Abstract
The present invention provides an organic Rankine cycle power system, which comprises means for superheating vaporized organic motive fluid, an organic turbine module coupled to a generator, and a first pipe through which superheated organic motive fluid is supplied to the turbine, wherein the superheating means is a set of coils through which the vaporized organic motive fluid flows and which is in direct heat exchanger relation with waste heat gases.
Claims15
A waste heat vapor generator for supplying vapor to a turbogenerator, comprising an inlet through which waste heat gases are introduced, an outlet from which heat depleted waste heat gases are discharged, a chamber interposed between said inlet and said outlet through which said waste gases flow, and a preheater, boiler, and superheater through which organic motive fluid flows in heat exchanger relation with said waste heat gases, said preheater and superheater being housed in said chamber, wherein said boiler is positioned upstream to said superheater, and said superheater is positioned upstream to said preheater.
An organic Rankine cycle power system, comprising means for superheating vaporized organic motive fluid, an organic turbine module coupled to a generator, and a first pipe through which superheated organic motive fluid is supplied to said turbine, wherein said superheating means is a set of coils through which the vaporized organic motive fluid flows and which is in direct heat exchanger relation with waste heat gases.
The power system according to 9 including a cycle pump for supplying liquid motive fluid from said condenser to said preheater in accordance with the level of the liquid in said boiler.
A desuperheating method, comprising the steps of vaporizing an organic motive fluid, superheating said vaporized fluid, delivering said superheated fluid to a turbogenerator to generate electricity, and mixing liquid phase motive fluid with said vaporized fluid in response to a temperature of said superheated fluid which is above a predetermined level.
