Flue gas temperature or flue gas loss | Bosch steam boiler
When using condensing technology, not only the sensible heat which is directly linked to the temperature but also the condensation heat latent in the water vapour is partially removed from the flue gas. Liquid flue gas condensate is produced which must be removed from the flue gas path, neutralised and introduced into the sewer system.

Flue gas heat recovery | Industrial Efficiency Technology
Heat recovery from flue gas is often the best opportunity for heat recovery in steam systems (CIPEC 2001). Heat from flue gas can be used to preheat boiler feed water in an economizer. While this measure is fairly common in large boilers, there is often still room for more heat recovery. The limiting factor for flue gas heat recovery is that one must ensure that the …
