Erosive Properties of Pulverized Coal Fly Ash (Review)

  • POWER PLANTS
  • Published:
Power Technology and Engineering Aims and scope

Fly ash produced from burning pulverized coal mainly consists of solid amorphous aluminosilicate spheres, which, with the exception of small particles, determine its erosive properties. Erosive wear and properties of the particles depend to a large extent on external conditions, and specifically, on fuel preparation and combustion. As far as the experimental data on conventional pulverized coal combustion of hard and brown 3B coals are concerned, the acidic-to-basic component ratio has the best statistical characteristics for predicting the erosion coefficient. There are no available data on the erosive properties of fly ash when implementing combustion measures to reduce nitrous oxides.
