Gas boiler as a heat source for a domestic micro-CHP
Abstract
In the presented analysis a commercially available domestic gas boiler as a heat source for domestic ORC is considered. The applicability of the gas boiler (De Dietrich with thermal power 25 kW) coupled with the laboratory prototype micro ORC setup has experimentally studied. The main aim of the study is to determine the working fluid temperature, attainable heat rates and efficiencies of the whole system. Preliminary investigations show that the boiler was able to provide the saturated/superheated vapour of ethanol and HFE-7100 as a working fluid at required conditions needed in the ORC system and it can be utilized as a heat source in the domestic micro-CHP. Obtained results encourage for further development of micro cogeneration units.References
