Bottom ash char, which is released and collected from a solid refuse fuel (SRF) gasification pilot plant, has been used as a feed material for one more step of the gasification process. This char contains higher unburned materials than the bottom ash collected from incineration plants. This could have sufficient potential for application to gasification technology. The lab-scale gasification experimental process consists of a downdraft gasifier, a cyclone, a scrubber, and a filtering system for the analysis of syngas. To find the optimal conditions and to decrease loss on ignition, the air equivalent ratio (ER) was adjusted from 0.1 to 0.5. The results of this experiment showed that 0.2 ER was the optimal condition, with 32.41% of cold gas efficiency and 40.41% of carbon conversion ratio. However, compared to the general gasification process, this efficiency and conversion ratio still seem to be low since the feedstock was the leftovers of the gasification process with a lower amount of volatile carbonaceous components. Furthermore, with increasing ER, the loss on ignition of the bottom ash in this experiment decreases due to the enhancement of the oxidation reaction. On average, it decreased by up to about 20% compared to the feedstock.
