- Abstract
- A laminar flow reactor has been developed which gives a uniform temperature and oxidizing medium in which to study the initial stages of combustion of various condensed phase fuels, in particular, coal/water slurries. In conjunction with the flow reactor, an in situ particle counter has been used to determine the atomization characteristics of various slurry mixtures and to monitor the change in size distribution with increased residence time in the reactor. Initial size distributions and subsequent evolution of these distributions vary markedly among the various fuel preparations, emphasizing the importance of the physical properties of the slurry mixture in determining combustion characteristics. High speed movies of reacting coal/water slurries have also been obtained and show the formation of a devolatilization cloud surrounding the slurry particles, similar to previous results for pulverized coal particle combustion.
