Fluidized bed combustion (FBC) technology is a means of burning high-sulfur coal and various other feedstocks in an efficient, cost-effective, and environmentally acceptable manner. Unfortunately, the wearing or wastage of metal heat exchanger tubes in bubbling FBCs has been reported in a large number of units in commercial service. Presently, it is not possible to explain why some FBC units, or regions of a specific bed, undergo rapid metal loss and others do not. An eight-member cooperative R D venture was formed in 1985 to investigate metal wastage in FBCs. The objectives of the R D effort are to hydrodynamics and erosion in FBCs, (2) develop guidelines for the design and operation of FBC units with minimum metal wastage rates, and (3) demonstrate the feasibility of a continuous erosion monitor for use in pilot plant and full-scale FBC units. Computational models are being refined and used to predict the rates of metal wastage for specific FBC designs and operating conditions. The design guidelines will emerge from the understanding gained from experimental studies and analytical modeling activities. This paper updates the status of ongoing experimental studies. 8 refs., 10 figs., 3 tabs.
