Issues regarding crude tubular heating furnaces
Thread Content
The crude tubular furnace is used to heat crude benzene and steam; should steam flow through the radiation chamber or the convection chamber?
The tubular heater for crude benzene consists of a radiation chamber and a convection chamber; the radiation chamber is located at the bottom while the convection chamber is at the top. In the radiation chamber, gas is used to heat the crude benzene and steam, after which the crude benzene enters the convection chamber for further heating, whereas the steam does not enter the convection chamber.
Thank you, sir, for letting me know and for providing some insight
As long as the design is reasonable and meets the heating requirements, it will work fine.

Vapor is escaping from the radiation room!
Below the tubular furnace is the radiation section, which consists of vertical tubes surrounding the furnace walls; steam and rich oil flow through these tubes respectively. The steam, heated to 350–450 degrees, enters the regenerator. Above that is the convection section, where rich oil flows through horizontal tubes, with no steam present; above this section is the chimney
I agree with what was said above; it’s very comprehensive and detailed
What we have designed is for steam to flow in the convection section.
