🔥 Direct Fired TO (Pre-Heater Shell & Tube Heat Exchanger, Supplemental Burner MMBTU)

Direct Fired Thermal Oxidizer (DFTO) Calculator

Size direct-fired thermal oxidizers (DFTO / Fives / Zeeco / John Zink) handling high-concentration chemical process vent gases and chlorinated VOCs: calculate supplemental natural gas burner firing duty (MMBTU/hr), size recuperative shell-and-tube heat exchangers pre-heating incoming process gas to 1,000 deg F, and combustion contracting yields.
