Abstract

The presented grate firing system is a patented small scale screw burner, which is designed for high
fuel flexibility. This work focuses on the numerical modelling of the boiler via CFD simulations. The in-house
developed CFD models use an Euler – Lagrange approach to predict the thermal degradation of the fuel particles and
the subsequent gas-phase reactions. The CFD models are validated with experimental data from a representative
measurement campaign where the boiler is operated with softwood pellets and the composition of the flue gas is
measured in the primary and secondary combustion zone as well as the boiler outlet. The simulation results agree
well with the data acquired in the measurement campaigns.
