Patent ID: 8402762

Claim:
A method of generating electric energy from recovered heat during an industrial process that uses steam as a means of transferring energy comprising the following steps: a) generating a first saturated steam in a first heat exchanger heated by a first source of recovered heat; b) feeding said first saturated steam into a first steam turbine generator, said first steam turbine generator outputting a first exhaust steam; c) removing moisture from said first exhaust steam with a moisture separator, the moisture separator outputting a dried exhaust steam; d) superheating said dried exhaust steam from step c in a reheater heat exchanger with a reheater heat source, said reheater heat exchanger outputting a superheated exhaust steam; e) feeding said superheated exhaust steam into a second steam turbine generator; f) generating a second saturated steam in a second heat exchanger heated by a second source of recovered heat and wherein said reheater heat source comprises said second saturated steam; and g) generating a third saturated steam in a third heat exchanger heated by a third source of recovered heat and mixing said third saturated steam with said dried exhaust steam thereby producing a mixed exhaust steam, said superheating comprising superheating said mixed exhaust steam and said feeding comprising feeding said superheated mixed exhaust steam into said second steam turbine generator.
