Investigation of wear pattern in a complex coal pulveriser
· The flow field within the pulveriser is slightly asymmetric mainly due to inclined vanes. The region above the pulveriser vane sections towards the left of the inlet duct clearly indicates high velocity zones which is in accordance with the plant observations. This is expected to increase the wear pattern in the lower sections of the mill. ⋅
