Abstract
In this paper the applicability of the commercial gas boiler (De Dietrich DTG X23N) coupled with the laboratory prototype micro ORC setup was experimentally studied. The main objective was to determine the working fluid capability to obtain required temperatures of vapour prior to the turbine, attainable heat rates and efficiencies of the whole system. The boiler thermal power was 25 kW. Tests were carried out with a single stage turbine specifically designed and manufactured for the facility. Investigations show that the boiler was able to provide the saturated/superheated steam of ethanol as a working fluid at proper conditions needed in the ORC system and it can be utilized as a heat source in the domestic micro-CHP. The attained turbine power reached 1.5kW. In authors opinion it is very important conclusion for the research development on the domestic micro ORC.
