Good, bad and ugly process burner flames

Baukal, C., Weimer, B., Pappe, M., Mcguire, J., Johnson, B., Luginbill, R., John Zink Hamworthy Combustion

As part of the U.S. Environmental Protection Agency’s (EPA’s) maximum achievable control technology (MACT) fired heater inspection program, the authors’ company has inspected nearly 1,000 heaters since the program started in 2015. These inspections have revealed all types of flames—the good, bad and ugly. Here, good is defined as no changes are needed; bad is defined as changes are needed where the conditions are not likely dangerous; and ugly is defined as immediate changes are needed because the conditions are potentially dangerous.
