Hi Ben

Yep it was you I was refering too about the coal to gas conversion. I orginally wanted to post a link to another pdf file that actually gave a good explanation of combustion analysis. A lot of information like many guys here seek falls under copyrighted material and is hard to come buy on forums or even the net in general. I wish I could freely digitize and post a library built over 30 years.

There is another condition known as "cold firing" . The internal flame temperature inside the heat exchanger is not hot enough for complete combustion. In coal or fuel oil this produces a noticable increase in soot. But gas is so clean you don't have the soot as a indicator,only the increased CO.

Also its the stack temperature heat that induces the draft,cold fire a boiler and the draft can be reduced to a point where ventilation of flue gases is a issue in some flues depenging on size and configuration..
