Presentation Title Aluminum Melting Furnace Pressure Control
Author(s) Edward M. Williams, Don Whipple
On-Site Speaker (Planned) Edward M. Williams
Abstract Scope Maximizing throughput and minimizing costs during the aluminum melting process requires measuring and controlling several operating process parameters. Furnace pressure during melting is one that is often overlooked or not controlled closely enough, but is very important to efficient operation. Furnace operating pressures that are too low can result in significant outside air coming into the furnace, consuming part of the energy input to the furnace and slowing down the melting process. Excessively high furnace pressures can result in stingers or hot gases exiting the furnace from undesirable locations, potentially resulting in equipment damage and health hazard. The benefits of maintaining proper furnace pressure control during typical melter operation have been calculated. Additionally, a variety of different types of equipment to both measure and control pressure in melter furnaces are available and will be reviewed.
