Abstract:
1. A waste heat vapor generator for supplying organic motive fluid vapor to a turbogenerator, comprising: an inlet connected to a source of waste heat gases and 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, an organic motive fluid preheater in said chamber, an organic motive fluid provided in said preheater and flowing in heat exchange relation with said waste heat gases in said chamber, whereby organic motive fluid in said organic motive preheater receives heat from the waste heat gases, an organic motive fluid boiler, the organic motive fluid being provided in said boiler and flowing in heat exchange relation with said waste heat gases, wherein organic motive fluid in said organic motive boiler receives heat from the waste heat gases, and an organic motive fluid superheater, the organic motive fluid being provided in said superheater and flowing in heat exchange relation with said waste heat gases in said chamber, whereby organic motive fluid in said organic motive superheater receives heat from the waste heat gases, wherein said organic motive fluid boiler is connected to said preheater to receive preheated organic motive fluid from the preheater and is positioned upstream to said organic motive fluid superheater in the direction of the flow of the waste heat gases, and said organic motive fluid superheater is positioned upstream to said organic motive fluid preheater in the direction of the flow of the waste heat gases from the inlet to the outlet.
