Frequently Asked Questions

Answers to common technical and commercial questions about our burner and boiler systems.

Our industrial burner range covers 30 kW to 14,000 kW thermal output. This includes light-duty commercial burners for small boilers, medium-capacity modulating units for process heating, and high-capacity installations for district heating and heavy industry. Each burner is sized and configured to match the specific thermal load and fuel type of the application.

Yes. Our dual-fuel burners support seamless switching between natural gas and light oil (diesel) without manual intervention. This provides fuel supply security for critical installations where uninterrupted heating is essential, such as hospitals, food processing plants, and district heating networks.

All RielloPro burners are designed to meet or exceed EN 676 (gas burners) and EN 267 (oil burners) European standards, as well as local emission regulations in North America (EPA, regional air quality standards), the Middle East, and Asia-Pacific markets. Our low-NOx models incorporate flue gas recirculation (FGR) and staged combustion to achieve ultra-low emission levels.
