Popis: | Transformation of the fine aerosol of coal-water slurry during the propagation in air was investigated experimentally. It was shown that most probable size of aerosol particles changes from 120 μ m to 270 - 280 μ m during the free space flight for 0.4 m together with deceleration from 800 mm/s to 550 mm/s. The low temperature ignition of such aerosol on the discussed propagation way was analysed using the simulation. It was shown that particles with sizes 50 - 200 μ m ignite inside the observed range of distances from the nozzle. The particles bigger than 50 μ m allows high enough heat production within the 1–1.5 m of the flight and, thus, the observed fine aerosol is fully appropriate for industrial purposes. |
