Where does the following formula for the comprehensive thermal efficiency of the heating furnace come from? How did you push it out? Ask for the source of the formula, the more detailed the better: lol Is the exhaust gas temperature before heat exchange with the air preheater (just out of the furnace top temperature) or after heat exchange?

For calculation of thermal efficiency of petrochemical tubular heating furnaces, see SH/T3045 "Design Calculation of Thermal Efficiency of Petrochemical Tube Furnaces"

The boiler heat balance equation has been changed.

Is there a detailed derivation process? It is best to have a source so that it is easy to find. I also read SH/T3045 "Design Calculation of Thermal Efficiency of Tube Furnaces for Petrochemical Industry", but there is no specific process and it is all principled stuff.
