Abstract
A sun tracking solar energy boiler comprising a solar radiation collector and tracking assembly for collecting and focusing solar radiation upon a surface maintained precisely normal to its direction of incidence, in combination with boiler means comprising a preheat tank and steam pressure tank arrangement to maintain a predetermined water level in boiler tubes. The collector and tracking system is provided with means for tracking the sun in its hourly travel from sunrise to sunset, and means is provided for matching seasonal changes of the sun from the summer maximum height to the winter maximum dip with use of a completely automatic apparatus requiring a minimum of manual attention. Means are provided to prevent or remove any lens obscuration, and liquids other than water can be successfully used in the boiler means. Properly adjusted, the system is operable anywhere on earth with a latitude of 5 degrees or higher; special adaptation can be made for locations nearer the equator. The system generates electric power during the period of peak electrical power demand, and is thereby complementary with systems adapted to provide uniform power generation throughout the day and night.
