5 Factors Killing Your Industrial Boiler Efficiency & What ...

Dec 02 2016 · "Stack temperature" or flue gas temperature measures the temperature of the combustion gases when they leave the boiler. If the flue gas temperature is high it suggests the heat created by the boiler isn't being effectively used to generate steam. In other words a high flue gas temperature suggests heat is being lost. When looking to address heat loss through high flue gas temperatures it commonly

Flue Temperature - an overview | ScienceDirect Topics

A flue gas analysis of a gas-fired boiler indicates that the CO 2 content is 8% with a gas flue temperature of 204°C (400°F). Determine the overall thermal efficiency of the boiler. Solution. By reading the monograph of Fig. 8.12 the combustion occurs with an excess air of 48% and excess O 2 of 7%. The overall boiler thermal efficiency is about 81%.

Flue gas temperature or flue gas loss | Bosch steam boiler ...

Economiser. 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%.

Flue Gas Exhaust Thermometer - Controlled Combustion

A flue gas exhaust thermometer should be installed near the base of the breeching near the boiler to monitor the outgoing temperature of flue gasses. High flue gas temperature is typically an indication of soot build-up in the fireside of the boiler that causes reduced boiler efficiency corrosion failure of steel reduced heat transfer rates ...
