The article deals with a description of results from research and development of the cantilever micro-turbine designed for the ORC power plants. The experimental turbine stage and used numerical models are briefly described. In the first part the comparison of measured and CFD results is presented. The second part deals with an investigation of the outlet geometry influence on the turbine working parameters. The results are relevant for next studies in the research and development process.

“…Siloxanes are used as working fluids in commercial biomass Rankine cycles, [30]. In [31] the design of a small radial turbine (of about 10 kW) with a siloxane is discussed. The evaluated turbine efficiency is said to be about 0.76, at a rotational speed of 31,000 rpm.…”

Small-CHP (Combined Heat and Power) systems are generally considered a valuable technological option to the conventional boilers, in a technology developed context. If small-CHP systems are associated with the use of renewable energies (biomass, for example) they could play an important role in distributed generation even in developing countries or, in any case, where there are no extensive electricity networks. Traditionally the considered heat engines for micro-or mini-CHP are: the gas engine, the gas turbine (with internal combustion), the steam engine, engine working according to the Stirling and to the Rankine cycles, the last with organic fluids. In principle, also fuel cells could be used. In this paper, we focus on small size Rankine cycles (10-15 kW) with organic working fluids. The assumed heat source is hot combustion gases at high temperature (900-950 • C) and we assume to use only single stages axial turbines. The need to work at high temperatures, limits the choice of the right organic working fluids. The calculation results show the limitation in the performances of simple cycles and suggest the opportunity to resort to complex (binary) cycle configurations to achieve high net conversion efficiencies (15-16%).

“…Other plants of this kind are the ORCHID at TU Delft [11], the CLOWT at Muenster University of Applied Sciences [12] and the dense-gas blowdown facility at Imperial College London [13]. Several turbine-fitted facilities such as the LUT micro-ORC test rig at Lappeenranta -Lahti University of Technology [14] exist too. The ORCHID at TU Delft is designed to also operate in this configuration.…”
