Abstract:
During recent years the research activity in the area of the ORC power plants has been growing also in the Polish scientific institutions. This is motivated especially by the need to utilize low and moderate temperature heat sources of renewable origin like geothermal water, biomass or the sun collectors. The research work is being carried out at the Polish Academy of Science, Institute of Turbomachinery in Gdansk, at the Technical Universities in Wroclaw, Gdansk and Lodz, and at the West Pomeranian University of Technology in Szczecin. Covered research problems refer in particular to the question of the energy and exergy effectiveness of the single cycle ORC power plant, as well as to the question of their effectiveness improvement by means of application of the evaporators with an internal working fluid circulation. Experimental work is carried out at the West Pomeranian University of Technology on the first in Poland fully operational small ORC power plant built by the Turboservice Company of Lodz. The research on the area of the ORC power plant applications is further extended to cover utilization of the waste heat encountered in various industrial branches like chemical, cement or ceramic plants. The works published by the Polish scientific institutions refer also to some other types of the power plant solutions. They include double and triple cycle power plant schemes with sequential supply of the economizers and evaporators, as well as power plants for which the conventional saturated or superheated steam cycle functions as the upper temperature cycle. On the basis of the works published by the institutions quoted above the most interesting, valuable and novel research results will be presented.
