Abstract
A system for the generation of electrical power using a solar collector that heats water using solar energy. The heated water is stored in a first tank. A vessel is connected to the first tank through a pipe and includes a headspace within which the heated water is sprayed to thereby generate steam. The headspace pressure is lower than atmospheric pressure and the water not converted to steam is collected in a pool at the bottom of the vessel to be fed back into the first tank. The steam is fed to a partial admission turbine that drives an electrical generator.
Claims5
A system for the generation of electrical power including:
- a solar collector for heating water using solar energy, the heated water stored in a first tank;
- a vessel connected to the first tank through a first pipe and having a headspace within which the heated water is sprayed to thereby generate steam, a headspace pressure being lower than atmospheric pressure, the water not converted to steam collecting in a pool at a bottom of the vessel;
- a first pump pumping the water from the pool and into the first tank through a second pipe;
- a third pipe piping the steam to a partial admission turbine;
- a condenser located at a bottom of the turbine including a plurality of water outlets to spray water from a second tank into the condenser to condense the remaining steam into water;
- a second pump that pumps the water from the bottom of the partial admission turbine through a fourth pipe into the second tank;
- wherein a flow rate of the water through the first pipe is at least initially smaller than a flow rate through the second pipe thereby causing a reduction in the pressure in the headspace;
- and
- wherein steam drives the partial admission turbine which drives an electrical generator.
