Industrial Burner Retrofit Engineering

Signs an Industrial Burner System Needs Engineering Retrofit

Legacy industrial burners degrade, become obsolete, and fall out of regulatory compliance. A structured burner retrofit engineering package is required when annual value seat tests are failing, no stamped engineering drawings exist, relay-based BMS panels are no longer maintainable, TSSA Field Approval has expired, or a fuel type change is required.

What a Burner Retrofit Engineering Package Includes

  • Existing System Documentation and Gap Analysis: As-built P&IDs and identification of non-compliances with current CSA B149.3, NFPA 86, and TSSA requirements.
  • New Burner Integration and Flame Geometry Modeling: Verifying new burner flame length and profile are compatible with existing combustion chamber geometry.
  • Updated Fuel Train and Valve Train Design: Adding missing POC switches, replacing single SSOVs, or updating the atmospheric vent line.
  • Modern BMS Panel Design: Replacing legacy relay panels with Honeywell 7800 Series, Fireye BurnerLogix, or Siemens LMV flame safeguard controllers.
  • TSSA Field Approval Package: Complete stamped submission ready for TSSA Client Portal.

Frequently Asked Questions

Can the existing furnace shell be retained during a burner retrofit?
In most cases, yes. Burner retrofit packages routinely replace the burner, valve train, and control panel while retaining the existing furnace shell and refractory lining.
