| Summary: | Non renewable energy resources will soon be exhausted, consequently leading
to the world energy crisis. As this happens, non renewable e
nergy is being replaced by
renewable energy resources. This work presents the design, fabrication and
performance analysis of a solar chimney power generator. Solar Chimney power
generator utilize hot air rise concept in power generation. The design consis
ts of a
chimney tower built on top of a circular
solar collector
. These two structures are
connected via a curved cave called the chimney support.
Below t
he
solar collector
lays
the heat absorber plates and water tubes for heat storage which is later used
for night
operation. An air flow director is placed below the chimney to direct the air upward
which then turns the electric generator in the chimney. Solar chimney is designed to
generate electric power 24 hours a day based on the hot air rise concept. Th
e overall
performance of the solar chimney is studied in this project. In this project, the
fabrication method was employed. The performance of a solar chimney is dependent
on the sun radiation, solar collector’s size, collector glass’s transparency and gr
ound
type. The night operation performance is influenced by the ground properties and
water tube size. The fabrication of solar chimney involves manufacturing a structure
of 4.2m in diameter and 3m in height. With this prototype design it is hope 1W of
ene
rgy will be obtained. |
