Boilers - an overview | ScienceDirect Topics
Boilers should run at design loads to achieve proper heat transfer efficiency – operating far from their optimum design results in wasted energy. If soot, slag or scale is allowed to build up on the inside or outside of the boiler tube banks it will act as an insulator causing losses in heat transfer efficiency and the boiler will not operate at its design capacity.
