Abstract:

The biomass CHP technology based on updraft gasification and Stirling engines enables the production of high value electricity and heat in an efficient way in applications below 300­500 kWe electric power output. Thus, a technology gap for the electricity production is filled for carbon neutral small scale CHP plants. The technology is currently entering the market with the first commercial installations in Denmark, Germany and the UK. In this paper, a detailed evaluation on the thermodynamic potential, limits and existing boundary conditions for the optimization of the overall electrical plant efficiency on such a plant is presented. The technology also has the benefit of achieving low emission levels especially with regards to particle emissions. This is an important feature since it is usually difficult to meet low emissions on small scale plants, because the possibilities for implementing primary and secondary measures to keep the emissions on a low level is limited. The paper presents the findings from detailed emission measurements performed.
