In small steam plants, a portion of the steam generated by the boiler is used to operate the deaerator if "waste steam" is not available. Failure to maintain and properly operate the deaerator can lead to early failure of the boiler, steam using equipment, and the steam and condensate piping.
Learn MoreBoiler design. Contemporary boilers are significantly smaller than their counterparts of only 30 years ago. This reduction in boiler size has been brought about by users, who demand that boilers be: More efficient in terms of fuel input to steam output. More responsive to changes in demand. Smaller, and so take up less floor space.
Learn MoreEach steam boiler and fired pressure vessel installed and operate in this country shall have a valid certificate of fitness (CF). Hence, the steam boiler and fired pressure vessel shall first obtain design approval from the Department of Occupational Safety and Health, Headquarters before fabrication, installation or operation.

With this type of boiler, tubes house water and/or steam. At the same time, the combustion products are circulated through the tubes. In most instances, the watertube
Learn MoreAt the corner design buckstay is hinged to permit expansion on the furnace wall of steam boiler. Bucstay is designed to resist longitudinal load such as internal and external pressure, normal load such as internal pressure, moment bending because of support bracket of pressure part, and temporary load such as explosion, wind and seismic forces.
Learn MoreAn air cock is located in the uppermost steam space of a boiler, as shown in Figure 9-2. This design allows for air to enter and escape during filling and draining of the boiler. Before firing a cold boiler with no steam pressure, open the air cock to allow air to Figure 9-1Boiler fittings. NAVEDTRA 14265A 9-7
Learn MoreDesign temperature: Maximum mean wall temperature of pressure parts (tube, pipe, header and drum) that is to say the sum of the outside and inside pressure parts surface temperatures divided by two. A steam boiler is designed for design metal temperature which influence allowable stress values.
Learn MoreSteam Boiler The Function of Steam Boiler . The main function of a steam boiler is to producing, storing and troubling the vapor. The liquid contained boiler is nothing but a shell and the heat energy produced while burning of fuel will be moved to water, and then it converts into steam at the required pressure as well as temperature.
Learn MoreThe MegaSteam oil-fired steam boiler was designed specifically for residential use and achieves 86% AFUE efficiency with a 3-pass cast iron heat exchanger - the only one of its kind in the world. Its unique design makes it highly corrosion resistant, a fact that U.S. Boiler Company backs up by giving the MegaSteam the best warranty in its class.
