Abstract
A method for staged combustion in a combustor assembly includes introducing an oxidant stream and a fuel stream at a first location into a combustion chamber to produce a heated stream. A Liquid water stream and an additional oxidant stream, fuel stream or both are then introduced into the heated stream in at least one location along the heated stream downstream from the first location. The additional oxidant stream, fuel stream or both react in the heated stream to generate additional heat that vaporizes liquid water from the liquid water stream to water vapor.

A method for staged combustion in a combustor assembly, the method comprising:
- introducing an oxidant stream and a fuel stream at a first location into a combustion chamber to produce a heated stream;
- and
- introducing a liquid water stream and additional oxidant stream, fuel stream or both into the heated stream in at least one location along the heated stream downstream from the first location, the additional oxidant stream, fuel stream or both reacting in the heated stream to generate additional heat that vaporizes liquid water of the liquid water stream to water vapor.
A method for staged combustion in a combustor assembly, the method comprising:
- introducing an air stream and a methane stream at a first location into a combustion chamber to produce a heated stream;
- introducing a liquid water stream and an additional air stream, methane stream or both into the heated stream in at least one location along the heated stream downstream from the first location, the additional air stream, methane stream or both reacting in the heated stream to generate additional heat that vaporizes liquid water from the liquid water stream to water vapor;
- controlling an amount of the liquid water introduced into the combustion chamber to establish a maximum temperature T1 of the heated stream within the combustion chamber and a discharge temperature T2 of the heated stream from the combustion chamber such that a ratio of T1/T2 is no greater than 1.7;
- and
- introducing the water vapor into a boiler located downstream from the combustion chamber to partially vaporize a second, different liquid water stream.
A combustor assembly comprising:
- a combustion chamber having, in serial flow arrangement, at least a first section and a second section, the first section including a first oxidant feed and a first fuel feed, and the second section including a second feed of oxidant, fuel or both and a first liquid water feed.
