Steam Surface Condenser
The Steam Surface condenser is a critical component of both the traditional coal fired power plant and the new generation cogeneration and combined cycle power plants.
Main duties of any Surface Condenser are to convert the exhaust steam from its gaseous to its liquid state at certain under atmospheric pressure, and also, to release non-condensable presented in the steam cycle, together with
vacuum unit.
Jet Flow designs and economically sized condenser suitable for smaller turbine ratings under 100 MW. The circular configuration is compact for easy shipping and maintains the level of quality afforded
all of our condenser designs.
All of Jet Flow’s Surface Condensers are designed and built to the Heat Exchange Institute latest Standards.We also strive to meet all of our client’s project specific requirements.
Our Condenser design can incorporate enhanced deaeration systems, and or a variety of turbine exhaust options including Axial and Top steam inlet design, which can assist greatly in improving plant layouts. We continually
address and refine these and other considerations associated with circular designs where space is at a premium.
Jet Flow Surface Condensers are fabricated in-house state of the art fabrication facilities located
in Ahmedabad. All of the fabrication facilities are according toASMEcode and an impeccable reputation for quality fabrication and on time delivery.
Our Surface Condensers feature high overall heat transfer coefficient
(which result in smaller heat transfer areas and thus optimal use of the available space) and extremely low oxygen concentrations in the condensate. They are designed to stand up to turbine and steam generator overloads
and to variations in cooling water temperature at different times of the year.
Jet Flow Surface Condenser highlights:
- Effective steam distribution within tube nest
- Uniform distribution of heat loading
- Effective collection and removal of noncondensable gases
- Negligible condensate subooling
- Minimized condensate inundation
- Lower velocity fluctuation
- Efficient air cooling section
- Effective de-aeration performance
- One orTwo passes.
- Down Flow, Axial flow or side inlet design.
- 4 to 6 months delivery.
- Available for all type ofTurbines.
Air cooling zone is provided in the coolest part of the condenser, which minimise the carry overof the steam to the ejector vacuum system alongwith the non condensable gases.
Geothermal Steam Condensers:
Jet
Flow has many years of experience designing vacuum Condensers with high non-condensable loads. Since Geothermal steam is highly corrosive and contains large amounts of non-condensable gases, the design and fabrication of
Geothermal Steam Condensers is radically different than conventional power plant condensers. Special attention to be given on reduced overall heat transfer rates and LMTD due to high amount of non condensable gases, pressure
drop, sub-cooling, flow path for venting large volumes and material selection to prevent corrosion. Associated vacuum system is Multi stage Steam Ejectors with direct OR in-direct type inter condensers.
