Verification Tests of NOx and SO2 Emission Abatement in a Glass Batch Preheater. Final Report, October 1, 1988-April 31, 1989

摘要

The objective of the program was to determine the capture effectiveness of both NOx and SO2 by a fluidized bed of glass batch. Glass batch is the raw material used to produce glass. Tests were conducted first in the laboratory, with flue gases from an oil-fired combustor, followed by field testing with slipstream flue gases from a production glass furnace. Results of both tests showed a very high capture of SO2 (in excess of 90%), but only a minimal reduction in NOx levels (less than 10%). Along with the results of the work, likely reaction mechanisms are discussed.
