Abstract
In pilot entrained-flow slagging gasifiers, high conversion efficiency and low level of pollutant emissions have been observed, but the mechanism leading to this behavior is not fully understood, limiting the capability to scale up their design. In this paper, after a review of the principal mechanisms and modelling approaches already proposed, a new interpretation of the particle-slag interaction is given and some results of the modelling activities are presented to illustrate the main features that can be envisaged in the particle-slag interaction.File in questo prodotto:
