ABSTRACT

  The efficiency of separating small dense particles from small light particles in the internal recirculation flow within a CFB riser will be investigated. Currently, there are many systems for separating fine particles. However, these systems lack the efficiency and/or the economics to be commercially viable in many situations. Small particles considered in this study are particles less than 250 micrometers in diameter. This research is directed towards removing pyrite from coal fines at a coal cleaning plant. Also, of concern will be the removal of radioactive particles from the desert sand at the Nevada Test Sites. Progress Report: Quarter I of Year 1 July 1, 2002 Initial activities include the appointment of a graduate student (Jeromy Register) to assist in the design, instrumentation and bringing on-line the experimental system. Space has been obtained in the National Research Center for Coal and Energy's high bay to house the experimental unit. In addition several meetings have been held with our industrial partner, Mr. M. Hamrick, of NORTHCO Co. with respect to building the experimental system. The design of the experimental system has been completed and fabrication of the system has been initiated. A Chemical Hygiene Plan (CHP) is being developed for the operation of the experimental system and should be completed by the end of July, 2002. At this point in the project, there appear to be no major problems to hinder continual progress and achieving the goals of the project.
