heal.abstract	The paper presents a numerical simulation of the motion of pulverised lignite particles being transported from the mill exit to the furnace burners in large power plants. Erosion wear caused by the lignite particle impact on the walls of the ducts transporting and distributing the pulverised fuel, is calculated and evaluated. A bifurcation geometry has been selected for the simulation of the fuel distributing ducts. The results demonstrate that the geometry of the fuel distribution ducts determines the velocity distribution and the mass flow rates of the pulverised fuel reaching each furnace burner with direct consequences on the efficiency of the combustion process inside the furnace and indirectly on the emission levels.	en
