Hotwork Recuperative Burner (HRB)

Hotwork Recuperative Burner

With typical air preheats in excess of 1/3 of the furnace operating temperature, the Hotwork Recuperative Burner has the ability to recover energy by exhausting hot waste gases through its specially designed quarl and over an integral metallic heat exchanger which, in turn, preheats incoming combustion air. This heat recovery significantly reduces the amount of fuel required for the process and makes the HRB Burner ideal for applications where flue gas temperatures are high and load residence time at high temperature is long, such as forging and heat-treatment furnaces or batch-type furnaces.
