Infrared Metal-Fiber Burners: Selas Apollo-Ray®
AR Series burners are infrared metal-fiber burners with high radiance and all-metal construction and premix design. The Apollo-Ray is available in two sizes.
Selas Metal Fiber Gas Burners are designed for high-radiance heating in industrial applications. These burners, available in sizes 8” x 6” and 12” x 5”, feature all-metal construction and a premix design for efficient combustion. With infrared heat capacities of 22,000 BTU/hr and 30,000 BTU/hr, they offer excellent resistance to impact, thermal shock, and water damage. Ideal for tunnel ovens, food production, and other high-heat processes, Selas Metal Fiber Gas Burners ensure reliable performance and uniform heat distribution.

Operating Principles
The Apollo-Ray (AR) burner is a surface combustion, metal fiber gas-fired infrared burner. The premixed air and gas passes through the burner body and out through the porous emitter surface. Combustion takes place in a thin layer just above the outer surface.
The Apollo-Ray has a long life due to the sintered metal fiber alloy emitter. Its many micro pores disperse and entrain the air gas mixture. Once ignited, robust infrared radiance is uniformly dispersed over the emitter’s entire surface. This produces fuel savings of 20%+ over knit metal and other fiber burners. The emitter is flexible by nature but backed by a rigid support. This allows it to resist damage during routine maintenance or by thermal shock after repeated firings. When firing face down on a conveyorized product, the metal fiber mat remains flat and does not sag, unlike conventional knit metal fiber burners.
The all stainless steel construction of the Apollo-Ray burner body provides excellent heat and chemical resistance. The emitter and its baffle plate are welded to the body. These attributes make the Apollo Ray burner an ideal choice for both industrial and food grade applications. Because it is a flat-faced burner, it can be placed close to the product. Its turn down ratio is a relatively high 2.5 to 1.
Once signaled by the control panel, ignition is easy and flame propagation is fast. Ignition can be provided by a direct spark or a standing pilot. Burners can be monitored by a flame rod or a UV scanner. The burners can be attached to the manifold with standard length (1-1/2”) or long (2-3/8”) union connectors.
The gas inlet can be mounted on the side instead of the bottom producing a low profile burner. A side-mounted low profile burner is only 2-1/8” high, ideal for replacing ribbon burners to achieve higher heating efficiency. Low profile burners are also used between conveyor belts, where space constraints exist.
All Apollo-Ray burners are quick heating and quick cooling. Short heat-up and cool-down periods enhance productivity, save labor costs and prevent excessive heat loads during line stops. The burner sections can be mounted parallel (horizontal) or perpendicular (vertical) to the manifold. This allows the optimal combination of heat flux and length for different applications and line speeds.
