Abstract:
This paper presents a concept and a test stand of the hybrid micro power plant. The plant has been referred to as geo-bio and is of a binary type in the thermodynamic sense. The system consists of two cycles: an upper steam cycle using energy from the combustion of biomass and a geothermal energy assisted bottom cycle - an ORC (Organic Rankine Cycle) using waste heat from the upper cycle. The micro power plant is composed of two turbines - a steam turbine of the upper cycle and an ORC turbine of the bottom cycle. A single Curtis stage (in the radial arrangement) is used as the steam turbine. The ORC turbine is made as a hermetic turboset unit. Heat exchangers are of a plate type. The experimental results show a technical applicability of the concept. The paper presents some technical details and selected results of the tests.
