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.
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,...
Surface Condenser Introduction Tipo surface condenser mainly consists of a cast iron shell. The shell is cylindrical in shape and closed at both end to form a water box. A tube plate is located between each cover head and the shell. A number of water tubes are fixed to the tube plates. The shell is […]
Dynamic scraped surface heat exchanger Fin Cooler Mechanical Compression : – During the compression cycle, the refrigerant passes through four major components within the chiller: the evaporator, the compressor, the condenser, and a flow-metering device such as an expansion valve. The evaporator is the low-temperature (cooling) side of...
