Inclined Firing System

One of the most common issues faces by operators and owners is high tube metal temperature in fired heaters. Most tube failures in fired heaters occur due to high tube metal temperatures (TMTs). Flame impingement due to long burner flames results in higher TMTs and coking that affect the performance of the heater.  

Furnace Improvements developed the patented Inclined Firing System (IFS) to reduce flame impingement on heater tubes.  With this burner arrangement, a heater will have the following advantages:  

★ Elimination of hot spots
★ Longer tube life
★ Increased heater run lengths
★ More uniform heat transfer along the tubes’ lengths
★ Lower coking rates of internal tube surfaces
