classifiers in pulverizers

Since 1867, B&W has set the standard for proven high availability, reliability and low maintenance on its boilers, pulverizers and other steam generating and auxiliary equipment. We remain invested in coal and will continue to provide quality products and services to keep the fleet of coal-fired power generators operating reliably, efficiently ...

There are three main classifier types (Figure 1): Static classifiers: These are used for semi-fine grinding but have a very low efficiency and limited operational range. Dynamic classifiers: These incorporate a rotating rotor and, consequently, have a wider operational range. High efficiency classifiers: These combine useful elements both of ...

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 …

The pulverizers are truly the heart of a modern pulverized coal-fueled boiler. ... Classifiers should provide the appropriate capability to achieve fineness and also as a classifier, but also homogenize the fuel distribution from pipe to pipe. This mixing function is equally important as coarse particles return to the pulverizer.

Upgrading a pulverizer's classifier from static to dynamic can improve two key pulverizer performance measures: its throughput and its coal fineness. As their name implies, dynamic classifiers (see box) use static as well as rotating vanes to sort coal particles more precisely by size. … See more

The classifier was modelled in four blade lengths of 110.74 mm (original length used in industry), 212.34 mm, 313.94 mm and 415.54 mm. Moreover, at each modelled blade length, four opening angles of 40°, 50°, 75°, and 90° were set. Hence, 16 classifiers models for the developed classifier geometry were numerically performed …

A deflector disposed immediately above and outboard of a rotating vane wheel in a pulverizer/classifier is protected from wear and abrasion by side-by-side abutting high-hardness wear plates having an alloy content of approximately 15 percent chromium and three percent molybdenum by weight. The abutting edge surfaces of the wear plates are …

Carbon black hammer mills and pulverizers are essential to the refinement process as they decrease grit levels and improve the product's overall performance. Carbon black grit reduction equipment works with industrial classifiers to reduce the amount of grit by pulverizing the material to a very fine level and separating large agglomerates.
