Use Of Heat Exchangers In Nuclear Power Plants
A heat exchanger is a device that transfers heat from a hot to a cold fluid. It is desirable to increase the temperature of one fluid while cooling another in many engineering applications. A heat exchanger achieves this double action economically. It can be used to cool one petroleum fraction while warming another, to cool air or other gases while compressing them, and to preheat combustion air supplied to boiler furnaces using hot flue gas as a heating medium.
Speaking of Heat Exchangers, specialised boiler tubes are utilised in the proper functioning of such exchangers. SA179tube.com Is one leading Manufacturer, Supplier & Stockist Of Boiler Tubes ST 37 Pipes.
Among other uses, it is used to transfer heat from metals to water in atomic power plants and to reclaim heat energy from the exhaust of a gas turbine by transferring it to compressed air on its way to the combustion chambers. In fossil-fuel and nuclear power plants, gas turbines, heating, air-conditioning, refrigeration, and the chemical industry, heat exchangers are extensively used. When they serve a specific purpose, the devices are given different names. Heat exchangers include boilers, evaporators, superheaters, condensers, and coolers.
As a result of the scale or fouling resistance terms, the design surface of the heat exchanger is increased to maximise heat transfer between cleaning cycles. Shell-and-tube heat exchangers are primarily used in liquid-to-liquid units. Nuclear power plants use liquid-to-liquid heat exchangers for cooling moderators, for instance.There are two main sections of a nuclear heat exchanger: the primary side components consisting of the tube sheet, tube bundle, head, and nozzles, and the secondary side components consisting of the shell, shell baffles, head, and nozzles.
Why Compact Heat Exchangers For Nuclear Plants?
- At first glance compact Heat Exchangers would seem to be the obvious choice
- However, there is much more that needs to be considered
