Abstract
A port () for axially staging fuel and air into a combustion gas flow pathof a turbine combustor (A). A port enclosure () forms an air path through a combustor wall (). Fuel injectors () in the enclosure provide convergent fuel streams () that oppose each other, thus converting velocity pressure to static pressure. This forms a flow stagnation zone () that acts as a valve on airflow () through the port, in which the air outflow () is inversely proportion to the fuel flow (). The fuel flow rate is controlled () in proportion to engine load. At high loads, more fuel and less air flow through the port, making more air available to the premixing assemblies ().
