Hello,

I try to simulate coal combustion with fluent. In my setup, inlet air temperature is 80 degree , coal injection temperature 50 degree outlet temperature nearly 600 degree, maximum temperature nearly 1000 degree in system, minimum temperature is 39 degree in system.

I do not understand how the temperature lower than my injection(50) and inlet (80) temperature. How the temperature decrease below the 50 degree?

I am sure that my setup is converged.

Could you help me ?

Best Regards.
