Pulverized coal fired boiler
Hello ,

I am simulated 200 MWe tangentially coal fired boiler.

the models are :RNG -k-e, P-1, Species transport with volumetric reactions , diffusion controlled, constant rate devolatilization.

The problem is temp shoots up to 3000K. I have checked heat balance it is 6% off. The adiabatic flame temperature is 2500K. The actual operating temp is < 1800K.

Pl advice
