The cogeneration system based on solid biomass using stirling engine

This paper presents a study constructed by a team from Technical University of Cluj-Napoca, with the aim of developing a Combined Heat and Power (CHP) generating unit in the location of the Didactical and Touristical Base Marisel, where there is under construction a building with didactical and accommodation spaces. The builing has 30 rooms and 4 apartments, conference rooms for 120 persons and restaurant room for 100 persons. The designed heating system has been projected with of two heating units of 291 kW
_th
each based on GPL burner. Within this study we propose a cogeneration heating system compound from four units based on the gasification wood biomass and a Stirling engine of 35 kW
_el
and 140kW
_th
each. This solution is recommended by the fact that the Didactical and Touristic Base Marisel is located in a mountain region with many forest all around. The electrical power generated by the cogeneration system 4×35 kW=140 kW
_el
will be used to cover the base power of the load curve and some 450 kW
_th
total absorbed thermal power to ensure the required heating of the building, calculated in the design stage.
