Spray Dryer/Electron Beam Removal of SO sub 2 and NO/sub X/ from Flue Gas. Technical Progress Report, October 1, 1983-October 1, 1984

摘要

The objective of this project is the pilot scale evaluation of SO sub 2 and NO/sub x/ removal from flue gas by means of a lime slurry spray dryer followed by electron beam treatment. Capital and operating costs of this technique have been determined and shown to be cost effective. The pilot scale work will serve to verify the cost study assumptions and provide design guidelines for commercial applications. The pilot scale system, consisting of a spray dryer, electron beam and fabric filter, treats a flue gas slipstream from a 150 MW coal fired boiler. Parameters such as lime reactant rate and electon beam dosage are varied, and SO sub 2 and NO/sub x/ removal are monitored. It is expected that better that 90% removal of SO sub 2 and NO/sub x/ will be achieved with reasonable operating costs, and early test results verify this expectation. 2 references, 21 figures.
