The effect of disintegrated iron-ore pellet dust on
The reason is, in calculating the deposition rate values only mass of the collected deposits per time was taken into account and the ash content in Cases 2 and 3 is substantially higher (owing to the presence of pellet dust, with the addition rate of 20 g/h) than that in Case 1 where only coal ash particles are present.
