Revamping

Revamping Fired Heaters

Revamping fired heaters is a practical and effective way to improve heater performance. This focuses on working with existing components and as a result, investment and downtime is minimized. Revamping provides : 

  • Longer Run Lengths

  • Capacity Increase

  • Efficiency Improvement

  • Lower NOx Emissions

A fired heater revamping project typically has the following phases:

Phase I → Engineering Study +/- 30% Cost Estimates.
Phase II → Project Design Basis Report with +/- 10% Cost Estimates.
Phase III → Detailed Engineering and Project Services.

Furnace Improvements’ scope of services includes but is not limited to:

  • Engineering

  • Project Management

  • Procurement

  • Fabrication

  • Site Services

FIS office in Delhi carries out mechanical and structural design work, detailed engineering, and provides support for other disciplines. Due to the time difference between US and Indian offices, work gets done around the clock.

FIS Technologies

Heaters have many common problems such as low capacity, high tube skin temperature, coking issues and bad burner flame. To combat these issues FIS developed and patented different technologies.
