Hi all!! I hope this message finds everyone well.

I want to simulate an industrial furnace. It consists in a rectangular chamber with a burner to supply the fuel and combustion air. The furnace is used to dry clay, which flow through the bottom of the chamber. During the process moisture is removed from the clay. Therefore, the idea is to simulate the combustion chamber but taking into acount the evaporate water from the clay.

I apreciate if you could give me ideas of how to integrate the effect of the water on the combustion process. I have thought to set the bottom wall of the chamber like a mass flow inlet of vapor water. Thanks

There are at least two ways water vapor can affect the rest of the system; it can cool the rest of the gases or it can take part in the combustion. If it is only cooling down, then it is to considered as another species in the multi-species system without involvement in any reaction. If you want to consider reaction, then you have to find out what kind of reaction it goes through and that depends on the rest of the system you have.

PM to be used if and only if you do not want something to be shared publicly. PM is considered to be of the least priority.
