Power Engineering 3B1 Chapter 1 Flashcards | Quizlet

There are several factors that influence the natural circulation in a watertube boiler. These are: a. The height of the steam drum above the bottom drum or header. b. The amount of heat applied to the tube. The hotter the tube becomes, the more steam bubbles are formed, creating more mass differential and thus more circulation. c.

Drum Type and Once Through Boiler Design

In the once through boiler, many times the load change response is dictated by the firing system and its controls rather than the boiler, per-say. Once through boilers of super-critical pressure boilers have higher efficiency. However in the sub-critical range there is no difference in efficiency when compared to the drum type design. Generally
