Appl. No.:

09/930932

Inventors:

Robert Frank Hoskin - Duluth GA 30096-3084

International Classification:

C23C 836

US Classification:

148222, 148210, 148237, 148279, 427142

Abstract:

This invention pertains to the repair of parts comprising metals, and surfaces and coatings of these parts using reactive metals coating processes. Processes such as chemical vapor deposition (CVD), physical vapor deposition (PVD), plasma spray, and reactive coating (boronizing, carburizing, nitridizing, carbonitridizing, etc. ) are known for producing durable coatings or surfaces on metal parts, and the present invention provides a means to spot-repair these coatings or surfaces without excessive buildup of repair material on undamaged areas.

Filed:

Feb 9, 2010

Appl. No.:

12/702557

Inventors:

Robert Frank Hoskin - Duluth GA, US

Assignee:

General Electric Company - Schenectady NY

International Classification:

F02B 27/04
F01N 3/00

US Classification:

60286, 60273, 60276

Abstract:

Systems and methods are provided for controlling ammonia slip downstream of a selective catalyst reduction (SCR) system. The SCR system can include a SCR reactor having a catalyst, inlet, and outlet. The SCR system can also include an injector for injecting a reductant into the SCR reactor at a location upstream from the inlet of the SCR reactor. An estimated value, a reference value, and an error between the two values of ammonia adsorbed on the catalyst surface can be provided. A saturation indication can also be provided to indicate whether the catalyst surface is saturated with the estimated value of adsorbed ammonia. The saturation indication and the error between the estimated and reference values of adsorbed ammonia can be used to adjust a command signal by an open-loop control scheme. The injection of the reductant into the SCR reactor can also be regulated by the command signal.

US Classification:

700291, 706 25, 706 21

Abstract:

The present disclosure relates to the use of hybrid predictive models to predict one or more of performance, availability, or degradation of a power plant or a component of the power plant. The hybrid predictive model comprises at least two model components, one based on a physics-based modeling approach and one based on an observational or data-based modeling approach. The hybrid predictive model may self-tune or self-correct as operational performance varies over time.

International Classification:

F01K 13/00
F01K 27/00

US Classification:

60645, 60643

Abstract:

A heat recovery steam generator (HRSG) is coupled to a gas turbine engine that is configured to combust a fuel in air to produce shaft power and a flow of exhaust gases including oxides of nitrogen (NO). The HRSG includes at least one duct burner for heating the exhaust gases and at least one NOx reduction element coupled downstream from the at least one duct burner and configured to facilitate reducing an amount of NOx in the exhaust gases that are channeled into the at least one NOx reduction element.
