Chimney Condensation

I ahve a 35' semi exposed chmney that is icing at the top. The chimney has been lined with a SS liner. The boiler is a Buderus oil fired. The flue pipe is a 10' horizontal run to  the chimney. I have removed the boiler baffles trying to raise the stack temp. The chimney has a slate topper. Any ideas on stopping the icing?

    Nice ice

    Can you tell if the liner is icing?  As long as it's venting OK, a little ice on the bricks is probably little more than a nuisance, and might be the price of efficiency.  If Bacharach is good and there's no cracked section, a raised flue temp might not be worth the extra fuel.
