fired heater design - process flow & heat transfer

FIRED HEATER DESIGN - Process Flow & Heat Transfer

2016-6-15 · FIRED HEATER DESIGN Most fired heaters are counter flow. In parallel flow designs the process fluid inlet would be at the radiant section and the outlet at the top of the convection section. They are typically used in situations where corrosion Specify the Design Heat Flux. Adjust the Design Heat Flux to obtain larger or smaller coil areas.

controlling film temperature in fired heaters

Controlling film temperature in fired heaters

In most applications, it is the oil film temperature, not the bulk oil temperature, that limits the heater duty and the oil life. 1 Film temperature is an important factor in fired heater design for many reasons. Firstly, oil degradation starts in the fluid film, since this is the hottest place for the bulk oil.

While with Indirect Fired Heaters the only variable to be controlled is the intermediate fluid outlet temperature – Fluid Transfer -, always considering not exceeding the film temperature of said intermediate fluid, with Direct Fired Heaters this variable is obviously also very important and critical, but should also share its importance with

fired heaters - an overview | sciencedirect topics

Fired Heaters - an overview | ScienceDirect Topics

Fired heaters may vary in footprint from small radiant helical coil units of perhaps 1.8 m diameter to large crude oil radiant/convection heaters of up to 20 m tube length, and methanol or ammonia reformers of 50 m 2 plan area. Furnaces and fired heaters essentially consist of tubes, burners, a refractory-lined firebox, and a stack. The firebox
