From the article:
The paper describes the performance and operational experience in India on a high efficiency, low tar, woody biomass gasifier developed at Indian Institute of Science, Bangalore. This development is also of interest to Switzerland, which has a substantial potential of biomass energy. The test scheme included measurements on tar and particulates and the effluents along with necessary measurements for the mass and energy balance. The results indicate a low tar level to meet the engine specifications and the effluents issuing out of the system could be treated using simpler techniques, as the levels are low.
