Modeling of Side-Fired Furnaces

The total amount of heat that is transferred to the reformer tubes is obtained from the flames and the furnace gas. For this heat transfer, we use the following assumptions. [Pg.490]

The furnace is a well stirred enclosure with a mean temperature different from its exit temperature. [Pg.490]

Radiation is the main mode of heat transfer heat transfer by convection is negligible. [Pg.490]

The flames and the furnace gas are distinct sources of heat. The radiation from these two sources do not interfere with each other. [Pg.490]

There is no net radiative exchange between the enclosing walls (fire-box), and the radiating gas and tubes. Heat is lost from the enclosing wall to the surroundings only. [Pg.490]
