In this work the design and thermal performance rotary furnace for melting of secondary alu-minum. The estimation of combustion quality, compiled heat balance and furnace operating mixer. The measures according to technical improvement of the furnace in order to reduce fuel consump-tion, the melting duration, reducing the dust loading, reduce air leaks: reducing air leaks due to seal the joint between the burner device and a porthole, reconstruction slag chambers rotary furnace by increasing the volume of the chamber and install septum installation ZN-cyclone group 15-800-4UP installing a slag chambers tract and rotary kiln metallic recuperator for heating air for combustion of the fuel, the organization of innings Fuel cells via injection burners during filling. When implementing the proposed technical improvement is expected to decrease the load on the dust filter bag, the length reduction smelting, fuel economy, reducing air leakage.
