Boiler Revamp & Retrofit
Repair restores a boiler to its original condition. Revamp and retrofit change what it can do — more capacity, a different fuel, tighter emissions, modern controls. We scope these as engineered projects, not a parts list, and we'll tell you when the shell itself is the limiting factor rather than sell past it.
Services in this division
Boiler Revamp
Improve the system, not just restore it.
Boiler Retrofit
Upgrade the technology underneath the same footprint.
Fuel Conversion
Switch fuels without switching boilers.
Capacity Enhancement
More steam from the boiler you already have.
Boiler Modernisation
Bring the controls up to what the boiler is actually capable of.
Pollution Control Retrofit
Emission control equipment, integrated into an existing draft system.
Scope of work
Performance & capacity
- Capacity enhancement and pressure part upgradation
- Combustion, grate and burner modification
- Economiser and air preheater addition
Fuel & controls
- Fuel conversion — coal, biomass, oil, gas, multi-fuel
- Controls modernisation — DCS/SCADA/PLC retrofit
- Pollution control retrofit — ESP, bag filter, cyclone integration

| Dumping / travelling grate boiler | all makes | 5–60 TPH |
| AFBC / CFBC boiler | all makes | 5–120 TPH |
| Bagasse-fired boiler | all makes | 10–150 TPH |
| Utility / captive boiler | all makes | utility & captive scale |
How we execute
Survey
Existing performance baseline, design margins and site constraints assessed against the target outcome.
Engineering & method statement
Conversion or upgrade design, statutory approval route confirmed, method statement issued.
Mobilisation
Fabrication, procurement and site mobilisation scheduled to your shutdown window.
Execution
Site fabrication, erection and tie-ins, with hold-point inspection on pressure part work.
Handover
Commissioning, performance trial and documentation, including updated IBR records where required.
Documentation you receive
- Engineering design basis and drawings
- Statutory approval / competent-person sign-off for structural alterations
- Fabrication and erection QA records
- Commissioning and performance trial report
- Updated IBR registration documents where applicable
Typical turnaround
| Fuel conversion (coal → biomass) | 3–6 weeks |
| Capacity uprating | 4–8 weeks |
| DCS/SCADA retrofit | 2–4 weeks |
| ESP / pollution control retrofit | 4–10 weeks |
Frequently asked
Usually, for capacity and fuel-flexibility gains within the existing pressure part envelope. Once the shell itself is the limiting factor, we'll say a revamp isn't the right call rather than scope past it.
Yes. Structural alterations need Chief Inspector authorisation or competent-person supervision — handled as part of the engineering scope.
Multi-fuel retrofits are common where fuel availability is seasonal — the grate, feed system and draft are engineered for the fuel mix.
Depends on your unit's category under current emission norms — check applicability before budgeting; see the Compliance page for the current framework.
Depends on pressure part condition and draft system headroom — a condition assessment during pre-engineering gives you the real number before we commit to a design.
