What is the gas temperature at the furnace exit?

The gas temperature at the furnace exit is typically a key indicator of the combustion efficiency and the type of fuel being burned. In many industrial applications, particularly for conventional boilers and furnaces, a gas temperature of around 1100°C is common as it allows for effective heat transfer and efficient operation.

This temperature suggests that the combustion process is sufficiently complete, allowing for high energy recovery before the combustion gases are released into the flue or gas handling system. Higher temperatures can indicate excessive heat loss or inefficiencies, while lower temperatures may imply incomplete combustion or insufficient fuel input.

Understanding the expected range of exit gas temperatures is crucial for optimizing furnace operation, maintaining process integrity, and ensuring emissions remain within regulatory standards. The other options presented do not align as closely with typical furnace exit conditions in practical scenarios, where 1100°C is a standard benchmark for many industrial applications.
