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 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.
