Compound heat pump gas turbine: an approach to energy conservation for process industries
A compound heat pump gas turbine engine is proposed to achieve energy conservation in industrial processes that require cooling or refrigeration as well as electric power and process heat. This novel machine is basically the combination of a reversed cycle Brayton engine driven by a gas tubine, with the two engines having a common compressor. Because of this arrangement, the machine is very compact and should be relatively inexpensive to produce. Also, it can be adapted to a variety of fuels. The thermodynamic cycle and some performance characteristics of the compound engine are presented and the potential of such a machine for a meat packing plant is demonstrated. It was concluded from this study that this engine layout will result in significant reductions in engine cost, compared with systems consisting of separate components for power generation, refrigeration, and process heating. In addition, significant savings in energy consumption may be realized. Furthermore, it appears that engines of this type can be made to meet widely differing specifications as far as the split between process heat refrigeration and shaftpower is concerned. Finally, the engine can be made up of compressors, turbine stages, and heat exchangers of relatively simple design without penalties in economy, because the energy savings are achieved in this type of engine by reduction or complete elimination of waste heat, rather than high efficiencies of engine components. The possible energy savings for the meat packing industry indicate that the compound heat pump gas turbine deserves further study, including its cost, operating expenses, and environmental aspects.
