Problems solved by technology

Capturing CO2 from the exhaust gas of a gas turbine combined cycle power plant is very expensive because of: (a) the low concentration of CO2 in the exhaust stack, (b) the large volume of gas that needs to be processed, (c) The low pressure of the exhaust stream, and the huge amount of oxygen present in the exhaust stream
All of these factors contribute to the high cost of carbon dioxide capture from combined cycle power plants

Abstract

Systems, methods, and apparatus are provided for controlling the oxidant feed in low emission turbine systems to maintain stoichiometric or substantially stoichiometric combustion conditions. In one or more embodiments, such control is achieved through methods or systems that ensure delivery of a consistent mass flow rate of oxidant to the combustion chamber.
