Since the final water drum may also be used to catch the "mud" (i.e. a "mud collector"), it is sometimes known as a "mud drum". Advantages. There are three advantages to the Stirling design: Owing to the multiple passes through the tube banks and the careful arrangement of circulation and feedwater, the boiler is generally quite efficient.Learn More
Jun 13, 2013 · The water then rises to the steam drum where saturated steam is drawn from the top of the drum. The watertube boiler has some relative advantages over the firetube boiler design, which are outlined below. Watertube boilers are safer by design and generally considered to last much longer than the firetube boiler.Learn More
(UP®) boiler with vertical, multi-pass furnace was developed by B&W to meet the base load and load cycling needs of U.S. utilities for supercritical boiler applications from the 1950s to the 1980s.
