Stack temperature question Heating Help: The Wall

I now have an entirely straight flue with a stainless steel/titanium liner. Just finished that 3 days ago and I got a heating pro to fire the boiler and do combustion analysis this morning. I have an oil fired peerless boiler. Prior to the chimney work I had a 450 degree stack temperature. The stack temperature is much higher now at 530 degrees.

PRODUCTS OF COMBUSTION OF GASEOUS FUELS AND CALCULATED FLAME

Find the adiabatic flame temperature for a stoichiometric methane/air flame if the initial temperature of the fuel and air is 5, 10, 15 and 20 oC. Take the net calorific value of methane as CV = 50.14·106 [J/kg] The first step is to evaluate, for 1/16 kmol methane (1 kg), the mass of each of the reactants and products.

heat transfer. The stack temperature of a 4-pass boiler will be lower than the stack temperature of a 2 or 3-pass boiler, of the same basic design, operating under similar conditions. Because of this fact, the 4-pass will have higher efficiency and lower fuel cost. This is not an opinion; it is basic heat exchanger physics. The 4-pass design

Adiabatic flame temperature - Wikipedia

The constant volume adiabatic flame temperature is the temperature that results from a complete combustion process that occurs without any work, heat transfer or changes in kinetic or potential energy. Its temperature is higher than the constant pressure process because no energy is utilized to change the volume of the system (i.e., generate work).
