Dump Condenser

Dump Condensers are used to recover large amounts of steam that may otherwise be vented to the atmosphere. During fluctuating steam loads, turbine trip off, turbine start-up, or bypass, the excess steam that would ordinarily be vented can be diverted to a dump condenser. Dump Condensers may also be used for process plants when upset demand conditions occur.
A dump condenser is required when the steam consumption needs to be drastically reduced in a very short period of time and when the boiler cannot follow this variation.

Features :

  • Water-cooled Dump Condensers
  • Fabrication and design typically to Heat Exchange Institute
  • Standard (HEI), ASME Code, and can include TEMA, Seismic
  • Codes, and other specifications.

Designs to eliminate excessive vibrations and water hammer Standard materials are carbon steel with stainless steel tubes. Special materials are available for severe duty or other applications.
Dump Condenser can be furnished as a system which may consist of Steam Pressure/Temperature Reducing Station and Condensate Recovery System which includes Level Controls, Condensate Pumps, and Electrical Control Panel for automaticoperation.

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.

Gland Vent Condenser (Gland Sealing Systems)

Gland seal systems very important to main and auxiliary turbines.Turbine shafts must exit their casings in order to couple up or connect with the unit that the turbines drive (reduction gears, pumps, etc.) The main and auxiliary gland seal systems enable the turbine to be sealed where the shaft exits the casing; in effect keeping "air out and steam in."
The purpose of gland seal system is to prevent the leakage of air from the atmosphere into turbine casings and prevent the escape of steam from turbine casings into the atmosphere.
The gland sealing system provides low pressure steam to the turbine gland in the final sets of labyrinth packing. This assists the labyrinth packing in sealing the turbine to prevent the entrance of air into the turbine, which would reduce or destroy the vacuum in the associated condenser. Excess pressure (excess gland seal) is removed by the gland seal unloader.
Since there are times when steam escapes from the seals, a gland exhaust system is provided. The gland exhaust system consists of low pressure piping connected to the gland area between the last two outer sets of labyrinths which receives and prevents steam from escaping to the atmosphere. This system collects the steam and directs it to a condenser for further use in the steam plant.
Most steam turbines have a shaft sealing system which uses carbon rings to isolate the rotor assemblies on both ends with steam injected to prevent air in-leakage in to the turbine. The leakage would reduce turbine efficiency and flow into the condenser downstream of the turbine further reducing system efficiency. This gland steam must be removed by an ejector or exhaust fan to prevent it from flowing back into the turbine.
