What is this goo inside my oil burning HW heater?

Please take a look at the attached photo of the flue on my 10 year old Bock 32e oil fired water heater. In addition to the soot, there seem to be these balls of goo - what are they? Where are they from?

    Bock

    It's looks like incomplete combustion to me. What burner, and nozzle specs are you running, and where is the baffle that goes in it?  I think someone has down fired too much, or low pump pressure, incorrect nozzle and adjustment, or all of the above

    We Just Had It Serviced...

    this past June, but I'm not sure if it was ever serviced beforehand!



    The burner tech did not mention anything out of the ordinary, but he had to poke a hole in the stackpipe for his combustion analyzer, which makes me think it wasn't ever done before.



    Bill: What is this baffle? Do you have a picture or part number that I could call Bock with?

    anode

    Hello:  It looks like the anode has never been replaced.  It's time!



    Yours,  Larry

    baffle

    It looks like a bullet that is hollow , has no point, about 2 inches around, and 6-7 inches long. The only reason it should be pulled is during cleaning, or if there is not a negative draft overfire. It may also be a leaking tank, but let's hope not.
