Numerical code describing fuel particle burnout

A numerical code calculating the burnout time of a single secondary fuel particle was developed. Combustion modelling was performed by numerical calculation of energy and mass balances on the particle. Kinetic data for pyrolysis and char combustion stages, as determined by thermogravimetric analysis, were used.

The accrued results and conclusions hold for all secondary fuels studied, while the predictions of the simulation model were in agreement with the results of other researchers’ efforts. The effect of uncertain parameters on model predictions was investigated and it was proved that the particle diameter, moisture content, oxygen concentration and especially the gas temperature have the greater influence on the calculated results.

Combined use of the developed combustion model with thermogravimetric studies provides a comprehensive view of biomass combustion behaviour and this methodology can be incorporated in advanced computational tools for the design and operation of large scale fluidised bed combustion installations.
