SHELL-TEC - Infrared burners for radiant panels

Description

The SHELL‑TEC series by ESA‑Pyronics consists of high‑performance infrared burners designed for radiant panels. They are used in industrial heating processes requiring high efficiency, uniform radiant output, and adaptable flame characteristics. These burners feature a robust iron body and a special metallic fibre panel made from refractory steel alloy developed by SHELL.
lass=”yoast-text-mark” />>This metallic fibre has an average permeability of 22 × 10⁻⁶ mm, enabling excellent resistance to elevated temperatures and ensuring stable radiant performance even under severe thermal conditions.
The fibre surface can reach a maximum operating temperature of 1,150 °C, allowing the burner to operate in demanding industrial applications.

The burners are compatible with multiple fuel types including natural gas (CH₄), LPG, and propane. They operate at low gas and air pressures of approximately 40 mbar. Depending on mixture pressure and surface temperature, the panel can produce either infrared radiant heat or a traditional direct flame, providing flexibility for different process requirements. Their radiant capacity reaches approximately 300 kW/m², while conventional flame operation can reach up to 500 kW/m². The system supports high excess‑air operation, a wide turndown range, and high energy efficiency.

SHELL‑TEC burners are built to order, allowing customization of the panel’s surface area based on process needs—from compact designs to large‑scale heating surfaces. Typical industrial applications include paper drying, the heat treatment of fabrics, glass, rubber, and resins, billet heating, and food‑processing ovens. Ignition and flame detection are performed via a Wand electrode, which does not require enriching the gas‑air mixture thanks to the metallic fibre’s ability to quickly propagate flame across its structure. The pressure drop in the mixture manifold must remain below 2.5 mbar to ensure proper operation.

SHELL‑TEC burners can be installed in any orientation and can use flexible connectors for air and gas supply. Their durable construction and combustion behavior make them a reliable solution for industries needing controlled radiant heat and high‑temperature resistance.
