In combined cycle power plants and industrial waste heat recovery systems, the HRSG duct burner (Heat Recovery Steam Generator supplementary firing system) is critical for boosting steam production and managing load flexibility.
Choosing a professional HRSG duct burner manufacturer directly impacts your system's energy efficiency, operational stability, emission compliance, and long-term maintenance costs.

Project engineers and procurement managers should evaluate manufacturers using these six core indicators.


1. Technical Qualifications & Industry Certifications

HRSG duct burners operate continuously in high-temperature, high-velocity flue gas environments. This demands strict material integrity and precise combustion control.
  • Mandatory Standards: Verify the manufacturer holds ISO9001, CE, and country-specific special equipment production licenses.

  • The DYDTEC Advantage: Established in 2008, DYDTEC maintains ISO9001 quality management and CE certifications, backed by over 30 patented technologies in specialized combustion systems.

2. Low-NOx & Clean Fuel Combustion Capabilities

Stringent global environmental regulations make low-NOx emissions a non-negotiable benchmark for HRSG systems.
  • Evaluation Criteria: Look for proven performance in low-NOx output and future-proof fuel flexibility (such as hydrogen integration).

  • The DYDTEC Advantage: DYDTEC’s low-NOx burners suppress emissions down to 30mg/m³. The system supports advanced clean energy applications, including pure hydrogen combustion, hydrogen-blended stable combustion, and oxygen-free flameless uniform combustion up to 1200°C.


3. CFD Simulation & Customized Engineering Design

Standard, off-the-shelf burners cannot achieve optimal performance because every HRSG features unique duct dimensions, flow distributions, and temperature fields.
  • Evaluation Criteria: The manufacturer must possess in-house Computational Fluid Dynamics (CFD) simulation capabilities to model flame patterns and velocity vectors before fabrication.

  • The DYDTEC Advantage: Through strategic R&D collaborations with world-renowned universities, DYDTEC uses advanced CFD modeling to customize burner layouts, ensuring uniform temperature profiles and eliminating flame impingement on boiler tubes.

5. Large-Scale Production & Proven Field Experience

Paper qualifications must be backed by physical manufacturing capacity and a solid field track record to handle complex, large-scale utility projects.
  • Evaluation Criteria: Assess factory square footage, engineering team size, and financial stability.

  • The DYDTEC Advantage: DYDTEC operates an 11,000 m² R&D and production base staffed by over 150 specialized engineers. With annual sales exceeding 200 million RMB, the company delivers the financial scale and manufacturing throughput required for major industrial infrastructure.

6. Full Lifecycle Turnkey Services

Post-installation support is critical for avoiding costly plant downtime, especially in remote or overseas project locations.
  • Evaluation Criteria: Ensure the vendor provides comprehensive services spanning selection, design, system commissioning, spare parts logistics, and field maintenance.

  • The DYDTEC Advantage: DYDTEC provides a massive ecosystem of over 10 major categories and nearly 100 burner series (including gun-type, linear, low-NOx, hydrogen, and oil-fired options). This extensive product footprint is supported by 46 global service locations, ensuring rapid on-site technical response times worldwide.
