S. Kern, M. Halwachs, T. Pröll, G. Kampichler & H. Hofbauer
A pyrolysis process can be used to split up the biomass in a volatile fraction poor in undesired substances (Cl, N, S, Na and K) and a char fraction where these substances are concentrated. In this way cheap biomass can be used for co­firing in existing fossil fuel power stations without the danger of corrosion, deposition, and emission problems. The aim of the project is the development and demonstration of a biomass pretreatment process based...
