Experimental study on the slagging and melting characteristics of ashes generated from coal co-combustion with municipal solid waste (MSW) was carried out in a small-scale pulverized coal furnace. The main elements
particle size distribution and morphology of fly ashes were analyzed. Results show that with rising amount of waste
the ratio of Ca
Fe
Cl
and S in the ash increased
but Mg
K
Al
Na
Ti and Si dropped. The morphology of fly ash was observed by scanning electron microscope
finding that the high ratio of waste enhanced the transfer of particles from spherical to layered structures. The fusion temperature descended little within the range of 2%. A small amount of brown particles were found in fly ashes when the ratio of waste reached to 25%. In conclusion
the co-combustion of MSW has little effect on the characteristics of coal ash. These results provide a theoretical basis for the practical co-combustion of MSW in the pulverized coal fired boilers.
