Effect of the Fineness of Pulverized Coal on th

On the understanding that the characteristics of the gas flow have a major contribution to slagging, a change in the fineness of pulverized coal necessitates taking into account the change in the properties of fly ash, which can either improve or worsen the slagging situation.
