Cost Effective Small Scale Orc Systems for Power Recovery from Low Grade Heat Sources

The growing need to recover power from low grade heat sources, has led to a review of the possibilities for producing systems for cost effective power production at outputs as little as 20-50kWe. It is shown that by utilizing the full potential of screw expanders instead of turbines, it is possible to produce Organic Rankine Cycle (ORC) systems at these outputs, which can be installed for a cos...

Low-Grade Waste Heat Recovery for Power Production using an Absorption-Rankine Cycle

An investigation of heat recovery for power generation using an absorption-Rankine cycle with a low temperature waste heat source was conducted. In such a cycle, the condenser and boiler of a conventional Rankine system are replaced with an absorber and desorber. A recuperative solution heat exchanger is also incorporated between the absorber and desorber to minimize the external heat input. An...

Methods of Increasing Net Work Output of Organic Rankine Cycles for Low-Grade Waste Heat Recovery

In heat engine design, the usual objective is to maximize thermal efficiency. However, for heat engines applied to waste heat recovery, an appropriate objective is to maximize power production by converting as much of the waste heat as possible into work. An organic Rankine cycle (ORC) is particularly well-suited to waste heat recovery because of its compactness relative to a steam Rankine cycl...
