Our APCOS™ technology is a tuyere-based system that operates in conjunction with a cupola's current blast air. It uses a proprietary burner design that injects supersonic oxygen and natural gas to replace coke, allow coke substitutions and/or increase production. The APCOS burner can also accommodate solids injection through the burner, with the heat of the oxy-fuel flame allowing significant solids injection without cooling the melt zone. The rapid response of heat and solids injection at the tuyere offers operators a great tool to control the cupola and recover from upsets. The APCOS burners can be controlled individually or as a group and burners can be placed in a single tuyere, alternate tuyeres or all tuyeres. The burner is designed to allow optimal heat release and supersonic injection across a wide range of heat inputs. The flow controls for the burner's system and safety interlocks can be integrated into the cupola control system and feature data acquisition and reporting capabilities.
