Design analysis of turbines for co-generating micro-power plant working in accordance with organic Rankine’s cycle

This paper presents results of a design analysis of turbines for co-generating micro-power plant working in accordance with organic Rankine’s cycle and using biofuel. The heat power range from 25 kW to 100 kW with corresponding available electric power from 2kW to 12kW, was considered. Designs of axial-flow turbines (single-stage and multi-stage ones, also those partially fed), radial-flow and axial-radial -flow ones, were analyzed. Particular variants of the solutions were compared to each other.
