Optimisation of high-efficiency combined heat and power systems for distributed generation

Maria Anna Chatzopoulou, Christos N. Markides, Imperial College London, Engineering And Physical Sciences Research Council, European Institute Of Innovation And Technology
2019
Distributed combined heat and power (CHP) systems have the potential to cover a significant amount of the global energy requirements for power, and heating.  ...  In CHP-ICE systems, more than 55% of the energy input is transferred as heat in the exhaust-gas stream and the jacket water cooling circuit.  ...  Another important area of research identified is the design of real-time controllers, which will be capable of monitoring the heat-source variations, and send signals to the ORC engine, to adjust its operation  ...
