ADVANTAGES

CONCLUSION

REFERENCE


3/20

Solar power tower is a type of power plant

Early 1980s power towers have been fielded inRussia,Italy.Spain,Japan and United States

Power towers are commercially less mature thanparabolic trough system

Thermal energy collected at the receiver was used togenerate steam directly to drive a turbine generator

Main power towers are Solar One & Solar Two

6/20


7/20

Operated from 1982 to 1988

Worlds largest power tower plant

Main parts are :

Heliostat Receiver

Steam generator

Steam turbine

Condenser Two tanks for cold and hot storage


8/20

Storage mediums are rocks/oil

The heliostats consisted of 1818 heliostats of

39.3m2 reflective area

Power output is 10MW

The storage system was complex and

thermodynamically inefficient

Solar one successfully demonstrated power towertechnology


9/20

Ability to generate 10MW for eight hours a day at

summer and four hours a day at winter

Feasibility of generating power with a power tower


10/20

Storage medium is nitrate salt(60% sodium nitrate,

40% potassium nitrate)

Reduce technical & risks of power tower

Designed & built by Boeings Rockedyne division

Panels form in cylindrical shell surrounding piping,

structural supports & control equipment


11/20

Tubes are coated with Pyromark paint

Receiver absorbs maximum amount of sunlight

Reduce heat loss due to convection & radiation

Consists of 875000 liter storage tank

Stainless steel and carbon steel are used for the

construction of hot and cold tanks


12/20

Thermal capacity is 110MWh

Salt in the cold tank is pumped with multi- stage

centrifugal pumps up the tower to the receiver


13/20

COMMERCIAL APPLICATIONS

Planning and designing of utility size power plant

Helpful in developing commercially viable power

plants


14/20

NOVEL APPLICATIONS Use of pit minesstadium seating helps over come

blocking constriant

A pit power combines solar power tower & aero-electric power tower

Collect water having been dug below the water table

Re-purposing of a pit mine helps the reusing mine

infrastructure


15/20

Increase the capacity factor


16/20

Inexpensive and efficient energy storage system

Increasing the monetary value of electricity

No hazardous gaseous or liquid emissions are

released

Condamination of soil due to salt not occur


17/20

Solar power towers are most efficient plant used

for power production

Efficient storage system

Pollution free
