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.(c) 2021 Published
