Hi all,

I recently finished converting a small oil furnace to burn waste oil, specifically used transformer oil removed from X-ray equipment. I've learn a lot about the burner (a standard Beckett AFG bought on Ebay) and the basics of how a furnace operates, but now I want to test the combustion efficiency and learn more about the stack, it's various components, how flue height effects draft, and other things like that. I modifed the burner by installing a pre-heater in-line between the oil pump and the nozzle. The burner and the furnace work great! But I want to test the flue gas and other parameters so that I can tweek its performance and efficiency. Could someone please point me to a good web site that explains basic information about oil burner efficiency and how the design of the stack affects it? Thanks very much!

 

There is some very good information on combustion testing available from Bacharach Inc. in thier "training room".

 

Hi Grady - thanks for the link! I'll check them out.

Any other tutorials or technical information about oil burner furnaces would be much appreciated.
