Filed:

Dec 31, 2008

Appl. No.:

12/347376

Inventors:

Ravindra Annigeri - Roswell GA, US
Jeffrey S. Goldmeer - Latham NY, US
Anthony B. Campbell - Simpsonville SC, US
Joshua S. Sater - Greenville SC, US

Assignee:

General Electric Company - Schenectady NY

International Classification:

F02C 3/20

US Classification:

60 39463, 60 39281

Abstract:

A flexible and automatic system and method for blending an inexpensive secondary gas with a primary gas fuel for operation of a Dry Low NOx gas turbine. The secondary gas may be a gas fuel such as hydrogen, ethane, butane, propane and liquefied natural gas or an inert gas. Combustion dynamics are avoided by controlling the blended fuel within a permissible range for a Modified Wobbe Index. Combustion dynamics and gas turbine exhaust emissions may also be monitored to maintain safe combustion with the blended fuel. A gas turbine control system may adjust the blend and temperature of the primary gas fuel and the secondary gas to promote desired combustion.

Abstract:

Embodiments of the disclosure provide a method for operating a combined cycle power plant (CCPP). The method may include generating a power plant model for operating the CCPP, determining whether at least two gas turbines in the power plant model generate a power output, and modeling a fuel consumption of the CCPP for a baseline split ratio between the at least two gas turbines. The method may also include determining whether the variant split ratio meets a quality threshold for the CCPP, and adjusting the CCPP to use the variant split ratio in response to the variant split ratio meeting the quality threshold.
