HS v2022 Code: 841620

About furnaces; furnace burners, for pulverized solid fuel or gas, including combination burners

HS code 841620 covers a critical component of industrial and commercial heating systems - furnace burners. These burners are essential for the efficient combustion of pulverized solid fuels or gas, providing the heat required for a wide range of industrial processes and building heating applications. As a key part of the 841600 Furnaces and Burners industry, these burners play a vital role in supporting manufacturing, energy production, and infrastructure across the global economy.

Production process

Furnace burners are typically manufactured through a combination of precision engineering and advanced materials processing. The production process often involves the fabrication of burner components such as nozzles, air inlets, and ignition systems, which are then assembled into complete burner units. Specialized techniques like metal casting, welding, and machining are commonly used to shape and assemble the various parts. Rigorous testing and quality control measures are also essential to ensure the burners meet safety and performance standards.

Production inputs

The production of furnace burners requires a range of inputs, including metal alloys for the burner components, refractory materials for heat-resistant linings, and electronic controls and sensors. Specialized machinery, such as CNC machining tools and welding equipment, are also necessary for the manufacturing process. Additionally, the industry relies on a skilled workforce with expertise in mechanical engineering, materials science, and industrial automation.

Production outputs

The primary output of HS code 841620 is the furnace burner itself, which is then integrated into larger 841600 Furnaces and Burners systems. These burners are used in a wide variety of industrial and commercial applications, including power generation, manufacturing, and building heating. The output of this industry is often consumed by other industries, such as 840410 Auxiliary plant for use with boilers and 841780 Industrial or laboratory furnaces and ovens, which incorporate the burners into their own products and systems.

Revisions to 841620
