Abstract
This invention relates to a method of condensing and energy recovery within a thermal power plant using the Venturi effect and gas stored under hydrostatic pressure and to an energy storage system using the method in a hydrogen and oxygen combusting turbine, where the hydrogen and oxygen gasses are produced by water electrolysis and hydrostatically pressurized and stored.
Claims11
A method of energy recovery for a thermal power plant, said method comprising the following steps:
- (a) a first working fluid delivering energy to a main power generating turbine then passes through a heat exchanger means in a Venturi condenser whereupon at least some of the energy remaining is extracted, and at least some of the first working fluid condenses to a liquid state;
- (b) a second working fluid enters one or more Venturi tubes in the Venturi condenser at elevated pressure, the second working fluid cooling and decreasing in pressure as it passes through the one or more Venturi tubes the second working fluid absorbing thermal energy from the first working fluid in the heat exchanger means in the Venturi condenser;
- (c) a reduced volume of the first working fluid causing a decreased pressure downstream of the main power generating turbine which increases flow of the first working fluid through the main power generating turbine;
- (d) the second working fluid after absorbing thermal energy in the heat exchanger means passing through a second power generating turbine where energy is extracted.

A power generating system comprising a thermal power plant including:
- (a) a vaporiser means for vaporising a first working fluid, a conduit means for conducting said (vaporised) first working fluid to a main power generating turbine for extracting energy from the first working fluid;
- (b) conduit means for taking the first working fluid exiting the main power turbine to a Venturi condenser, the first working fluid passing through heat exchanger means in the Venturi condenser to transfer heat to a second working fluid;
- (c) the Venturi condenser, provided with an inlet for receiving the second working fluid at elevated pressure, an inlet leading to one or more Venturi tubes, the one or more Venturi tubes having a converging inlet portion, a straight constricted portion and a diverging outlet portion, a further heat exchanger means surrounding the diverging outlet portion;
- (d) a second power turbine for extracting energy from the second working fluid exiting the one or more Venturi tubes;
- (e) conduit means for returning said first working fluid to the vaporising means;
- (f) pumping means for pressurising and returning said first working fluid to the vaporising means;
- (g) pump means for optionally pumping the second working fluid to a hydrostatically pressurised storage unit;
- (h) storage means for storing said second working fluid in gaseous state under hydrostatic pressure;
- and
- (i) conduit means for conducting the second working fluid from said storage means to the inlet of the Venturi condenser.
