Introduction
Solar chimney technology?
Electricity power generating method
Warm air of a large solar collector up drafting through tall chimney.
Floating Solar Chimney?
Solar chimney with successive balloon tubes.
Filled with a lighter than air gas.
Principle of operation
Greenhouse effect
Absorption of short wavelength of visible light by a transperant medium.
Longer wavelength of infrared re-rediation.
Leeds to heating and resultant higher temperature.
Components of a FSC
The Solar Collector- large open greenhouse with transparent roof
The Floating Solar Chimney (FSC)-
Tall fabric cylinder
warm air of greenhouse is up-drafting.
The Turbo-Generators -set of air turbines geared to electric generators
Generators
Synchronous generators have a large number of pole pairs.
Generated frequency is equal to grid frequency.
Gear box used to limit the generated frequency proportional to grid frequency.
Advantages
They can replace conventional fuel consuming Power Plants.
Low investment risk
environmental friendly reliable, cost competitive
sustainable development and global warming elimination
Feed in tariffs grants and tax benefits
The primary materials of the SAEPs are low cost or recyclable
The SAEPs have long operating life
