A Comparison of Three Types of Coal Pulverizers

Properly sized pulverized coal exits the classifier into coal piping for transport to the furnace. Oversized pro- duct is, however, separated and returned to the mill for further grinding. There is minimal metal-to-metal contact of the grinding elements in the BTM resulting in very little wear and low maintenance.

Computational fluid dynamics (CFD) modeling was conducted on the fuel pipes, mill, and classifier as three separate sub-projects. The three sub-projects of this analysis are briefly described below. 1. Fuel Pipe Transport Evaluation Perform CFD modeling of a typical coal pipe arrangement from the pulverizer outlet to the burner


classifier itself – such as separation efficiency or pressure loss – the materials to be classified also play a role. The lamellar classifier developed in 1928 was followed by pressure-shock-resistant classifiers for coal mills, rotary classifiers for very moist materials and louvre classifiers for example for creating fine and coarse products.

CFD simulation of a gravitational air classifier

The air classification of manufactured sand (i.e., fine aggregates from crushed rock with a particle size smaller than about 4 mm) is utilised to separate crushed rock material into a fine particle fraction (filler, 100 mu m). Reducing the filler content of the manufactured sand is especially important for the concrete industry to ensure the rheology of the cement paste. There is an on-going ...

Flow visualisation and velocity measurements in a vertical

The aerodynamics within a reduced scale model of a vertical spindle coal mill static classifier are investigated to provide data for improving classifier particle separation predictions and the validation of computational simulations. Quantitative data for these purposes was obtained by measuring velocities using three-dimensional Laser Doppler Anemometry. Flow visualisation was also used to ...
