Improving Fuel Usage in an Aluminium Reverberatory Melting Furnace by Using High Velocity Heavy Fuel Oil Burners. Final Report

摘要

In 1980, British Alcan Aluminium Ltd. decided to investigate the potential benefits of high-velocity burners. It was considered that optimum energy savings would only be achieved if the high velocity burners were operated in conjunction with modern instrumentation, which facilitates more efficient furnace control, and improvements were made to the refractory linings of the furnace. Calculations indicated that six high-velocity burners, together with the other improvements, could reduce fuel costs by approximately 30% and give a payback period of approximately two years. Overall, the possible future replication saving to the aluminium industry was estimated, at the start of the project, to be Pound 750,000/year. (ERA citation 12:025133)
