LEADERSHIP AND QUALITY IN THE PUBLIC SECTOR

Shown the possibility of using ORC technology to transform low temperature heat source into electricity. Applying ORC CHP to be getting heat and electricity from a single heat source. A review is given ORC manufacturers with ranges of power, heat source, temperature levels and used working fluid. As the working fluid plays a key role in the ORC system the generalized methodology of choice of working fluid is given. The comparison of the most commonly used working fluid through their influence on the thermodynamic or exergy efficiency of the ORC process is conducted, but also the environment and human health consequences are taken into consideration. It has been shown that the ORC system can be applied in small communities or industrial plants that have a sufficient amount of biomass to meet its demand for electricity and thermal energy.
