  • Investigations into the blockage of pulverized fuel pipes

     · The blockage of pulverized fuel (PF) conveying pipes on a coal-fired power plant is a hazard accident. An in-depth understanding of the factors that cause PF pipe blockage provides operators with prior knowledge to avoid such accidents. Two representative primary air pipe blockage events are observed on two commercial boilers respectively.
