Defines the O2 content of the combustion air. The LMV52 mus
t see this value +/- 2% during
prepurge. This value can be adjusted if O2 enriched air is used.
For user-defined fuels, this
represents the volumetric fuel / air ratio needed for
stoichiometric combustion of the fuel.
For user defined fuels, this represents the quantity of flue gas generated (wet basis) when
either one cubic meter (for gases) or one kg (for oil) of fuel is combusted at stoichiometric
conditions.
For user defined fuels, this represents the quantity of flue gas generated (dry basis) when
either one cubic meter (for gases) or one kg (for oil) of fuel is combusted at stoichiometric
conditions.
A2 (S)
For user defined fuels, these values are adjustable constants for calculating the combustion
efficiency when firing gas or oil.
