ABSTRACT:
A counter-flow system for use in a turbine for selecting various mixtures of fluids for use with the system. The system may be used for a combustor for a gas powered turbine which employs a heat exchanger to combust a fuel without the emission of undesired chemical species. A gas powered turbine requires expanding gases to power the turbine blades. Fuel is combusted to produce the required gases. An oxidizer is introduced into the counter-flow system in a first direction before a first portion of fuel is introduced into the oxidizer. The fuel and oxidizer mixture is then flowed through a second pathway wherein the fuel and oxidizer mixture obtains a selected amount of thermal energy. Moreover, in a second pathway an equivalence ratio of the fuel and oxidizer mixture may be altered from the original fuel and oxidizer mixture.
