Classification performance of model coal mill classifiers

Mar 01, 2020· 1. Introduction. The classification performance of the air classifier in a vertical coal mill determines the size of pulverized coal particles. Thus, the classification performance will influence the ignition, burning, and burnout of the coal particle, and NO x formation in the furnace as well [,,, ].The first generation of the coal mill classifier used static guide vanes to produce a

US5957300A Classifier vane for coal mills Google Patents

An improved vane of the type adapted for use in the classifier cage of a bowl mill type coal pulverizer. The improved vane is designed such that its lower end extends below the classifier cage inlet when the vane is mounted in the inlet. In a preferred form, the vane has a generally trapezoidal shape with a longer lower edge. The vane is additionally bent or curved over a major portion to

INVESTIGATION ON CLASSIFICATION EFFICIENCY FOR COAL

The effect of the settings of the classifier vane angle on the coal classification efficiency was numerically investigated by several researchers 22]. The [2, 20-effect of inlet air velocity, flow vortex and turbulence on the efficiency of a scaled down model of a static-air classifier was investigated by using a two-dimensional CFD model [2].

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. Fineness levels can be adjusted by changing the classifier speed while the mill is on-line.
