Abstract
A machine designed as a centrifugal compressor is applied as an organic rankine cycle turbine by operating the machine in reverse. In order to accommodate the higher pressures when operating as a turbine, a suitable refrigerant is chosen such that the pressures and temperatures are maintained within established limits. Such an adaptation of existing, relatively inexpensive equipment to an application that may be otherwise uneconomical, allows for the convenient and economical use of energy that would be otherwise lost by waste heat to the atmosphere.
Claims22
A method of using a centrifugal compressor of the type having an impeller, a diffuser and a collector in serial outboard radial flow relationship comprising the steps of:
- introducing a high pressure, high temperature vapor in said collector such that it flows radially inwardly through the diffuser to said impeller, with said diffuser acting as a nozzle;
- allowing said vapor to engage the impeller such that the impeller is caused to rotate as a turbine;
- and
- drivingly connecting said turbine to a generator to cause the generation of electricity.
