Abstract
A turret includes a generally frusto-conical shaped 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 body, and to divide the swirling flow into a plurality of straightened flows that are communicated to a plurality of coal outlet pipes.
Claims20
A turret for a pulverizer, comprising:
- a generally frusto-conical shaped 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 body, and to divide the swirling flow into a plurality of straightened flows that are communicated to a plurality of coal outlet pipes.
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 turret, the turret comprising:
- a generally frusto-conical shaped body;
- and
- a plurality of static straightening vanes arranged interior to the body, the vanes dividing the body into a plurality of sections.
A coal pulverizer, comprising:
- a grinding mechanism configured to transform raw coal into pulverized coal;
- a classifier configured to receive the pulverized coal from the grinding platform and to generate a swirling flow of coal, the classifier being further configured to reject coarse particles of the pulverized coal from the swirling flow;
- a turret arranged generally above the classifier, the turret having a generally frusto-conical body and a plurality of static straightening vanes arranged interior to the body, the straightening vanes dividing the body into a plurality of sections;
- and
- a plurality of coal outlet pipes in fluid communication with the interior of the turret;
- wherein the straightening vanes within the turret are configured to straighten the swirling flow of coal as it enters the turret, and to divide the swirling flow into a plurality of straightened flows that are communicated to the coal outlet pipes.
