By participating in the Concentrated Solar Thermal Power Summit in India in the spring of 2011, Aalborg CSP & Sojitz Corporation took the first step towards entering the Indian CSP market.

Now a year later, Aalborg CSP & Sojitz Corporation is looking forward to attending the event again after a year where the need for the advanced Aalborg CSP steam generator technology was boosted which resulted in an order to supply the steam generator for the first 50+MWe parabolic trough plant in India.

First 50+MWe CSP plant in India:
At present, Aalborg CSP is constructing the steam generator for a 50+MWe parabolic trough solar plant for the Godawari project, the first 50+MWe plant to be installed in India.
When the CSP plant is up and running, it will produce superheated steam at 385°C at 104 barg driving a steam turbine producing environmental friendly electricity.
The steam generator unit is on the water/steam side based on natural circulation and on the heat transfer fluid (HTF) side based on limited forced circulation based on ultra-low pressure drop.

Highly improved bankability – long term savings:
”With great focus on the plant economy, the products provided by Aalborg CSP have been able to meet these demands by using technology that ensures savings in the long term”, says sales director and partner at Aalborg CSP Peter Badstue Jensen.
Aalborg CSP’s steam generator design is based on steam boiler technology of header-type, rather than conventional kettle-type heat exchangers. By applying a fully welded coil/header-type instead of the kettle-type steam generator using U-tube design a series of benefits in regard to productivity will improve the overall financial perspective and bankability.
When studying the long term efficiency of the U-tube design, numbers indicate that due to tube leaks the productivity of the system declines throughout the lifetime of the system, as the tube leaks cause the system to stop. Applying a fully welded coil/header-type with 4,5mm thick tubes significantly reduces the need for tube plugging, and thereby reduces the number of stops/downtime throughout the lifetime of the system, in this way improving both productivity, electricity earning and the general payback time of the power plant.
