Trends And Opportunities of Micro-CHP Technologies based on Biomass Combustion

I. Obernberger
Within recent years the interest for micro-CHP applications (nominal electric capacity <100 kWel) based on biomass combustion increased considerably. Typical fields of application for such micro-CHP plants are residential heating, small district heating systems as well as small companies with process heat or cooling demand. In this paper, the following micro-CHP technologies have been investigated regarding technological aspects, status of development and economic constraints: the thermoelectric generator, the Stirling engine process and the micro gas...
