Steam power stations with pressure-fired boilers (Journal

Steam power stations with pressure-fired boilers are suitable for medium-load and base-load installations. Their advantage over conventional steam power stations lies in the small amount of space required, the lower boiler losses and the more favorable price. Authors: Pfenninger, H; Yannakopoulos, G. Publication Date: Wed Sep 01 00:00:00 EDT 1976.
