Solar energy is the most available, clean, and inexpensive source of energy among the other renewable sources of energy. This work deals with experimental steady to determent the performance of solar tower steam production for power generation. Designed and fabricated of two shapes of a solar tower, first consist of a central receiver rectangular tank (0.4m*0.6m*1.0m) and 75 heliostat mirrors arranged around it, second consist of a central receiver cylindrical tank (0.5m*1.0m) and 75 heliostat mirrors arranged around it. The central tank was made of galvanized steel. Each heliostat consisted of two (0.5m*0.5m) mirror. The results of this work produce steam at temperature 110oC from first type and 117 oC. Large steam quantity could be obtained when using the cylindrical tank. The results of the work gives good indication for using cylindrical shape of central receiver tank in application of solar energy to produce power in Iraq.
Key word: solar central tower, heliostat, steam generation, concentration system.
