Flue gas temperature or flue gas loss | Bosch steam boiler

The flue gas temperatures at the boiler outlet are normally roughly 60K above the temperature of the product inside the steam boiler. At an operating pressure of 10 bar, which corresponds to a saturated steam temperature of 185°C, the flue gas temperature is therefore roughly 245°C. This corresponds to a flue gas loss of roughly 11%.
