Appendix–A
Oxygen required (OR) for burning one Kg of fuel
= C X (32/12) + H X (16/2) + S X (32/32) - O2
Stoichiometric air for burning one Kg of fuel = OR/0.233
Where C, H, S, and O2 are species mass per kg of fuel.
Appendix-B
Calculation of equilibrium constant for the reaction
N2 + O2 --> 2 NO
DG0 = -RT ln K0
Where DG0 is the standard free energy of formation. K0 is the equilibrium constant at temperature T.
The most reliable and easily accessible values are those tabulated for
T = 25° C = 298 K. DG0 = 20.69 Kcal/mol for NO formation at this temperature.
K0 = exp (-DG0 /RT)
van' t Hoff equation:
d(ln K)/dT = DH0 / RT2
where DH0 - DG0 = DS0
ln (K1 / K0 ) = DH0 / R x (1/T0 - 1/T1)
K1 = K0 x exp(DH0 / R x [1/T0 - 1/T1]
DH0 = 21.57 Kcal/mol for NO formation. This gives K0 = exp(-34.89) and K1 = 0.000526 for 1200 K.
