| Abstract: | Three types of nozzles: a low-pressure multistage nozzle, an effervescent nozzle and a newly developed internal-mixing air-blast
nozzle, for atomization of Coal-Water Slurry (CWS) were investigated. Influence of CWS properties including surface tension
and apparent viscosity on atomization was studied. Comparisons among the nozzles were carried out in terms of spray droplet
mean diameter and fuel output. Versatility of each nozzle was investigated and atomization mechanism of each nozzle was analyzed
as well. The results showed that the newly developed internal-mixing air-blast nozzle has high fuel output and small mean
droplet size in the spray, but the multistage nozzle has high versatility for handling of low quality CWS. |
