascade of PI/PID controllers based on single-input single-output control loops is designed in the plant to fulfill such tasks.6,7 The remain-der of this section will focus mainly on the con-ventional boiler-turbine coordinated control systemLearn More
Water-tube boilers; in which the water circulates through tubes exposed to the furnace heat. The Babcock and Wilcox boiler (Fig. 7) is typical of this variety. (2) Fire-tube boilers; in which the hot gases pass through tubes surrounded by water. The ordinary locomotive boiler (Fig. 6) illustrates this form.Learn More
