Research related to the combustion of coal-water fuel (CWF) is being conducted throughout the world in government, industrial and university facilities. In this paper studies are reviewed of several of many aspects of the combustion process, with emphasis on: atomization and carbon burnout and the properties of CWF that influence these, mainly rheology and particle size distribution; combustion assist measures; ignition; emissions; and single droplet studies and combustion modeling. One combustion research problem receiving major attention is the relationship between the atomization process and CWF viscosity. A qualitative discussion of this subject is presented, as well as that of the droplet formation mechanism of CWF fuels. Lastly, single droplet burning and combustion modeling have been helpful in providing understanding of the combustion processes of vaporization, agglomeration, devolatilization and char formation and burnout. |
