Appl. No.:

11/657501

Inventors:

Donald Keith Morrison - Clinton OH, US
William Theodore Lipinski - Canton OH, US
Donald Keith Hartsock - Wadsworth OH, US

Assignee:

General Electric Company - Schenectady NY

International Classification:

B01D 53/56
B01D 53/74
B01D 53/76

US Classification:

423210, 423235, 4232391, 422168, 422177, 422180

Abstract:

A method for operating a combustion system to facilitate reducing emissions from the system is provided. The method includes supplying an aqueous selective reducing agent from an aqueous selective reducing agent source to an atomizer that is directly coupled in flow communication with the aqueous selective reducing agent source. The method also includes atomizing the selective reducing agent in the atomizer, and injecting atomized droplets of the selective reducing agent from the atomizer directly into a transport stream of flue gas flowing within a temperature zone defined within the combustion system.

Abstract:

An improved gas flow injector has been developed for use in a combustion system. The gas flow injector has an inner nozzle with tubular configuration for directing a first gas stream to a location distal to the gas flow injector. The inner nozzle has an outlet end portion and a longitudinal central axis. Disposed about the inner nozzle is an outer nozzle having a tubular configuration, for directing a second gas stream to a location proximal to the gas flow injector. A diverter is mounted to the outlet end portion of the inner nozzle and extends at least partially into the second gas stream. The diverter has a surface disposed at an acute angle relative to the longitudinal central axis of the inner nozzle to redirect at least a portion of the second gas stream in a direction transverse to the longitudinal central axis. Also disclosed is a method of injecting a gas into a combustion system using the gas flow injector of this invention.
