Boiler Questions and Answers regarding Your Boiler

Stack Temperature = 340 degree F. Room Temperature = 80 degree F. Gas analyzer reports CO2 = 10% and CO = 0 Subtract room temp from flue gas temp. 340 – 80 = 260 deg. F. From the Hays Chart, at 260 deg. F. and 10% CO2 you find a stack loss of 15.6% exiting the stack. Add for radiation and convection losses (available from your boiler

Industrial boiler technology for beginners

On the front of the boiler is an external reversing chamber, which again reverses the flue gases and leads them to the end of the boiler in the 3rd smoke tube pass. Hot water boilers are normally completely filled with water during operation. Steam boilers on the other hand are only 3/4 filled with water; the upper quarter is the steam space.

Sep 20, 2017 · Depending on the size of the existing opening, and what is need for the new boiler, and the new lower stack temperature, I would probably recommend a chimney liner. Especially if you're firing a new, properly sized (from a heat loss) boiler. It probably only needs a 5 or 6" liner and your old chimney could be much larger.

Sep 08, 2021 · Getting back to the original question- I'm familiar with the older Smith 8 series boilers (current ones are rebranded Peerless). They're built like tanks. So if that were my house, the first thing I'd try is down-firing the burner slightly. As long as the stack temperature is above 350° F or so, it should run fine without condensing.

Flue Temperature - an overview | ScienceDirect Topics

The improvement in boiler efficiency can be determined by measuring the stack flue gas temperature. The stack gas temperature should decrease when the turbulators are installed. As a rule of thumb, a 2.5% increase in the boiler efficiency is expected for each 50°C (90°F) decrease in the stack flue gas temperature.
