Do you mean the furnace cement that the flue collector was bedded in?gwgillplumbingandheating.com

@gerry gill is right. It's old furnace cement. Clean it away and spread new furnace cement around the flue collector when you reassemble.gerry gill said:Do you mean the furnace cement that the flue collector was bedded in?

Shouldn't need that much cement. Did something happen to the flue collector?

The original question was about white powder around the combustion chamber. However there is no picture of a combustion chamber. The picture shows the top of the cast iron heat exchanger with very clean flue passages. There is a white powder that covers the part of the cast iron that was not covered by the flue collector box. The actual combustion chamber on this boiler is at the bottom of the cast iron heat exchanger. It is where the fire from the burner tubes is located. the chamber or area where the Fire happens, hence combustion chamber.
Regarding the powder, if that blue sheet metal cover has never been removed until now, that white powder may have been there since the boiler was installed. Drywall dust from a construction job can find its way everywhere. Unless there was an anthrax scare at the time of the boiler install, I wouldn't worry about it.
If it is anthrax, we may not hear from @Jcfenton87 again. Oh Well!Edward Young Retired
After you make that expensive repair and you still have the same problem, What will you check next?

Thank you all for your input. After taking a second look and considering your observations, I’ve determined it is furnace cement. Albeit poorly applied (IMO). We had an issue with our service provider not performing cleanings as prescribed, so this jumped out as a scare, but concluded as benign. I’ll reseal and reconnect ducting just in time for heating season! 🔥
