In this study, flow inside of the coal mill classifier of Soma B PP suffering from low boiler efficiency due to high unburned carbon loss was numerically analyzed with respect to its initial flow measurements and isokinetic coal samples at the exit of the classifier as a base case. In the numerical analyses, a Eulerian/Lagrangian approach and a ...
content required the mill system grinding capacity to increase by nearly 50% when firing P RB coal. Therefore, three (3) Atrita 556S mills were proposed to replace the existing Atrita 550S mills for the P RB coal conversion requirement. The fuel characteristics of P RB coal and original mill system design coal are listed as follows. Fuel PRB coal

pulverize the coal by impact and attrition. The pulverized coal is then conveyed by air to centrifugal classifiers. 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.
ATRITA Pulverizer System Upgrade for PRB Coal Conversion. During this effort, the DynaRingTM Classifier modifications to the 558S mills commenced. Atrita Pulverizer Design The Atrita mill is an attrition type, high speed and compact designed pulverizer.
The modern coal mill classifier, however, often has an impeller mounted close to the exit of the mill chamber. The impeller is a cage with a set of blades installed around its outer ring. It introduces a secondary classification by the collision effect in addition to the primary classification by centrifugal force [ [11], [12], [13] ].
There have been very few conversions of UK coal mills from static to dynamic classifiers. But test experience with a dynamic classifier at Powergen's Ratcliffe-on-Soar power station has demonstrated significant fineness gain, especially at the coarse end of the particle size distribution curve, and minimal effect on mill coal throughput and operability, with greatly reduced in vibration levels.
mills for this plant have been upgraded by including additional grinding pegs and clips in the mill to provide 20 TPH flow. The DynaRing™ Classifier was installed in Mill C of this electric provider. During a period of several days, coal fineness samples were collected and analyzed.
