Abstract
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.
Claims20
A slag foaming system for an electric arc furnace utilizing a renewable source of carbon comprising:
- a) an electric arc furnace;
- b) a slag foaming delivery system comprising:
- i) a slag foaming composition comprising algae wherein the algae includes algae particles;
- ii) an algae receptacle for said algae;
- and
- iii) an algae injector for injection of the algae from the algae receptacle into said electric arc furnace,
- wherein the algae provides said renewable source of carbon for production of a carbon dioxide from the electric arc furnace.
