coal combustion temperature failure
 
Hi everyone,

I m trying to simulate coal combustion in a boiler, and I got this error "temperature limited to 1.000000e+00" at particle injection location. How can I fix this problem?

Also I have to change air properties(viscosity, cp, thermal conductivity etc.). How can I change properties of air?

Even i get that Temperature limited to error i dont think its a problem

Maybe the thermal boundary condition is set at 0 K?

My boundary condition is set to 300K. If I close the injection, there is no failure, but If I open it, temperature limits to 1 K.
