Biomass, especially chipped wood, is commonly used as a fuel for district heating in Austria. Between 2005 and 2013 the energetic end use for district heating from solid biomass increased from 10 PJ to 34 PJ. Especially in winter times the water content of the biomass fuel in district heating plants often reaches 50% or even more. Thus, the recovery of condensing heat from water vapour in the flue gases is necessary for reaching high energetic efficiencies. One possible technology is the open sorption process for the heat recovery from the flue gases. The construction of a test facility for an open sorption process and first experimental tests are discussed within this paper.
