Urea injection under Non-premixed combustion
 

Hey,

I'm pretty new with Fluent and I'm trying to make simulation of SNCR system in grate fired boiler. The problem is that I can't add urea to the species list so the SNCR tab is not even available. Actually I can't add anything.
There is no problem adding species in Finite-rate/eddy but is it possible to use urea as a reducter in Non-premixed model?

I appreciate any advice or help.
