Silly question" : what are the exact conditions for determining the PCI / PCS of a fuel or motor fuel?
Combustion in the air? In pure oxygen? Initial temperature? Final temperatures (of combustion products and / or inert if in the air)? Empirical or theoretical method?
The wiki page is rather sober: http://fr.wikipedia.org/wiki/Pouvoir_ca ... C3%A9rieur
Precise conditions for determining the PCI / PCS?

It is perfectly clear for physicist chemists for 150 years and more, the bomb calorimeter, or other, etc.:

we manage to have the complete reaction and we measure the heat in addition, with the T after calibration, all with great care, and if we are serious, we calculate the error bars !!!.

I found that regarding the PCS it was done according to the standard NF M 07-030
Found in this old article (2004 all the same ...) that I just updated: https://www.econologie.com/pouvoirs-calo ... s-534.html
ps edit: written at the same time as dede, this link is more complete than the german version http://en.wikipedia.org/wiki/Heat_of_combustion but where is the french version ????

Do a image search or an text search - Netiquette of forum
Go back to "Fossil energies: oil, gas, coal and nuclear electricity (fission and fusion)"
