Steam Condensers - SlideShare Steam Condensers 1. Steam Condensers 3/28/2015 1Footer Text 2. Definition: Condenser is a device in which steam is condensed to water at a pressure less than atmosphere. Condensation can be done by removing heat from exhaust steam using circulating cooling water. During condensation, the working substance changes its phase from vapour to liquid and rejects latent heat. The exhaust pressure in ...

Notes on Steam Surface Condensers - ME Mechanical In surface condensers there is no mixing of exhaust steam and cooling water. The condensate can be re-used in the boiler: In surface condenser even impure water can be used for cooling purpose whereas in jet condensers cooling water must be pure.
Surface Steam Condenser | Electrical4U In two flow steam condenser, cooling water travels twice once from inlet-water box to end water box and once from end water box to outlet water box. Two flow condenser is already discussed. By providing more and more partitions in the water boxes, surface condenser can be made multi flow condenser like, 4 flow, 6 flow etc.
TABLE OF CONTENTS - Graham The function of a surface condenser is to create the lowest possible turbine or process operating back pressure while condensing steam. The condensate generated is usually recirculated back into the boiler and reused. Both of these operations are accomplished at the best efficiency consistent with the ever-present problem of economy.
Experiments on Evaporation & Surface Area | Sciencing Molecules contained in a liquid evaporate from the surface area. This means that the larger the surface area, the faster the rate of evaporation. Test this by putting water into two different containers. Use one that has a diameter of a 3 or 4 inches, such as a glass, and another that has a diameter of 8 to 10 inches, such as a bowl.
Surface condenser - Wikipedia A surface condenser is a commonly used term for a water-cooled shell and tube heat exchanger installed to condense exhaust steam from a steam turbine in thermal power stations. These condensers are heat exchangers which convert steam from its gaseous to its liquid state at a pressure below atmospheric pressure. Where cooling water is in short ...

Heat Engines vol 2 The most common type is a surface condenser which has the great advantage that the condensate (condensed steam) is not thrown to waste but is returned to the boiler through feed water system. A jet condenser is a much simpler* and less costly apparatus than a surface condenser. The jet condenser should be installed where a cheap source
Steam Surface Condenser Question & Answers STEAM SURFACE CONDENSER Questiom & Answers. What is a jet condenser? Answers: It is a direct contact heat exchanger in which steam to be condensed comes into direct contact with the cooling water (cold condensate) which is usually introduced in the form of a spray from a jet.

vacuum, surface condensers, process industry, processing ... Tube bundle of a surface condenser. In surface condensers there is no direct contact between the vapours to be condensed and the cooling water. The condensation heat is removed via the heat-conducting walls. Therefore, the temperature difference between condensation and cooling water is greater than that in the mixing-type condensation method.
Steam Surface Condenser Question & Answers What is a surface condenser? A device for condensing steam in which the steam and the water do not come in contact with each other.
