             be accommodated by the multistage centrifugal blower used on a fluid bed inciner-
             ator. (Many fluid bed incinerator facilities in England and Europe have waste heat
             boilers that necessitate use of an induced draft fan.) Another disadvantage of the Ven-
             turi scrubber is erosion of throat section and Venturi damper from high-velocity par-
             ticles. Most newer Venturi scrubbers have throat sections lined with silicon carbide
             tiles to mitigate the erosive effect of particulate matter.
