WS is a globally leading manufacturer of high-efficiency and low-emission self-recuperative and self-regenerative burners for the steel and heat-treating industries. We are proud to be the inventors of the game-changing Flameless Oxidation (FLOX®) technology, which enables high air preheat temperatures with low NOx emissions.

Across nearly every industry and region of the world, OEMs and end users are looking for ways to improve their heat-treat equipment and processes. They are facing increasingly stringent NOx emissions regulations while also being challenged to be more eco-friendly by reducing fuel usage and lowering their carbon footprint.

This article discusses different types of direct-fired gas burners that can be used for high-temperature applications.

A case study at Eck Industries in Manitowoc, Wis., shows the fuel savings realized by the addition of a self-recuperative burner to crucible melting furnaces.
