too large temperature

Hi everyone,
I'm modelling flow on burner.
This burner have many inlets and outlets on pipes and main inlet for air flow and outlet for this.
I use k-epsilon and energy equation. On inlets (on pipes) I model inlet velocity 0.88 m/s and 1073 K temperature. On outlet is pressure outlet with 101325 Pa. On main inlet is velocity 5,5 m/s and 500 K temperature. On domains (150 pipes and main domain are air on 25 degrees celsius. On post processing I have max temperature around 5000 K.
If i have 1073 K max temperature why on post I have 5000 K?
