Show -APPLICATION- 6 TONNE/H ALUMINUM MELTING FURNACE ALCAN PLATE LTD., BIRMINGHAM, U.K. DATE OF INSTALLATION - May 1985. EQUIPMENT - Two 8 GJ/h (8 million BTU/hr) gas fired reGen "Easy Clean" high velocity units, each comprising two burners, two regenerators, a reversing valve and associated reversing logic. DESCRIPTION - The furnace is a bath charged melter, fed with a range from 6mm (1/4") p late to large ingot, having a bath area of 15 sq. m (161 sq ft.) Burners are installed in the side walls and roof of the furnace. Solid flux is used for skimming and cleaning, with nitrogen/chlorine used for degassing. PERFORMANCE - Results to date show a 29% reduction in fuel consumption, but with an 11% reduction in target melt rate. Two additional burners will be added to the end wall of the furnace opposite the door to rectify thi.s. -APPLICATION- 4.55 TONNE/H ALUMINUM MELTING FURNACE CHRYSLER CORPORATION, KOKOMO, INDIANA 84 DATE OF INSTALLATION - June 1985. EQUIPMENT - Two 6 GJ/h (6 million BTU/hr} ~as fired reGen "Easy Clean" units, each comprising two burners, two regenerators, a reversing valve and associated reversing logic. . I n order to provide resistance to corros~on by the flux I aden exhaust gases the reverSI ng valve is nickel plated and the regenerators have internally vi treous enamelled bases. D ESC R I PT ION - T his fur n ace, reb u i I tan d r etrofitted with reGen by F. W. Schaefer Inc., is a large reverberatory melting furnace, 7.92m (26') long by 4.88m (16') wide with a 77.5 t (170,000 I b) capac i ty and 4.55 t/h (10,000 I b/hr) output-. The furnace is charged into a well, or through side doors - with the burners firing over the top of the bath from one end of the furnace. Charge make up is large scrap and ingot through doors, small scrap and liquid metal into a side well. Fluxing is carried out once per shift for metal and furnace cleaning. During that operation the doors are open, the burners are at low fire, and a small auxiliary flue is opened. PERFORMANCE - The reGen System is currently providing a fuel savings of just under 40%, with further optimization expected. Cleaning of one pair of regenerators was first carr i ed out after four months of operat ion, before the regenerator resistance had risen to a point that made it necessary to do so. The second pair was cleaned at five months, there being some indication that it was necessary. Routi ne mai ntenance now calls for each pai r to be cleaned on alternate months. -APPLICATION- 0.65 TONNE/H ALUMINUM MELTING FURNACE AMCAST INDUSTRIAL CORPORATION COLUMBIA, LOUISIANA DATE OF INSTALLATION - November 1985.
