Honeywell Eclipse ThermJet Self-Recuperative or TJSR Burners combine a high velocity flame with fuel saving recuperation.

The low NOx TJSR V5 is a direct fired, self-recuperative burner built with Eclipse’s industry proven ThermJet technology. Featuring advanced burner design, these burners combine a high velocity flame with fuel saving recuperation. A space-saving integral educator pulls the furnace exhaust through an internal ceramic recuperator.

The recuperator preheats the incoming combustion air to high levels, which improves furnace efficiency in reducing fuel by as much as 50% over typical ambient air burners. The TJSR V5 design also eliminates the need for hot air duct work normally required by external recuperators, providing additional savings in hardware and installation. The internally insulated heat exchanger and exhaust housing hold heat in the recuperative section, thus increasing heat recovery efficiency.


Typical applications: tempering furnaces, hardening furnaces, reheating furnaces, fluidized bed driers, thermal oxidizers, non-ferrous melting, ladle/tundish, glass lehrs, environmental applications, and preheated air.

Ask us for engineering or product support to configure your burner.
