| Abstract: | The ash deposition and slagging in an industrial purpose boiler affects the combustion and heat transfer in the furnace and lowers the thermal efficiency of the boiler.With a view to solving the problem of the ash deposition and slagging in the boiler,established was a three-dimensional numerical model for calculating the fly-ash deposition in a chain grate stoker with the fly-ash transmission,collision and cohesion process being taken into account.In combination with the fly-ash precipitation characteristi... |
