3.4 Derivation of the oxygen balance for incomplete combustion

  3.4.1 The oxygen input in g/h is:

(2-7)

  3.4.2 The oxygen output in g/h is:

(2-8)

based on the following definitions and formulae, the individual gas components are calculated in g/h related on wet exhaust gas (GC is the soot in g/h).

(2-9)
(2-10)
(2-11)
(2-12)
(2-13)
(2-14)
(2-15)
(2-16)
(2-17)

  3.4.3 EXHDENS is calculated using formula (2-42) in 3.6 of this section.

(2-18)

where:

 (2-19)

  3.4.4 The first bracket is defined as Factor1, the second one as Factor2 (see also formulae (2-4) and (2-5)).

  3.4.5 The consumed air mass and the exhaust gas mass may be calculated using the following formulae:

(2-20)

and accordingly:

 (2-21)
