Abstract:
A low NOburner system is disclosed that reduces the emission of CO and HC during cold furnace startups, minimizes NOformation with preheated air, and provides a flat stable flame due to burner design improvements including three stage combustion. The burner system is designed to operate in either a low or high temperature mode by controlling the amount of combustion air provided to stage 1 and stage 2 combustion. The burner system is designed to heat the interior of a furnace for high-temperature combustion/furnace processes, such as aluminum melting and steel processes. The burner system can also be used for low temperature processes at temperatures below the auto-ignition temperature of the fuel and still produce very low CO, HC and NOemissions.
