Hello I am trying to design an air heater for a volunteering project. 

I have a specific flow rate of biogas at certain composition (thus I know the heating value), however I don´t know how to calculate the resulting temperature of the flue gases at the beginning of the heater.

 

Can you please advise?

 

Regards

Kangari:

 

You state that you are trying to calculate the temperature of "the flue gases at the beginning of the heater".   I have to guess that you mean that you intend to burn the biogas you mention.  (You never state that!)   And yet you title your thread "Temperature of the Air Evolved".  What are you talking (or writing) about?  Do you mean flue gas resultant temperature or some "air" temperature?   Nobody is going to understand what you are writing about .......

 

I have to guess that you are proposing the combustion of a biogas and want to calculate the resultant combustion gas products' temperature.   Is THAT what you intend to write????   I have changed the title of this thread until advised otherwise by you..........

Hello,

 

Yes that was a confused question by me. Let me rephrase it clearly.

 

I have a forced air heat exchanger and I would like to heat the air using the fluegas produced by burning biogas.

 

During combustion of biogas, I know that the flame has a temperature. However how can I work out the initial temperature of the flue gases. This will help me out to do my energy balance
