Flue Gas Temperature Boiler

Combustion Efficiency and Excess Air

15/3/2018 · The 600 MW coal-fired once-through Boilers with opposed firing at a power plant are found to experience marked temperature variation and even overtemperature on the wall of the heating surface as a result of flue-gas temperature (FGT) variation in the boiler. In this study, operational adjustments were made to the pulverizing, combustion, and

What temperature should a condensing boiler be set at? | …

The maximum temperature that we recommend you set your radiator output to is 80 °C. If you have a conventional boiler system, your water cylinder will have its own thermostat. This is usually fitted on the side of the tank. You should set the temperature between 60 and 65 °C but for maximum efficiency, it should be set to around 60 °C.
