Turbine classifiers for coal pulverizers - IEEE Conference ...
Abstract: Coal pulverizers have utilized a static classifier to generate the desired product fineness which could be effectively burned in a kiln, furnace or boiler. Now there is interest in obtaining a finer product that can enhance the burning efficiency in a coal fired kiln. This is important in light of the increased use of petroleum coke rather than conventional coal.

A Comparison of Three Types of Coal Pulverizers
2018-2-1 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.

2018-7-31 classifier offers increased flexibility to take advantage of a wide (and sometimes lower quality) range of coal. For existing equipment, the DSVS classifier helps in low-NO X burner retrofits by providing higher fineness that reduces unburned carbon. Fineness levels can be adjusted by changing the classifier speed while the mill is on-line.

Dynamic classifiers improve pulverizer performance and ...
2007-7-15 An article in the February 2007 issue of Power explained that one way to improve the combustion and emissions performance of a plant is to optimize the performance of its coal pulverizers. By adding a dynamic classifier to the pulverizers, you can better control coal particle sizing and fineness, and increase pulverizer capacity to boot.
