DESCRIPTION:
BRIEF SUMMARY
The present invention relates an apparatus and method for producing working medium for supply to an engine of a power installation. More especially the invention relates to the area of power-plant engineering of electricity-generating installations for the transformation of low-potential and high-potential thermal energy into mechanical and electrical energy, and also in the area of a means of preparation of a working medium for such installations.
TECHNICAL BACKGROUND
There exists an electricity-generating installation containing a high-potential heat source. The installation has a closed circuit with an intermediate heat-transfer medium, a power turbine, heat-exchangers for heating and cooling the working medium. Patent USSR No. 70147, Int. class. F03G7/00, publ. 1948 applies.
There also exists an electricity-generating installation containing a turbine for driving a load, a cooler, a circulating pump and two or more chambers for preparing the working medium, all of the above connected by means of pipelines. The chambers are connected to the turbine and have a heater, a separator and sealing devices at the outlet. The circulation pump is connected to the cooler and to each of the chambers to form a circuit for the circulation of liquid. Patent USSR No. 1170180, Int. class FO125/00, publ. 1985 applies.
There exists a means for the preparation of the working medium of an electricity-generating installation, consisting in the filling of an intermediate heat transfer medium circuit with a volatile liquid and its subsequent evaporation in an heat-exchanger by air compressed in an compressor and the supply of the vapour to the turbine. Patent USSR No. 70147, Int. class F03G7/00, publ. 1948 applies.
There also exists a means for the preparation of the working medium of an electricity-generating installation, including the filling of one or more chambers with a liquid, the introduction into one of the chambers of an additional component and the raising of its pressure, the heating of the working medium formed in it and, following the supply of the working medium to the turbine, the performance of these operations in another chamber. Patent USSR No. 1170180, Int. class F01K25/00, publ. 1985 applies.
Further, U.S. Pat. No. 3943719 discloses apparatus for supplying working medium to an engine (e.g. turbine), this apparatus comprising generating means for producing working medium and delivery means for supplying said working medium to an engine. In particular the generating means comprises reactor means for the formation of a compoung (i.e. hydride) from which the working medium (i.e. Hydrogen) is obtained, while storage means are provided for holding said compound formed by said reactor means, said delivery means including control means for controlled delivery of working medium from the storage means to the engine.
According to one aspect of the present invention there is provided apparatus for supplying working medium for a gas expansion engine comprising generating means for producing working medium, storage means for the working medium, and delivery means for supplying the working medium to an engine from the storage means, the delivery means including control means for controlled delivery of the working medium from the storage means to the engine wherein the generating means comprises reactor means arranged and adapted for the formation of a gas-hydrate from which the working medium for the engine is obtained, the storage means holding the gas hydrate formed by the reactor means, and a liquid recirculation circuit is provided for recycling liquid discharged from the reactor means back to the reactor means, the recirculation circuit including a recirculating pump and a heat-exchanger. The method in particular using water condensate from a steam turbo-generator plant for the production of the gas hydrate (with a further component) in a reaction chamber, the gas hydrate so produced being stored in suitable storage means in readiness for the formation of the working medium.
