Abstract:

The application of CFD simulations is gaining increasing importance for the development of furnaces and boilers. Despite the high complexity of the underlying processes, BIOS has developed a CFD model for biomass grate furnaces and successfully applied it for the development and optimisation of numerous plants of all scales. In this work, selected results from the simulation of continuously operated furnaces, wood log fired stoves and boilers, as well as results from CFD simulations of NOx and fine particle formation are shown in order to demonstrate the advantages and application possibilities of advanced CFD simulations for small­scale biomass combustion plants. The results show, that the CFD­aided technology development leads to reduced emissions, a better utilisation of the furnace volume, an increased fuel flexibility and an enhanced plant efficiency. Furthermore, CFD simulations result in reduced development times, test efforts and an increased security during plant development. Finally, a deepened understanding of the processes in biomass combustion plants is achieved. The applications of CFD models for small­scale plants show, that they are highly efficient tools for the development of new plant series.
