Figure 2. Diagram shows fuel rich area, and coloured arrows show the gas flow through the HPT stages in the engine (Source: General Electric)

Diagram provided by General Electric showing the fuel-rich area in the engine and illustrating the gas flow through the high-pressure turbine stages in the engine.

The diagram indicates that temperatures are higher at the high-pressure turbine stage 1 (fuel-rich zone), and that temperatures decrease as the gas flows aft and energy is extracted by the different turbine stages.
