b) Cement kiln (cyclone outlet gas)
Cement production consumes approximately 100 liters or more of fuel (heavy oil) per ton of
cement. Thus, combustion management by means of O
2
analyzers has become a critical ele-

There are cases in which O
2
, CO, and CO
2
measurements are performed using a sampling
system at the kiln outlet.
