The report, on the status of dry SO/sub 2/ control for utility and industrial boilers in the U.S., reviews curent and recently completed research, development, and commercial activities. Dry SO/sub 2/ control systems covered include: (1) spray dryers with a fabric filter or an electrostatic precipitator (ESP), (2) dry injection of alkaline material into flue gas accompanied by collection of product solids and fly ash in a fabric filter or an ESP, and (3) electron-beam (E-beam) irradiation. Spray drying and dry injection systems generally include a fabric filter or an ESP and control SO/sub 2/ and particulate matter simultaneously; E-beam technology is designed to also control NOx. Spray drying continues to be the only technology commercially applied to utility and industrial boilers. The two new utility systems sold since the last status report (Fall 1982) bring the total utility spray drying flue gas desulfurization (FGD) capacity to about 7200 MWe. Also, 10 recently sold new industrial units bring the total of commercial industrial boiler unit sales to 21. Performance data for five utility systems and three industrial systems were recently published. Some full-scale systems that have come on-line since the last survey have experienced atomization problems and solids buildup on the dryer walls during initial operation. The first trona dry injection application has been announced for a 500 MWe unit.
