It all depends up on the boiler design and fuel. Usually it varies between 800 degC to 1000 degC.

There are different procedures to calculate boiler temperature profile for different types of boilers. But temperature for an industrial type boiler can be calculated at the following locations:
1. Furnace exit.
2. Downstream of screen tubes.
3. Downstream of superheater.
4. Downstream of boiler bank tubes.
5. Downsteam of economizer. Stack temperature.
