Summary: Learn how the Steamax Oil-to-Biomass Retrofit (OBR) Kit works, its key features, potential cost benefits, and the key factors to consider before converting an existing boiler.
As fuel demand rises, industries face increasing pressure to manage energy costs and adopt more sustainable alternatives. Biomass is one option worth considering, particularly for businesses looking to reduce their dependence on conventional fuels.
Steamax offers the OBR Retrofit Kit, designed to convert suitable existing fossil-fuel-fired boilers to run on biomass. Instead of replacing the entire boiler, industries can reuse existing equipment and reduce the cost and disruption of installing a new system.
Key Features of the OBR Retrofit Kit
- Boiler conversion: Designed to adapt eligible existing boilers for biomass firing, subject to a technical assessment.
- Pollution control: Suitable pollution-control equipment can help manage emissions. Compliance must be confirmed through testing against the applicable local standards.
- Fuel flexibility: Depending on the installation, the system may allow switching between biomass and conventional fuels. The conversion and changeover time should be confirmed for the specific boiler.
How Does the OBR Kit Work?
The OBR Kit integrates a biomass combustion system with a suitable existing boiler. The main steps include:
- Boiler assessment and modification: Engineers assess the existing boiler, burner arrangement, operating pressure, capacity, and fuel requirements before planning the retrofit.
- Automated fuel feeding: A feeding system supplies biomass to the combustion chamber at a controlled rate.
- Combustion and air supply: Primary and secondary air support combustion and help direct hot gases through the boiler’s heat-transfer surfaces.
- Ash and emissions management: Biomass produces solid ash, so reliable operation requires appropriate ash handling, tube cleaning, and pollution-control arrangements.
The final configuration depends on the boiler design, biomass properties, required steam output, and site conditions.
Benefits of the Steamax OBR Retrofit Kit
1. Potential Fuel Cost Savings
In some applications, biomass may cost less than diesel, furnace oil, or other conventional fuels. Steamax has promoted substantial savings through OBR installations, but actual results depend on fuel prices, calorific value, moisture, boiler efficiency, and operating conditions.
2. Automated Fuel Feeding and Ash Removal
Automation can reduce manual fuel handling and routine ash-management work. It can also support more consistent fuel supply and combustion when the system is properly operated and maintained.
3. Reuse of Existing Boiler Equipment
A retrofit may avoid the expense of purchasing an entirely new boiler. However, engineering assessment must establish the boiler’s suitability, and modifications must comply with applicable safety and statutory requirements.
4. Lower Dependence on Fossil Fuels
Using biomass can reduce reliance on conventional fuels. Its overall environmental benefit depends on the fuel’s origin, moisture content, transport, combustion efficiency, and emissions-control performance.
5. Technical Support
Steamax supports its OBR systems. Before installation, confirm the scope of commissioning, maintenance, spare parts, and after-sales service for your specific project.
Is the OBR Kit Right for Your Industry?
An OBR retrofit may be worth evaluating if your facility:
- Operates an eligible oil- or gas-fired boiler.
- Has a reliable supply of suitable biomass fuel.
- Wants to reduce dependence on conventional fuels.
- Needs to manage fuel-handling and ash-removal labour.
- Wants to evaluate a retrofit before investing in a new boiler.
A proper feasibility study should compare expected fuel costs, boiler efficiency, biomass availability, emissions requirements, installation costs, and operating risks.
Frequently Asked Questions
The Oil-to-Biomass Retrofit Kit is designed to adapt suitable existing fossil-fuel-fired boilers for biomass combustion, potentially avoiding the need to replace the entire boiler.
No. The OBR kit removes the old oil or gas burner and mounts an external biomass combustion furnace onto the existing boiler structure, keeping capital expenditure down to a fraction of a new system.
The OBR Lite system accommodates uniform biomass fuels like Astillas & wood pellets. OBR Max can be custom designed to burn agricultural residues and briquettes. If you would rather not manage fuel at all, Steamax can supply clean biomass fuel with a steady calorific value and low moisture and ash.
Biomass makes more ash and dust than oil or gas, so every kit comes with air pollution control, such as a bag filter or an ESP. We keep particulate matter below 50 mg/Nm³ on biomass. Ash removal and tube cleaning keep heat transfer efficient.
It depends on the size of your equipment, the fuel you want to burn and the OBR version. As a guide, a conversion costs 60 to 70% less than a new biomass boiler. Or pay nothing upfront under BOOT. Tell us about your boiler or heater and we will quote.
