Service

Steam under vacuum in thermal power plants.

   Finned Tubes    Options

'L' type single foot fins for normal environment.

'LL' type overlapped fins for dusty environment which can be cleaned with mild water pressure jet.

Extruded bi-metallic fins for severe dusty environment like cement plants, which can be removed with high pressure water jet cleaning.

   Headers

Welded 'D' type .

   Construction

A- Frame type with primary and secondary section tube bundle in each cell having one fan.
Fans are large diameter gearbox driven operating in forced draft mode.

   Scope of Supply

• Tube bundles
• Fans either in FRP or aluminium construction driven by gear box
• A-frame mounting structure.
• Wind wall for arresting cross winds.
• Steam duct from turbine exhaust frame to condenser with expansion bellows.
• 2 x 100% holding ejectors and 1 x 100% hogging ejector.
• Condensate and hotwell drain tanks.
• Condensate extraction pumps.
• Hotwell pumps.
• Control instrumentation.
• Piping from the condenser upto ejector.

   Energy Saving

Better operational flexibility can be achieved depending upon the variation of ambient temperature and plant load demand. Energy can be effectively conserved through fan control systems. A cheaper but less effective method is by using two speed fan. More effective energy saving can be achieved by using variable speed drive for the AC motors.
