Our Dilute Oxygen Combustion (DOC) technology is an award-winning technology that represents the next generation of flameless oxygen-enhanced combustion for steel reheating. This application provides you with a flexible, low-cost way to convert burners from air-fuel to oxy-fuel systems. It can increase productivity, decrease fuel consumption, lower operating costs and reduce emissions. 

Conventional air-fuel burners inject significant amounts of nitrogen that get heated and exhausted from the furnace, resulting in unnecessary heat and energy losses. DOC technology uses oxy-fuel burners that eliminate the air — and therefore, the nitrogen. The benefits of this alternative process may include fuel savings of up to 50%, productivity increases of up to 35%, reduction in NOx and CO₂ emissions, and improved heating uniformity. And you can get all of these benefits in a simple, low-maintenance system. DOC burners are extremely compact, even allowing them to be retrofitted within the existing air-firing system of your metal production facility. This unique advantage provides operators with ease of installation and the flexibility for on-demand operation. 

Our DOC technology has been installed in hundreds of different furnaces worldwide, including continuous steel reheat furnaces, batch reheat furnaces for steel and non-ferrous materials, and forge furnaces. Let’s revamp your furnace for fuel savings, productivity improvements and emissions reductions.
