Dual-fuel burners (such as oil-and-gas dual-purpose models) command a higher price primarily because they integrate two completely independent fuel supply, atomization, and control systems, resulting in significantly increased technical complexity and manufacturing costs. The specific reasons can be summarized as follows:
Redundant System Design: Internally, the equipment effectively integrates two distinct combustion systems—one for fuel oil and one for natural gas. Consequently, it requires the installation of two separate sets of valve trains, piping, nozzles, and leak detection devices.
High-Precision Switching and Control: The burner must be equipped with advanced electronic proportional control systems and PLC control modules to ensure precise control of the air-fuel ratio, maintain thermal efficiency, and meet low-NOx emission standards when operating on either fuel.
High Material Requirements for Core Components: Fuel oil combustion requires atomizing nozzles, whereas natural gas combustion requires multi-port or mesh-type burner heads. To ensure compatibility with both media, critical core components—such as the burner lance—must be fabricated from high-grade, specialized alloy materials capable of withstanding extreme temperatures and corrosion.
Higher R&D and Commissioning Costs: Dual-fuel burners necessitate complex combustion performance testing to ensure a smooth and safe transition from one fuel to the other without causing flame-out or flashback; consequently, the costs associated with R&D and testing are substantially higher than those for single-fuel burner models.
Although dual-fuel burners entail a higher initial investment, they enable users to switch flexibly between fuels in response to fluctuating energy prices, thereby ensuring the continuity and reliability of their energy supply.
