Residence Time Behaviour of Solid Material in Grate Systems

摘要

Grate systems are frequently applied in the field of thermal waste treatment. The description of the incineration process by a mathermatical model is a very interesting task for research and developmnet even today. Therefore, the description of the solid material transport and of the mixing behaviour along the grate is an improtant precondition. The transport and the mixing behaviour both depend primarily on the constructive parameters of the grate (e.g forward or reverse acting system). Furthermore, material properties (density, diameter etc) and operation parameters (mass flux, grate velocity etc.) must be taken into account.
