An innovative micro-gasification system for solid wastes is proposed in this paper, whose technical feasibility is demonstrated by using rubber chips as a fuel. In this system, a batch-type fixed-bed pyrolyzer combined with a high temperature steam/air reformer is employed. In the present investigation, it is shown that supply of high temperature air into the pyrolyzer significantly increases the heating value of the pyrolysis gas. With the use of high temperature steam/air mixture as an oxidant for reforming, almost complete reforming of the tar components can be done and they are decomposed into CO, H2 and other hydrocarbon gases with reasonable decrease of the heating value of the reformed gas compared with that of the pyrolysis gas. With packing ceramic balls in the reformer, reforming reactions can be accelerated. The experimental results demonstrate that almost soot and tar free clean reformed gas with the heating value of above 1000kcal/Nm3 can be generated from rubber chips.
