Abstract
While burning solid fuels, like biomass, coal and waste, wall-burning will occur to a certain extent. With the coal-fired liquid-bath combustor as an example, the mechanism of coal deposition, movement and combustion on the molten surface are discussed. In order to overcome the limitation of existing simulation methods for burning characteristics in the liquid-bath combustor, this paper proposes a wall-burning model considering the slag flow condition and gives a total computational frame work. From the comparison of simulation results with several other methods, the difference and properties are analyzed, which can provide a guidance for the simulation of liquid-bath combustor and for the simulation of biomass or waste combustion.
