SUCCESS STORIES
SUCCESSFUL BURNER APPLICATIONS:
FREE-JET Application No: 1
This particular natural draft application was a Stabilizer Reboiler Vertical Cylindrical Heater (35 feet tall, 10.67 meters) with a four-burner configuration. In this application, the customer wanted ultra Low NOx numbers. The heat density in the furnace was over 302,000 Btu/Hr-ft2, with the total heater duty of 35.2 MMBtu/hr. Once the heater was lined out in accordance with the operating parameters, the NOx was measured at 0.0171 lbs/MMBtu (12.2 ppm) by a third party with only trace amounts of CO (less than 1.0 ppm).
FREE-JET Application No: 2
This particular natural draft application was a vertical cylindrical FCCU Charge Heater (43 feet
tall, 13.1 meters) with an eight-burner configuration. In this application, the customer wanted ultra Low
NOx numbers. The heat density in the furnace was over 302,400 Btu/Hr-ft2 with the total heater
duty of 57.6 MMBtu/hr. Once the heater was lined out in accordance with the operating
parameters, the NOx was measured at 0.0148 lbs/MMBtu (10.6 ppm) by a third party with only trace
amounts of CO (less than 1.0 ppm).
FREE-JET Application No: 3
This particular natural draft application was a vertical cylindrical HCU Charge Heater (38 feet
tall, 11.6 meters) with a seven-burner configuration. This unique application had six burners in a circle
with one burner located in the center. The burners were on a very tight burner circle for this
retrofit application. The customer wanted ultra Low NOx numbers for this heater. The heat
density in the furnace was over 177,194 Btu/Hr-ft2 with the total heater duty of 77 MMBtu/hr.
Once the heater was lined out in accordance with the operating parameters, the NOx was measured
at 0.0224 lbs/MMBtu (14.9 ppm) by a third party with only trace amounts of CO (less than 1.0
ppm).
FREE-JET Application No: 4
This particular forced draft application had 525°F (274°C) air preheat and was a vertical cylindrical GDU Charge Heater (61 feet tall, 18.6 meters) with a twelve burner configuration. In this application, the customer wanted ultra Low NOx numbers. The heat density in the furnace was over 277,240 Btu/Hr-ft2 with the total heater duty of 156 MMBtu/hr. Once the heater was lined out in accordance with the operating parameters, the NOx was measured at 0.0149 lbs/MMBtu (10.7 ppm) by a third party with only trace amounts of CO (less than 1.0 ppm).
FREE-JET Application No: 5
This particular forced draft application had 600°F (316°C) air preheat and was a box style Coker Heater
in a Cruciformer configuration (40 feet tall, 12.2 meters) with a 64-burner arrangement of four burner groups
of 16 burners per cell. In this application, the customer wanted ultra Low NOx numbers. The
heat density in the furnace was over 350,000 Btu/Hr-ft2 with the total heater duty of 640
MMBtu/hr. Once the heater was lined out in accordance with the operating parameters, the NOx
was measured at 0.036 lbs/MMBtu (25.9 ppm) by a third party with only trace amounts of CO (less
than 1.0 ppm).
