摘要: Abstract Defluidisation and agglomeration during fluidised bed gasification of biomass is analysed discussed. It argued that the defluidisation processes, in principle, closely resemble those determine behaviour glass processing. Crucial properties for working with melts are viscosity, stickiness, surface tension, etc. is, however, (very) difficult to theoretically quantify these through thermodynamics or other theoretical means. Hence it will be problematic predict defluidisation. Models predicting must therefore probably an empirical nature. As a consequence this, number tests were empirically respect In total 145 evaluated; 51 defluidised exhibited some kind disturbance. A fuels materials included analysis using multivariate statistical approach. Based on regression equation temperature suggested.
