Load ratio of the air preheater in a tubular heating furnace
Thread Content
What is this ratio usually, is there a standard?
Or if anyone knows where to find information on this topic, thank you all
Different heating furnaces have different ratios. For example: if the temperature of the flue gas exiting the convection chamber is 500 degrees, it is cooled down to 180 degrees ； 2 If the temperature of the flue gas exiting the convection chamber is 300 degrees, it is reduced to 180 degrees. These two situations are definitely different. For the heating furnaces in conventional refining units, when the feed temperature is neither particularly high nor particularly low, the load on the preheater is generally around 10% of the load on the heating furnace.
