A Study on Measurement of Light Tar Content in the Fuel Gas Produced in Small-Scale Gasification and Power Generation Systems for Solid Wastes

Abstract

We have been developing small-scale gasification and power generation systems utilizing solid wastes. These systems employ dual-fueled diesel engines, which do not accept condensable tar content in the produced fuel gas. This paper describes a newly developed measurement method for small amount of light-weight tar (light tar) content in the fuel gas in a short time which is appropriate for usage in commercial plants. Furthermore, by employing this measurement method, the technical feasibility of removal of the light tar content in the fuel gas was showed by utilizing sawdust filter or activated carbon filter in the laboratory scale experiment and in the commercial plant.
