Title:
APPARATUS AND METHOD FOR COMBUSTOR
Document Type and Number:
Japanese Patent JP2011202944
Kind Code:
A
Abstract:

To provide a combustor for a gas turbine with multiple nozzles that can operate in various turndown systems to reduce fuel consumption.

The combustor 14 includes an end cover 22, a combustion chamber downstream of the end cover 22, and nozzles disposed radially in the end cover 22. A fixed shroud 36 surrounds at least one of the nozzles and extends downstream into the combustion chamber. The shroud includes an inner wall surface and an outer wall surface. The method for operating the combustor 14 includes a step for running compressed working fluid through nozzles 32, 34 into the combustion chamber, a step for running fuel through each nozzle in a first subset of the nozzles into the combustion chamber, and a step for igniting the fuel from each nozzle 32 in the first subset of nozzles 32, 34 in the combustion chamber.
