The programs that ACI can use to operate the HMI’s used to operate its EAF combustion technologies are as follows:
All status and alarm conditions are detected by the PLC and clearly displayed with a message on the monitor (i.e. low oxygen pressure). Any alarm must be acknowledged and corrected by the operator before the condition is cleared and operations are resumed.
The typical system interface allow definitions of up to 10 different burner modes (as holding, charging, low heat, high heat, soft lancing, hard lancing, etc.). On each mode, the supersonic oxygen gas flow and the post-combustion oxygen gas flow can be set-up independently
