Coating Above the Burner tip - What impact it to the combustion process?_ English Version
Coating at the burner tip can sometimes occur during Kiln operation, it can affect the shape of the flame and the combustion process in the Rotary Kiln.
On this occasion we will explain what causes the formation of a coating at the burner tip, and what effect it has on the combustion process in the Rotary Kiln.
The coating above the burner tip is formed due to material falling from the rotating Kiln, and the position of the burner enters the Kiln ring.
If the burner tip coating is not cleaned immediately, it will affect the shape of the burner flame and affect the combustion process in the Rotary Kiln.
The effect on the shape of the burner flame is that the fire tends to go up and touch the coating or refractory brick continuously.
This happens because of the turbulence of the axial airflow in front of the burner tip coating.
If this lasts longer or more than 24 hours, it can damage the coating in the Kiln which is exposed to direct fire. It can be seen on changes in Kiln Shell temperature through the Kiln Shell Scanner.
The effect on the combustion process, the quality of clinker tends to be dusty and freelime often gets out of control.
