7.2.23 Selecting the Correct Fuel

The 9060Z transmitter can calculate several measurements that are based on the oxygen reading and the temperature of the process gas. These calculations also require some details about the chemical makeup of the fuel. The additional calculations are:

 

Oxygen deficiency

 

The volume of oxygen required to bring the combustion back to

 

 

 

 

stoichiometry

 

Combustibles

 

 

This theoretical scale is equivalent to a combustibles analyzer

 

 

Carbon dioxide

The calculated maximum level of CO2 in the combustion gas

 

(maximum dry)

 

 

 

 

Combustion

 

Requires a stack thermocouple and so is only available in single probe

mode

Select the required fuel in function 50 by using the OPTION keys and then press the ENTER key. The table of values in the next 6 functions will be updated for that fuel.
