The Viking gasification plant at the Technical University of Denmark was built to demonstrate a continuouscombined heat and power operation of a two-stage gasifier fueled with wood chips. The nominal input of thegasifier is 75 kW thermal. To validate the continuous operation of the plant, a 9-day measurement campaignwas performed. The campaign verified a stable operation of the plant, and the energy balance resulted in anoverall fuel to gas efficiency of 93% and a wood to electricity efficiency of 25%. Very low tar content in theproducer gas was observed: only 0.1 mg/Nm³ naphthalene could be measured in raw gas. A stable engineoperation on the producer gas was observed, and very low emissions of aldehydes, N₂O, and polycyclic aromatichydrocarbons were measured.
