Flue Gas Analysis is performed by inserting a probe into the flue of the furnace, boiler, etc., between the last heat exchanger and draft diverter or any source of make-up air that could enter the flue that did not pass through the combustion process. This is known as 'in-situ' testing.Get Price
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%.Get Price
Dry Flue Gas Losses. This account for major heat losses amongst all. If the flue gases leaving the boiler is at a high temperature than the temperature for which it is designed, then most of the heat is getting wasted leading to reduced boiler efficiency. Heat Loss Due to Moisture in FuelGet Price
The flue gas temperature is decisive for the combustion efficiency of steam boilers without flue gas condensation. The feed water used in the economiser to cool the flue gases in systems with thermal deaerating is however not colder than 103°C. This can only be used to reduce the flue gas temperature economically in the economiser to roughly 120°C.Get Price
