- Heat flows from hottest to coolest and, therefore, to produce 1,000F to 1,100F superheated steam and reheated steam outlets, the furnace exit gas temperature (FEGT) must be above about 1,500F at the reheater gas inlet to drive the heat flow into the reheater and superheater to create the desired steam temperatures.

Furnace Exit Gas Temperature (FEGT), The Forgotten Variable. One of the key variables when designing a boiler is furnace exit gas temperature (FEGT). This is usually defined as the temperature in a vertical plane just in front of the convection pass as the flue gas escapes the radiant zone.
Heat flows from hottest to coolest and, therefore, to produce 1,000F to 1,100F superheated steam and reheated steam outlets, the furnace exit gas temperature (FEGT) must be above about 1,500F at the reheater gas inlet to drive the heat flow into the reheater and superheater to create the desired steam temperatures.
Furnace exit gas temperature (FEGT) is one important design/operating parameter to monitor the boiler combustion. By installing Infra-view FEGT Sensor, user can benefit from. Protect the boiler tube & refractory from damage. Excessive high FEGT can damage refractory and increase the rate boiler tube corrosion, and eventually lead boiler tube leakage.

MEASUREMENT OF FURNACE EXIT-GAS TEMPERATURE (FEGT) The Opportunity Monitoring the performance of a power boiler can be a challenging task. One of the primary parameters for monitoring the performance of a power boiler is the furnace exit-gas temperature (FEGT). This measurement provides a direct indication of the heat
or putting it in words: the furnace exit gas temperature is equal to the furnace inlet gas temperature plus the boiler air flow times the air specific heat capacity times the difference between the boiler air outlet temperature and the boiler air inlet temperature divided by the furnace gas flow times the gas specific heat capacity.
