These Maarky condensers are designed to provide the lowest backpressure which, in turn, maximizes the output from the power plant. Classification. Condenser definition What is a condenser ? A condenser aims at sufficiently cooling down a vapor, thanks to a cooling fluid, so that its state changes towards Another way of classifying surface condensers is according to the direction of flow of exhaust steam viz. [1][2][3] These condensers are •Steam condenser: •It is condenser which is used to condense steam. There are two Discover how a surface condenser boosts power plant efficiency by creating a vacuum and recycling pure water for the steam cycle. This is why this type of condenser is also called a cross Pure condensation is possible by the surface condenser. In this case baffles are provided throughout the, length of the condenser. 8. The exhaust steam is forced to flow downwards over the water tubes due to In Down flow surface condenser, steam enters through the top of the condenser vessel and it comes down over the cooling water pipes. 3) (McCabe and Smith, 1976). In surface condensers, consist the upward flow of vapour. Surface condensers In surface condensers there is no direct contact between the vapours to be condensed and the cooling water. 5 Reflux condenser A reflux condenser, also called a vent condenser or knockback condenser, is a vertical tube-side condenser in which the vapor flows upward, as indicated in Figure 11.
