Boiler retrofit
A retrofit, not a rebuild.
HydroHub™ is added beside an existing boiler. The fuel, burner, firing system and pressure parts stay as they are.
On site
What changes, and what does not.
What changes
- A generator skid beside the boiler.
- A gas line to the combustion air path.
- A tie-in to the burner management and interlock system.
What does not change
- Fuel.
- Burner.
- Firing system.
- Boiler pressure parts.

Lifecycle
Six stages from assessment to support.
- 01
Assessment
Paid site or enterprise assessment from operating data. - 02
Design
Sizing, injection point, dosing and interlock specification. - 03
Integration
Installation by the customer's local execution party, to YBG design. - 04
Commissioning
Interlock proving and controlled start-up. - 05
Validation
Baseline-to-result measurement on steam-to-fuel ratio. - 06
Support
Ongoing technical support as design authority.
Assessment data
Data we need for an assessment.
- Boiler make, type and rating
- Fuel and gross calorific value (GCV)
- Steam output and pressure
- Fuel consumption
- Load profile
- Combustion air / FD fan data
- Flue gas analysis
- Electricity cost
Injection point
Engineered from your combustion data.
The injection point and dosing are engineered from the site's own combustion data during assessment, and incorrect injection points are a common cause of poor results elsewhere.

Assessments are paid engagements. We confirm scope and fee after reviewing your plant data.
