- These are especially surface condensers used in power industry as part of a standard closed steam cycle in power plants (boiler - turbine - condenser - boiler ...). In surface condensers there is no contact between the cooling water and steam; in principle they are tubular heat exchangers with straight tubes. Downstream of the turbine in the condenser the condensing heat of steam is transferred to the cooling water and steam changes into condensed fluid - water, which is pumped back into boiler. Phase transition from steam to water in the condenser contributes to the expansion of the steam in the turbine thus affecting its efficiency.
- By design we distinguish between radial condensers where the turbine is located on the floor level above the condenser with top steam inlet and axial ones where the turbine is on the same level as the condenser with a side steam inlet into the condenser.
- The condenser shell is usually made of carbon steel. The inlet and outlet cooling water chamber is most typically made of carbon steel, in specific applications dedicated material is used, e.g. resistant to salt water where sea water is used for cooling. Heat transfer tubes are made in material variants of corrosion resistant steel, titanium and less often brass.
Dimensions of heat transfer surfaces produced in PBS INDUSTRY range from 650 to 4,500 square metres. The weight range is from 20 to 125 metric tons. We supply these significant products to the world’s leading players in the power industry. Our company has been involved in manufacture of these types of equipment for more than fifteen years having delivered around 35 different types of equipment to our customers.
