Abstract:
In the paper the application of ORC in the installation of heat recovery from the power unit is described. Presented works form a part of the national strategic project underway for one year. The analysis of possible configurations of waste recovery is done in several stages. In the first stage it is assumed that the ORC evaporator is supplied with hot water of temperature equal to 80 oC. Such temperature of working medium is coming from the energy conversion of all identified and possible to use waste energy sources in the power plant. Next, attention is focused on the possibility of increasing the upper temperature of the cycle. That could be done, for example by incorporation of absorption heat pumps or solar collectors in the cycle. Next, attention is focused on the possibility of designing the exhaust gas-working fluid heat exchanger where the exergetic losses would be limited and therefore the efficiency would increase. Some preliminary tests of the prototype of such heat exchanger have been conducted in the laboratory showing promising results.
