EU-DEMONSTRATION PROJECT BIOCOCOMB FOR BIOMASS GASIFICATION AND CO-COMBUSTION OF THE PRODUCTGAS IN A COAL-FIRED POWER PLANT IN AUSTRIA

Since the early ʹ80 s Draukraft, a local energy supplier within the Verbund group, Austriaʹs largest power supplier, carried out studies and research projects on biomass resource potentials and conversion technologies for electricity production from biomass. The lecture describes different technologies for co-firing in general as well as a new method in detail: "Gasification in a separate, external CFB-reactor and co-firing of the gas in the coal boiler". This was realised in the BIOCOCOMB project by an international consortium consisting of Draukraft/ Verbund (A), Austrian Energy (A), Electrabel (B), EVS (D), ENEL (I) and ESB (Irl), supported by the EU-THERMIE programme. The design basis of the CFB-gasifier for the BIOCOCOMB project in Zeltweg Power Plant was the CFB-technology of Austrian Energy, Austriaʹs largest supplier of systems for thermal energy generation and environmental technology.
