Influence of particle size on performance of a pilot-scale fixed-bed gasification system

▸ The effect of particle size on the gasification performance of a gasifier was investigated. ▸ Peach prunings were used at five different size fractions. ▸ As particle size increased, the gas yield increased while the tar and dust content decreased. ▸ More kinds of hydrocarbons were detected when smaller particle size were used. ▸ The gas produced by the smaller particle size showed a better combustion performance than the larger one.
