Abstract
Fluidised-bed air gasification of three different Danish straw feedstocks and Colombian bituminous coal was studied in the PDU-scale test facilities of VTT. The test programme was divided into two different modes of operation. First, the usability of straw as the only feedstock was investigated by operating the gasifier at relatively low temperature normally used in biomass gasifiers. In this operation mode the main aim was to find out the limits for gasification temperatures, set by the sintering behaviour of the straw. Secondly, the use of straw as an additional feedstock in a fluidised-bed coal gasifier was examined by operating the gasifier at about 1 000 deg C with different ratings of straw and coal feeding. The gasifier was operated at 5 bar pressure and at 80 990 deg C. The product gas was cleaned by ceramic candle filters operated at 465-540 deg C. Concentrations of tars, nitrogen com- pounds, sulphur gases, vapour-phase alkali metals as well as chlorine were determined in different operating conditions. (12 refs.)
