A slag foaming system for an electric arc furnace utilizing algae is described. The algae may be dried algae in particle form that is injected into the electric arc furnace through a solids injector and may be directed into the slag. Other slag foaming compositions may also be injected into a furnace as a function of furnace parameters to create slag foam while maintaining a high yield of slag without excess iron oxide and reduced carbon and carbon dioxide emission. The algae and slag foaming composition may be used in combination for slag formation and control.

A furnace cooling panel monitoring system utilizes individual cooling panel data to produce critical monitoring data. An exemplary cooling panel monitoring system utilizes the input from a plurality of temperature sensors configured to accurately measure the temperature change of cooling fluid flowing through each individual panel. The change in temperature from the inlet to the outlet of a cooling panel along with the flow rate of the cooling fluid through the panel can be used to calculate the a heat energy dissipation rate of the cooling panel, or heat flux. The flow rate through individual panels is determined by K-values or resistance to flow constants for a given cooling panel. The heat energy dissipation rate for individual panels can be provided to a user through a computer implemented monitoring program in real time. Alerts may be initiated by the computer implemented monitoring program when a threshold value has been exceeded.
