A surface condenser is a water-cooled shell and tube heat exchanger installed to condense exhaust steam from a steam turbine in thermal power stations.
A recuperator is a heat exchanger that transfers heat from a hot fluid to a colder fluid without mixing the two. Recuperators are used in many applications, including: Recuperator are often designed with counterflow arrangements, where the fluids move in opposite directions to increase heat exchange efficiency. This mechanism is...
Tubular exchangers are in general designed in accordance with various standardsand codes, such as the standards of the Tubular Exchanger Manufacturers Association(TEMA) and the American Society of Mechanical Engineers, ASME – API Unfired PressureVessel Code. Standards devised and accepted by TEMA are available covering in detail thematerials,...
A tubular heat exchanger, consisting of a pipe and a jacket around it, is the simplest heat exchanger mainly used for small flow rates of fluid. The fluid which is desired to be heated or cooled flows inside the pipe, while the other fluid flows in the jacket. Heat is exchanged from hot fluid to […]
Approximately 70-80% of the heat exchanger market is held by the shell-and-tube type heat exchanger. It is largely favored due to its long performance history, relative simplicity, and its wide temperature and pressure design ranges. In essence, a shell-and-tube exchanger is a pressure vessel with many tubes inside. One process fluid flow through...
Heat exchangers are typically classified according to flow arrangement and type of construction. In the first classification, flow can be counter current or co current (also called parallel). Heat exchangers can also be classified based on their configuration as tubular, plate and shell & tube heat exchangers. The tubular heat exchanger,...
A heat exchanger is an apparatus that is used for heat recovery that means it is used to transfer heat from two fluids. The difference between a heat exchanger and condenser is the purpose of the state change of the substance (liquid or vapors). Heat Interchanger: The use of heat interchangers, either as an aid […]
Generator Heat Exchanger Overview: Generator heat exchangers are understands the degradation of steam generator heat exchanger tubing, both mechanical and corrosion modes, which has resulted in extensive repairs and the replacements around the world. The variety of degradation modes challenges the integrity of tubing and, therefore, the stations’...
