Abstract
This paper takes GE’s PG9351FA gas turbine as the research object. From the perspective of energy conservation and mass balance, the compressor, the combustion chamber and the turbine are modeled separately, and then the models are coupled. Key parameters such as fuel, air and gas properties, unit fuel volume, cooling air volume, cooling air volume of the first stage vanes, equivalent turbine front temperature, and compressor efficiency are obtained through the model. The research results meet the engineering error requirements and have certain reference significance for the thermal design of gas turbines.
