  • CFD based investigations into optimization of coal pulveriser

    A dimensional sketch of a typical pulverizer is presented in Fig. 1 (a).A schematic diagram showing the air and particle streams in a pulverizer are presented in Fig. 1 (b). The raw coal from the coal feed chute (8) mixes with returned oversize material (7) to form a mixed stream that passes between the grinding balls and bottom grinding ring in …

  • Optimum Operation and Maintenance of EL Pulverizers

    mill working on the ball bearing principle. EL pulverizers are manufactured in 18 sizes ranging from EL-17 to EL-76. The numeric specification on ... classification separates coarse and fine coal particles. Homogenization of the stratified mixture leaving the pulverizer can be achieved with intense swirl. More massive coal particles (lower ...

  • Model predictive control for an industrial coal pulveriser

    The coal-pulveriser/coal-mill is an important subsystem upstream of boilers in coal-based thermal power plants. The efficient boiler operations demand optimum combustion-air to coal-fuel ratio (AFR). In fact, portion of (preheated) combustion-air called primary-air, passes through coal-mill and carries pulverised coal to the boiler. The safe, …

  • A Comparison of Three Types of Coal Pulverizers

    The BTM is a low-speed mill that primarily grinds coal by impact and attrition. The VRM is a medium- speed mill that grinds coal by compression and, because of the low coal inventory in the mill and flat grinding surfaces, develops shearing action as well. For both mills a constant centrifugal force is maintained. The speed

  • Multiphase flow simulation of a simplified coal pulveriser

    The mill classifier allows the fine enough particles to pass on to the external burners, while the coarser size particles are returned to the mill rotating table for further grinding and size reduction. ... Coal pulveriser is a device used for separating large and small particles by relying, in general, on centrifugal forces to cause different ...
