Abstract:

In 0rder to investigate the actual running process of all kinds of heat exchangers with great energy waste eaused bv the fl0uling resistance,the economy performance of two condensers respectively with rifled tubes and smooth tubes are analyzed and compared,aiming to determine whether the energy consumption of the system can be decrleased by selecting different tubes to improve the heat exchange perform ance of the condenser.The fouling and resistanee eharacteristies 0f the heat exchange tube were both taken into account during the analyses. The result shows that rined tubes eannot always enhance the economy perform ance of the condenser,and there are critical ve-l0eitv and eritieal time in the condenser.Thus,a theoretical basis and some references were given to the design and economical operation of the condenser.

Key words: fouling, condenser, rifled tube, economy perform ance
