coal combustion initialization problem
 

I have completed first phase in which I have solved simulation after giving primary and secondary air boundary conditions with their respective temp. In second phase I have given coal boundary conditions and set 1000k as an ignition temp. After 1000 iterations I checked my simulation result but it is showing no temp rise (no combustion). Please guide me for initialization of combustion in CFX

Hi,

I would check the particle trajectories and the also the level of combustible gas in the domain (you can do this by looking at the 'Fuel Gas' mass fraction). If there isn't any, then you need to check your multiphase reactions carefully.
