摘要： Systems and methods include a fuel cell stack extended around a combustion chamber that is configured to provide output products to the combustion chamber to achieve at least one of late lean injection and a desired combustor gas concentration distribution. The fuel cell stack is positioned at a downstream section of the combustion chamber along an axial direction.

摘要： The present disclosure relates to systems and methods that are useful for controlling one or more aspects of a power production plant. More particularly, the disclosure relates to power production plants and methods of carrying out a power production method utilizing different fuel chemistries. Combustion of the different fuel mixtures can be controlled so that a defined set of combustion characteristics remains substantially constant across a range of different fuel chemistries.

摘要： A hydrogen injection scheme can be employed via use of one or more injectors for injecting hydrogen to help entrain local mass while also generating local turbulence that can enhance mixing with a mixture of air and fuel to facilitate enhanced lean combustion, lower peak flame temperatures of combustion, and reduce nitrous oxide (NOx) emissions from the combustion of fuel. In some embodiments, the hydrogen can be injected to help transport heat released during combustion away from the injector to help avoid injector overheating as well. Different injectors can be utilized to provide a desired hydrogen injection scheme for a particular set of design and operational criteria for a gas turbine system or at least one combustion system that can be utilized in a gas turbine system.
