Two different particle sizes (viz. 100 and 500 μm) were simulated using a granular Eulerian–Eulerian approach. Since the total feed to the simplified pulveriser was about 0.8 tons h −1, 0.4 tons h −1 of each of the categories was introduced from the solid inlet. Density of the simulated coal particles was 1800 kg m −3.

Let's take two different original equipment manufacturers' pulverizers sized for about 120,000 pounds of coal pulveriza-tion per hour: one an RP mill design (Figure 1) and …

There are several studies where CFD has been applied to a coal pulveriser [1,[4][5] [6] but none has focussed on the single phase swirl aspect of the flow. Benim et al. [1] simulated the gas-solid ...

Description. Pulverization is currently the favored method of preparing coal for burning. Mechanically pulverizing coal into a fine powder enables it to be burned like a gas, thus …
