Title: Retrofitted pneumatic conveying system upgrades ROM coal handling system
Abstract: This article describes a new pneumatic coal handling system which avoids degrading coal beyond a 5% fines content and controls coal dust in a sensitive fuel storage area. The original pneumatic conveying system for run-of-mine coal no longer met the demands of a nuclear weapons waste material recovery facility in Richland, Wash. Therefore, Kaiser Engineers Hanford Co., which operates the facility for the US Department of Energy, chose to upgrade its pneumatic coal handling system for three rotary grate coal-fired boilers. Installed in October 1993, the newly retrofitted coal yard storage fuel handling system boasts a dust-free capability. It consists of two Denseveyor systems that transfer coal (fuel size 2 inch x 0) from railcar ground hoppers to three service bunkers above the boiler stokers. There also are two dustless outloading towers for yard storage stockpiling.
