Abstract

Reheat boilers designed to operate with low furnace exit-gas temperatures and at the same time to provide control of superheater and reheater-outlet steam temperatures over a wide load range are illustrated and described. Various means for controlling primary and reheat-steam temperatures are discussed as are design provisions for some of the operating and maintenance problems peculiar to reheat units. Some advantages and disadvantages of indirect reheating are given.
