Exhaust gas data at specified MCR (ISO)
At specified MCR (M), the running point may be in
equations [4] and [5] considered as a service point
where P
S%
= 100, ∆m
s%
= 0.0 and ∆T
s
= 0.0.
For ISO ambient reference conditions where ∆M
amb%
= 0.0 and ∆T
amb
= 0.0, the corresponding calcula-
tions will be as follows:
M
exh,M
= 216,000 x x (1 + ) x (1 + )
x (1 + ) x = 171,763 kg/h
M
exh,M
= 171,800 kg/h +/-5%
T
exh,M
= 245 - 8.1 - 3.0 + 0 + 0 = 233.9° C
T
exh,M
= 234° C -/+15° C
The air consumption will be:
171,763 x 0.982 kg/h = 168,671 kg/h <=>
168,671/3,600 kg/s = 46.8 kg/s

Final calculation
By means of equations [4] and [5], the final result is
found taking the exhaust gas flow M
L
1
and tempera-
ture T
L

from the ‘List of Capacities’:
M
L

= 216,000 kg/h
M
exh
= 216,000 x x (1 + ) x
(1 + ) x (1 + ) x = 146,716 kg/h
M
exh
= 146,700 kg/h +/- 5%
The exhaust gas temperature
T

= 245° C
T
exh
= 245 - 8.1 - 3.0 - 8.8 - 11.7 = 213.4° C
