Abstract:
The paper presents the construction and the first results of analyzes performed on the newly built micro CHP ORC power plant test stand. The research covers initial start-up tests. This test stand has been built at the Institute of Fluid-Flow Machinery, Polish Academy of Sciences in Gdansk, Poland. It is a universal test stand where it is possible to examine among others micro turbines of various designs operating on a low boiling agent. The test stand is simulating Micro CHP based on ORC technology cogeneration unit producing electricity and heat as hot water up to 55C (design conditions) applicable for low temperature heating (floor or wall heating systems). The supersonic turbine with a capacity of up to 3 [kW] was installed on the test stand. The HFE 7100 is a working medium in this system. This article briefly describes the construction of laboratory test stand, it is composed of turbine, pump, heat exchangers, regenerative heat exchanger and a set of sensors. The paper presents the results of experimental studies, for example graphs showing variations in temperature and in pressure at various measurement points on the test stand. The article also includes graphs of power generated by ORC turbine as a function of available pressure difference.
