Fuel preparation plant description and performance, June 1982-April 1983

The Fuel Preparation Plant processes raw coal by crushing, drying, cooling and screening and mixes this in a predetermined ratio with a sulfur absorbing agent, commonly dolomite. This mixture is used as fuel for the Pressurized Fluidized Bed Combustor at Grimethorpe, South Yorkshire, UK. The plant also contains two systems for the pneumatic conveying of solids: for transport of the prepared raw coal to an intermediate storage silo and for the transport of blended coal and sorbent from the Fuel Preparation Plant to the Main Facility building. Commissioning of the plant began in the summer of 1979. Subsequent operation of the plant up to December 1981 revealed a number of problem areas. The primary screen and primary crusher for raw coal had often become choked with wet solids; the pneumatic conveying systems had proved unreliable and experienced high pipe line wear rates; also, segregation and bridging of solids in the storage silos were experienced. Plant equipment and layout changes were thus implemented in a shutdown period from December 1981 to June 1982. This report provides a detailed description of the process and equipment as in June 1982. From June 1982 to April 1983 the Plant operated more reliably than prior to this period, although certain modifications were still necessary to maintain operation; these are described. After the plant shutdown in April 1983 new systems for pneumatic conveying and a primary screen to remove damp fines from the raw coal were installed; details are provided.
