The photograph shows only two concentrators to explain the concept while actually three to five concentrators will be used in field depending on site conditions.
Salient features of the new system are:
- Multiple reflectors with square shape in plan.
- Compact design as the shape is switched over to square from round.
- 100% aperture area available year-round. (Established Scheffler technology gives approximately 60% average aperture area.)
- Single axis fixed speed daily automatic tracking eliminates need of sensors and complicated hardware. Tracking system is easy to operate and maintain. Seasonal tracking is manual to be set once in 3-4 days.
- Photograph shows two reflectors of 6.25 m2 each delivering 2000 to 2500 Watts per reflector. Trials on larger sizes of 10 m2 and 15 m2 square and rectangular dishes are to be conducted before standardization.
- Expected cost of this system installation after commercialization is around Rs. 15000/- per kW installation with payback period of less than 30 months without subsidies. This is very comfortable for Industries.
- Performance: An air working temperature of 250 °C (482 °F) is comfortably achieved. Maximum temperature attained for air is about 400 °C (752 °F). Thermic fluid can be comfortably used with second stage heat exchanger for steam generation.
