I'm an Instrument engineer and now I'm having a question about the thermal energy of mixture of air and LPG. 

The thermal energy of LPG is 99.6 ~ 105 kBTU/Sft3 but the mixture of air and LPG has the thermal energy is 14,000 ~ 16,000 kCal/m3. 

However, I couldnt find the thermal energy of 1 m3 of air then I couldnt determind the percentage of air and LPG in that mixture. Could you please teach me this point ? 

I'm looking forward to hearing from you.

Thank you very much.

Best Regards,

Dear T. Long, I believe nobody quite understand what are you referring to thermal energy? is it the calorific value or the sensible heat?

Tran Duy Long;

 

I think there is something wrong with your interpretation of the English language.  Like S. Ahmad, I too have never heard of anything such as "thermal energy" after 56 years in chemical engineering.  But, I could be wrong......

 

Can you give our members details on exactly what the process you are describing is all about?  Can you express it in classical thermodynamic terms?

[Pilesar]

The heat of the inlet air is not a critical factor in your calculation. There is more than one correct answer to the heat resulting from your mixture of air and LPG. Depending on the mixture ratio, one spark can make all the difference between little heat and a lot of heat.

Dear Tran,

 

Is it heating value of LPG when this LPG use in furnace?

What is your LPG composition?

 

Thx
