How petrochemical Furnaces Work?
The key is Heat Transfer to the crude oil or process fluid flowing through tubes within the furnace.
There are three main heat transfer mechanisms:
1. #Radiation:
Heat radiates directly from the hot furnace walls to the tubes containing the process fluid.
2. #Convection:
Hot combustion gases flow over the tubes, transferring heat to the process fluid by convection.
3. #Conduction:
In some designs, the process fluid tubes might be in direct contact with the furnace walls, allowing for heat transfer by conduction.
