Comparison measurements of tar content in gasification systems between an online method and the tar protocol

Such an automatic system was developed at IFK in the past with the goal of commercialization and moreover better comparability of the results from tar measuring. To show its accuracy and advantages over standard methods, comparative measurements with the standard method DIN CEN/TS 15439 at an electrically heated lab scale gasifier at different settings have been performed at IFK over several hours. Then, the results of both measurement techniques were compared to each other. The results show a stable operation of the gasifier and therefore also the tar production and its fast detection with the online system. Furthermore, the comparison of the results from both measurement techniques shows good agreement. A satisfying validation of the online method could be conducted.
