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.
In many cases, replacing a pulverizer's static classifier with a dynamic classifier improves the unit's grinding performance, reducing the level of unburned carbon in the coal in the process.
An improved coal pulverizer classifying system including a classifier cone extension to protect coal flow into the pulverizer from the annular fine-lifting airflow from the pulverizer throat. The classifier cone extension replaces traditional intermittent discharge structure, improving flow through the classifier system and reducing the disruptive effects of the discharge on the annular flow ...
Williams Crusher leads the industry in coal pulverizer manufacturing, offering the industry's most advanced direct fired coal and pet coke crushing system. Whether you're looking for a direct fired pulverizer, low-capacity coal size reduction solutions, or something in-between, you'll find it .
dries coal in the grinding zone and carries pulverized coal particles upward into a classifier. Fine pulverized coal exits the outlet section through multiple discharge coal pipes leading to the burners, while oversized coal particles are rejected and returned to the grinding zone for further grinding.
In coal-fired power plant, pulveriser is the first major component, whose performance dictates the total power plant efficiency. Uniform flow rate and desired size fraction at outlet pipes along with higher classifier efficiency are three important measures which decide the pulverizer performance.
Coal Pulverizer/Classifier Detector - Patent application. Abstract: An improved deflector structure for an updraft classifier mill for coal and ore is described.1 is a cross-section of a pulverizer/classifier suitable for use of the invention
COAL-FIRED POWER plants use gearboxes located on the top of each coal pulverizer to drive the rotating classifier. Rotating classifiers ensure that the coal is of the appropriate size for proper ...
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.
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.

B&W Roll Wheel™ Pulverizer Modifications Improve Performance and Reliability Hi-spin stationary classifier The hi-spin stationary classifier retrofit is for louver sections originally supplied with straight top housing pulverizers. This modification allows the same fineness with less air resistance compared to the original classifier.
The air mixes with and dries coal in the grinding zone and carries pulverized coal particles upward into a classifier. Fine pulverized coal exits the outlet section through multiple discharge coal pipes leading to the burners, while oversized coal particles are rejected and .
Overhauling a Pulverizer for Best Performance Typical Triggers for a Pulverizer Overhaul: • Prescribed maintenance interval (hours, tons throughput, months. • Noise, Coal Rejects excessive, Capacity Short. • Repair damaged or worn parts, grinding elements classifier components, etc.

For nearly 100 years—ever since pulverized coal combustion was adapted for power generation—GE has been a leader in coal mill technology for the power industry. That leadership continues today with the world's largest fleet of installed power milling equipment.
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 ...
Correctly sized coal particles pass through the classifier and exit the mill through the discharge duct. Pulverized coal that has passed through the classifier is pneumatically conveyed to the furnace. Coal Pulverizer Types (Impact, Crush and Attrition) The type of pulverizer .
classifiers, and can be installed in new or retrofit applications. The DSVS 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.
raw coal top size, 7% moisture and produces pulverized coal that is 70% passing 200 mesh fineness (red line). This is pretty standard. Now, take that same pulverizer and provide fuel that is 40 HGI, still ¾" top size and still 7% moisture, but increase the fineness requirement to 80% passing a 200 mesh sieve.
Over the course of the life of a coal-fired plant, changes in unit operation may impact the Fuel Delivery System. The FDS comprises the coal feeder, pulverizer, classifier and coal lines. Such impacts may result from environmental requirements such as the Clean Air Act Amendments of 1990 which affect SO{sub 2} and NO{sub x} emissions.
Pulverizer Maintenance and Repair Inc. specializes in coal pulverizer services. Our supervisors have more than 30 combined years of experience rebuilding B&W MPS and EL mills, CE Mills and Foster Wheeler mills.
