- The FMA Linear Pocket Feeder (LPF) is a positive displacement feed system in which the pressure seal is developed by a set of mechanical labyrinth seals between the piston rings and the sealing tube. The pressure seal is completely independent of the type and size of coal used. The LPF can maintain a pressure difference with no coal in the system and can achieve steady state operation in less than a minute after startup. Coal flow rate can be changed while the LPF is operating at design speed and operating pressure with no effect on the LPF's performance. The LPF has the potential for operating on all types and sizes of coal as long as they are free flowing. The existing LPF will be upgraded utilizing the knowledge gained during the previous 330 hours of operation. The loading station will be redesigned to allow the infeed of coarse coal in such a manner that minimum degradation occurs during entry into the pockets of the feeder and feed of pulverized coal in a way that minimizes entrapment of air under the coal charge to allow quicker settling. Certain other proposed design changes are described also. (LTN)
