When the multiaward winning Dahanu Thermal Power Station needed to retrofit a new energy efficient ventilation solution, the smart choice came down to EcoPower® EP600 from CSR Bradford Ventilation.
The 500 MW coal fired power station located on the west coast of India has taken active steps to reduce its environmental impact since opening in 1996. As part of its energy conservation measures, the plant operator Reliance Energy undertook an upgrade of the exhaust ventilation system in the Turbine Generator Hall by replacing the existing electric axial exhaust fans.
The original fans were unreliable, required frequent maintenance and consumed excessive amounts of electricity. Reliance Energy also recognised the benefit of a hybrid ventilator that is able to work consistently for a long time; with or without a power supply.
Installing EcoPower® ventilators delivered numerous benefits to the project such as reducing energy consumption by over 97% and achieving a maximum energy consumption of 116W per unit, typically consuming 90 - 100W.
One challenge for this project was that the generator hall roof had existing penetrations for the original exhaust fans. Custom transition pieces were constructed to ensure weatherproofing and eliminate the need for new penetrations, or sealing of the existing openings.
