Classifier In A Coal Pulverizer

Dynamic classifiers improve pulverizer performance and more

A dynamic classifier is retrofitted to a vertical-shaft pulverizer by installing a duplicate upper pulverizer casing that houses the classifier’s fixed and rotating vanes, motor, and drive connections. A typical dynamic classifier assembly has a center coal feed pipe and several coal outlet pipes (Figure 6).

Pulverizer - Wikipedia

With adequate mill grinding capacity, a vertical mill equipped with a static classifier is capable of producing a coal fineness up to 99.5% or higher <50 mesh and 80% or higher <200 mesh, while one equipped with a dynamic classifier produces coal fineness levels of …


The DSVS® rotating classifier provides the flexibility to take advantage of a wide range of coal grades and realize potential fuel cost reductions. Retaining the features of our standard fixed loading system, B&W’s Auto-Spring™ pulverizer loading system controls roll wheel loading on-line to provide extended turndown capability.

The Storm Approach to Coal Pulverizer Optimization

The design “capacity” of the same pulverizer will grind 135,000 pounds per hour with fuel that is 55 HGI (Hardgrove Grindability Index) coal, ¾” raw coal top size, 7% moisture and produces pulverized coal that is 70% passing 200 mesh fineness (red line). This is pretty standard.

Pulverizer Fineness and Capacity Enhancements at Danskammer

The mill with the SLS dynamic classifier was able to achieve a 15% increase in capacity over the mill with the static classifier, while maintaining better fineness. The coal particles on 50 mesh were reduced by over 60% and on 100 mesh, by over 50%.

Dynamic classifiers improve pulverizer performance and ...

By adding a dynamic classifier to the pulverizers, you can better control coal particle sizing and fineness, and increase pulverizer capacity to boot. A dynamic classifier has an inner rotating cage and outer stationary vanes which, acting in concert, provide centrifugal or impinging classification.

Coal Pulverizer Maintenance Improves Boiler Combustion

12/01/2015 | Richard F. (Dick) Storm, PE. Optimized coal pulverizer performance is a prerequisite for ensuring the best furnace combustion efficacy. Here are some solutions for overcoming commonly identified combustion problems. Coal pulverizers are the heart of a pulverized coal-fueled boiler.

Coal mill pulverizer in thermal power plants

Nov 17, 2012 · 2.Coal pulverizer/mill system One of the critical power plant components that is relied upon to convert the energy stored in coal into electricity is the coal pulverizer or mill. The coal flow is controlled by the feeder, allowing coal to flow into the pulverizer mill. The pulverized coal and air mixture is then transport to the boiler burner panels.
