Convection zone and radiation zone on the tubular furnace
Thread Content
May I ask, on a tubular furnace, which part is called the convection zone and which part is called the radiation zone?
The area where the fire burns is called the radiation zone, while the zone where heat is exchanged with the flue gas is the convection zone
The upper part is called the convection zone, while the lower part near the burner is called the radiation zone
The location of the furnace chamber is called the radiation chamber, and the area above it where heat exchange occurs with the flue gases is called the convection section
Understood based on the definitions of radiation and convection
The second floor is correct; the convection zone also has a horizontal component
The flame is like the sun; the areas illuminated by it are the radiant tubes, while those not illuminated are heated by the temperature of the smoke, making them convective tubes
The combustion chamber is the radiation section, while flue gas heat recovery belongs to the convection section. The heat transfer methods are different
