Hi,
Contaminants are accumulating on the lens of the flame scanner even with purge air being sourced from the core air fan. The flame scanner is intended to detect the flame quality and pulsating intensity of combustion happening in the burners, through the sighting tube.
There has recently been a lot of dust accumulating on the lens of the flame monitor. While the purge air system we have installed is supposed to blow away the contaminants, it has failed to do so - resulting in manual cleaning.
This accumulation of contaminants has also resulted in boiler flame loss tripping and thus the mill tripping.
Is the problem the insufficient flow rate / pressure of the purged air from the core air fan?
Could using other technologies (say a compressor) be helpful?
How else could this problem be solved since it is very grave.
Thanks
