Natural gas vs propane: part 0

Self-tutoring about common fuels: the tutor makes an initial comparison of natural gas to propane.

Natural gas is chiefly methane, CH4; propane is C3H8.

The combustion equation for methane:

CH4 + 2O2 → CO2 + 2H2O

Propane’s combustion equation, on the other hand, is

C3H8 + 5O2 → 3CO2 + 4H2O

Therefore, methane uses 2/5, or 40% as much oxygen as propane to combust; its heat value is about 40% of propane’s as well (38.7 vs 93.2 MJ/m3).
