Abstract
The article presents basic results of the design analysis of a combined gas-vapour micro power plant with a waste-heat boiler without exhaust reheat, working in the vapour section in the Organic Rankine Cycle (ORC) system. The analysis concerned working media most frequently used in those types of power plants and planned to be used in future. The object of the analysis was a micro power plant with a 30 kW gas (air) turbine for which the low-boiling medium was selected in such a way as to obtain maximal possible power output of the vapour turbine and, consequently, the highest efficiency of the combined cycle. The analysis also included vapour micro power plants with heat regeneration for so-called dry media and cycles without heat regeneration for so-called wet media. The amount of thermal energy available for utilisation in the cogeneration micro power plant at the assumed condenser temperatures equal to 95ºC, 55ºC and 30ºC, respectively, was assessed. The most favourable medium in terms of the obtained power output and efficiency of the combined cycle was selected and the effect of the low-boiling medium on design parameters of the vapour micro turbine was assessed.
