There are many issues that reduce fired heater safety, reliability, or environmental performance. Many of these issues are often related to the firebox. Burner design, burner arrangement inside the firebox, firebox dimensions and shape, fuel composition, ambient effects all play a significant role in the success of a fired heater. When these factors do not come together properly, several issues can appear:
The interaction between burners is the least understood by heater designers. Some knowledge resides with the burner vendor, but they usually enter the new heater design process when the burner arrangement and firebox shape have already been determined. At that time, substantial design changes are no longer possible.
Adverse flue gas patterns and flame shapes can be caused by a multitude of reasons:
We have a strong team that has used CFD in heater design and analysis for over 18 years. They have devoted time and effort investigating the effects of heater design and burner spacing on flue gas recirculation patterns.
XRG Technologies will combine its expertise in combustion and CFD to determine the optimal burner layout and firebox shape for new fired heaters.
