A small-scale gasification system for solid wastes has been developed and tested. In this innovative system, known as the STAR-MEET system, a fixed-bed pyrolyzer combined with a high temperature steam/air reformer is employed. From the experimental results using wood chips and polyolefin (PO) film as feedstocks, it has been demonstrated that injection of high temperature steam/air mixture into the pyrolysis gas can effectively decomposes tar components. As a result, the pyrolysis gas is reformed into tar-free clean gas contains CO and H_2. Experiments of direct steam injection into the pyrolyzer directly were conducted. For the wood chips, feedstock consumption, CO and CH_4 concentration in the reformed gas increased by direct steam injection into the pyrolyzer. For the feedstock which has low melting point like PO film, it was verified that the fixed-bed type of pyrolyzer was suitable for pyrolyzing. Also it was quite demonstrated that the produced reformed gas for a dual-fueled diesel engine was usable for power generation employing.
