Direct Fired Heaters

Manufacturing API 560 Fired Heaters

Fired-heaters play essential roles in oil and gas industries. FEPCO, acquiring the knowledge developed in HEDCO, is able to design, construct, and commission the following type of heaters according to API 560;

  • Crude Oil Heater
  • Vacuum Charge Heater
  • Regeneration Gas Heater
  • Start-up Heaters for Petrochemical Industry

However, FEPCO also benefits from its joint venture with well-known fired heater suppliers; and therefore, is able to manufacture various types of process heaters, such as pyrolysis cracking, and vis-breaking.

Fired Heater 1

Process fired heaters consist three major parts; radiant section, convection section, and stack. Burners are utilized in the radiant section to control the firing of the fuel with air, keeping the flame stable. Heat is majorly transferred to the tubes by the means of radiation in this section. In the convection section, heat is absorbed from the flue gas passing over bare and finned tubes. Stack is used to ensure the required draft for burners and guarantee the proper flow rate of the flue gas. Due to safety requirements, the burner management system is subject to strict design and manufacturing standards.


FEPCO has achieved the know-how of designing heaters including thermal and process design, mechanical and structural design, and the fire control system. FEPCO provides the following services

  • Thermal and process design of the heaters

    • FEPCO uses its in-house codes as well as FRNC-5 and Heater560.
  • Mechanical design and prefabricating radiant coils according to API 530.
  • Mechanical design, fabricating, and modularizing the convection section according to API 530 and ASME Sec. I for SSH coils.
  • Design and fabricating steel structures.
  • Mechanical design and prefabricating manifolds, X-over, and transfer-line.
  • Design and fabricating fuel skid and implementing the firing control system including BMS according to API 556 and NFPA 85.
  • Design and installation of refractories.
  • Site supervision during erection, commissioning, and start-up.
  • Revamping of the in-service heater in order to

    • Increase the plant life-time
    • Increasing the efficiency
    • Resolve the safety issues
    • Reducing the costs of maintenance
