Abstract
A deflector ring includes a generally annular body, and a plurality of static straightening vanes arranged interior to the body, the vanes dividing the body into a plurality of substantially equal sections. The vanes are configured to straighten a swirling flow of solid particles as they enter the annular body, and to divide the swirling flow into a plurality of straightened flows that are communicated to a turret positionable above the deflector ring.
Claims20
A deflector ring for a pulverizer, comprising:
- a generally annular body;
- and
- a plurality of static straightening vanes arranged interior to the body, the vanes dividing the body into a plurality of sections;
- wherein the vanes are configured to straighten a swirling flow of solid particles as they enter the annular body, and to divide the swirling flow into a plurality of straightened flows that are communicated to a turret positionable above the deflector ring.
A method for controlling the output of coal in a plurality of coal outlet pipes in a coal pulverizer, the method comprising the steps of:
- modifying, or retrofitting, a portion of a coal pulverizer with a deflector ring, the deflector ring comprising:
- a generally annular body;
- and
- a plurality of static straightening vanes arranged interior to the body, the vanes dividing the body into a plurality of sections.
A classifier for a coal pulverizer, comprising:
- a plurality of classifier vanes arranged in an annular ring;
- and
- a deflector ring concentrically arranged within the annular ring, the deflector ring having a generally annular body and a plurality of static straightening vanes arranged interior to the body, the straightening vanes dividing the body into a plurality of sections;
- wherein the classifier vanes are configured to generate a swirling flow of coal within the classifier;
- and
- wherein the straightening vanes within the annular body are configured to straighten the swirling flow of coal as it enters the annular body, and to divide the swirling flow into a plurality of straightened flows that are communicated to a turret positioned above the classifier.
