pulverizer rejects entrained

Geochemical partitioning from pulverized coal to fly

01/11/2020 The pulverizer rejects, often referred to as “pyrites”, are the hard material rejected from the bottom of the pulverizer. The “pyrites” typically, at least for the power plants studied here, represent less than 1% of the feed to the pulverizer but, as a material enriched in pyrite, among other sulfides, the rejection can divert 10% or more of the hazardous elements that otherwise would

Pulverizer rejects disposal Combustion Engineering, Inc.

When the pulverizer rejects are withdrawn from the pyrites hopper 34, air is entrained in the pulverizer rejects/water slurry and passed under high pressure along with the slurry through the sluice pipeline 36. As mentioned previously, a major problem has arisen in the past as a result of the high pressure air entrained in the slurry being injected into the bottom ash hopper 10 at a point
