Shell and Tube Heat Exchanger
Shell and Tube Heat Exchanger which typically have U-tubes. One fluid runs through the tubes, and another fluid flows over the tubes to transfer heat between the two fluids. They are used to boil water recycled from a surface condenser into steam to drive a turbine to produce power. Most shell-and-tube heat exchangers are either pass designs on the tube side. The Shell and Tube Heat Exchanger can be either liquids or gases on either the shell or the tube side.
Shell and Tube Heat Exchanger order to transfer heat efficiently, a large heat transfer area should be used, leading to the use of many tubes. In this way, waste heat can be put to use. This is an efficient way to conserve energy. The set of tubes is called a tube bundle, and may be composed by several types of tubes: plain, longitudinally finned, etc. Shell and Tube Heat Exchanger refers to the number of times the fluid in the tubes passes through the fluid in the shell. In a single pass heat exchanger, the fluid goes in one end of each tube and out the other.
Shell and Tube Heat Exchanger in steam engine locomotives are typically large, Shell and Tube Heat Exchanger cylindrically-shaped shell-and-tube heat exchangers. In large power plants with steam-driven turbines, shell-and-tube surface condensers are used to condense the exhaust steam exiting the turbine into condensate water which is recycled back to be turned into steam in the steam generator. Heat exchangers with only one phase on each side can be called one-phase or single-phase heat exchangers. Two fluids, of different starting temperatures, flow through the heat exchanger.
Shell and Tube Heat Exchanger through the tubes and the other flows outside the tubes but inside the shell. Heat is transferred from one fluid to the other through the tube walls, either from tube side to shell side or vice versa. Shell and Tube Heat Exchanger can be used to heat a liquid to boil it into a gas , sometimes called boilers, or cool a vapor to condense it into a liquid, with the phase change usually occurring on the shell side.
