CO(n) = CO x (20.9 - O2r)
(20.9 - O2m)
D. CALCULATION OF FUEL DATA
For any fuel not specified by Kane International the net calorific value, gross calorific value and composi-
tion should be obtained from the fuel supplier.
The following fuel data has been calculated with reference to the efficiency calculation.
Example 1:
Chemical composition:
C
25%
H2
3%
H2O
50%
Qnet
8.35 MJ/kg
Qg
9.3 MJ/kg *
Max CO2 20.4%
K1n
= (255 x % carbon in fuel) / Qnet (kJ/Kg)
= (255 x 25) / 8350 =
0.763
K1g
= (255 x % carbon in fuel) / Qg (kJ/Kg)
= (255 x 25) / 9300 =
0.685
K2
= Max % CO2 =
20.40
K3
= Wet Loss = [(9 x %H2 + %H2O) / 9300] x 2425
= [(9 x 3 + 50) / 9300] x 2425
= (77 / 9300) x 2425 =
20.08
K4
=
65
(an approximation for wood) *
The fuel values to program into the Analyzer are as follows:
NATURAL GAS
K1g
: 0.763
K1n
: 0.685
K_2
: 20.4
K_3
: 20.08
K_4
: 65
O2r
: 8.0
* Assumed values in the absence of supplied data. See previous appendix for other fuels.
