Sizing of Steam Lines - forbesmarshall.com

The steam pipe sizing can be done on the basis of two methods namely; A. Velocity. B. Pressure Drop. A. Pipe Sizing based on Velocity. Steam pipe sizing calculations are based on the specific volume of steam while using the velocity method. For dry saturated steam lines, the velocities considered range between 25-35 m/s. or 80-120 ft. /sec.

Steam Generator vs. Steam Boiler | Powerhouse

In a firetube design, a steam boiler is a pressure vessel comprised of a large shell in which the hot gases of combustion pass through one or more boiler tubes connected to the front and rear boiler sheet. The most common firetube type is the scotch marine firetube boiler, which utilizes a large furnace tube and many smaller boiler tubes.
