Notes:
1) The sum of constituents is not 1.0 because of other compounds not taken into account (eg. Ash)
2) Factors from ‘heat_generators_1’ https://mail-attachment.googleusercontent.com/attachment/u/0/?ui=2&ik=e879a423c9&view=att&th=1639fd76f5ffdc9e&attid=0.1&disp=inline&realattid=1639fd75160493e6f251&safe=1&zw&saddbat=ANGjdJ-
3) Constituents are taken from from ‘Chapter 3 Fuels and Combustion’ https://mail.google.com/mail/u/0/?tab=wm#search/chapter+3+fuels+and+/1639fc39344def75?projector=1&messagePartId=0.1. They may vary from the values used in the main article.
4) The O2 IS CONSUMED – it is added to either C or H to produce water or carbon dioxide. That is, the oxygen is no longer – it has been combined with other compounds to form new compounds.
5) Likewise 1kg of fuel produces more than 1kg of products because oxygen has been ADDED to the C and H.
