Direct Fired Heaters

OTSO Direct Fired Heaters are unique, as they heat process fluids via a firetube, rather than a process coil. The firetube is typically located at one end of the vessel, where incoming fluid is heated directly. Named by the service they perform, heater types include oil treaters, FWKOs, and regenerators (for glycol and amine applications). Similar to indirect fired heaters, the heat transfer rate ranges from 50,000 Btu/hr. to over 13 MM Btu/hr.—in some cases, it can reach as high as 15 MM Btu/hr.

Note that process temperatures are determined by the process fluid, and may also differ depending on the heater. We offer special firetube design to handle your heat requirements.
