Abstract: The hydrodynamics of a biomass-fired 90 MW stoker boiler with vibrating grate was numerically investigated in order to improve the air distribution and gas mixing and boiler performance, as well as to decrease the fouling of the furnace membrane walls. The numerical calculations were supported by experimental visualization and data from a laboratory model of the boiler. The results indicated that by the optimization of the fuel spreading and distribution of secondary air significant improvement of the boiler performance and reduction of the fouling rate may be achieved.
