Abstract

A comprehensive computational model for biomass combustion is presented, featuring a solid phase combustion model, a fluid dynamic model for the gas phase, and a solid particle transport and deposit formation model. It is implemented on a Finite Element code, and a test case is considered of a furnace burning wood particles. Results underline the capability of the code to predict combustion conditions and the growth rates of deposits of different particle size over the furnace walls, as well as the most critical locations for particle deposition.
