A Kalman filter based on measurements of combustion air flow led into the furnace and oxygen concentration in the flue gas is designed to estimate the actual coal flow injected into the furnace. With this estimate, it becomes possible to close an inner loop around the coal mill itself, thus giving a better disturbance rejection capability.

In theory, by keeping the O 2 level low (normally below 12%), the possibility of an explosion can be excluded. Theoretically, it is not a problem to control the O 2 content of an air flow. In practical operation of a cement coal mill system, O 2 control is prone to difficulties varying from human error to mechanical failures of different kinds.
