6.7 Fuel parameters

The basis for correctly determining the quantities describing the combustion process is the knowledge of fuel

parameters. GA-40 T plusplus analyser has stored parameters for several standard fuels. Table 7 presents

parameters for all the analyser fuels.

Tab. 7: Parameters of fuels stored in the memory of GA-40 T plus analyser.

Table 7. shows the following parameters:

CO2

max

- the maximum concentration of carbon dioxide in the combustion gas, a quantity

specific for a given type of fuel. The parameter determines the amount of carbon

dioxide in the combustion gases if the combustion process is carried out with

excess air factor l equal 1.

A1, B - factors which appear in Siegert's empirical formula

α - the factor used to calculate loss caused by incomplete combustion.

It should be assumed

α = 69 for solid fuels

α = 52 for liquid fuels

α = 32 for gaseous fuels
