The Eclipse Furnnox burner is a direct fired furnace burner designed for continuous high-temperature processes—such as in the steel industry—offering exceptionally low emissions. In most high-temperature applications, Furnnox burners can achieve NOx emissions below 30 ppm at 3% O₂. To ensure optimal efficiency, the burner maintains the correct air-to-fuel ratio across its full operating range. It is available in two configurations: a standard version for combustion air preheated up to 150°C, and a high-temperature version with an insulated housing, capable of handling preheated air up to 600°C. The Furnnox supports direct ignition throughout its full ignition and operating range without requiring a pilot light. Typical applications include electroplating furnaces, forging furnaces, and heat treatment furnaces. To achieve low NOx emissions, the combustion chamber must operate with less than 5% O₂. Reducing excess air and lowering oxygen levels in the chamber further improves NOx performance.
