초록 ▼

A plurality of independent, closed Rankine cycle power plants, each of which has a vaporizer, is operated by serially applying a medium or low temperature source fluid to the vaporizers of the power plants for producing heat depleted source fluid. A preheater is provided for each vaporizer; and said heat depleted source fluid is applied to all of the preheaters in parallel. The heat depleted source fluid thus serves to heat the operating fluid to the evaporization temperature, while the source fluid applied to the vaporizers supplies the latent heat of vaporization to the operating fluid of the power plant. The present invention is advantageous, as compared to a conventional cascaded power plant of the type described, because the temperature drop of the source fluid can be increased without reducing the efficiency. Alternatively, the temperature drop can be maintained but the efficiency can be increased. In either case, the power produced by the power plant according to the present invention is increased.

대표청구항 ▼

A power plant operating on a source of low or medium temperature fluid comprising: (a) a plurality of closed Rankine cycle power plant modules each having a vaporizer associated therewith responsive to source fluid for converting operating fluid of the power plant modules to vapor, said modules being arranged in a plurality of levels, each level comprising a plurality of modules; (b) means for applying source fluid in parallel to each vaporizer in a level to produce heat depleted source fluid, means for applying heat depleted source fluid from a level to each vaporizer in parallel in the succeeding level; (c) a preheater associated with each vaporizer for preheating operating fluid that is vaporized in the associated vaporizer; and (d) means for applying heat depleted source fluid from the lowest level to all of the preheaters in parallel.
