Abstract:
This paper presents a study of the atomization and combustion of coal-water slurry fuel sprayed by a pneumatic nozzle based on the use of wall and cumulative jets and the Coanda effect. The droplet size distribution of coal-water fuel slurry at the nozzle outlet was measured by shadow photography. In the region of fuel ignition, the characteristic droplet size in the flow is 20 $\mu$m and the coal particle size is 100 $\mu$m. The results of experiments on an uncooled firing stand with an uncooled 5 MW furnace showed the possibility of efficient co-combustion of coal-water slurry fuel and pulverized coal using the developed burner.
Keywords:
