Energy saving : re-use of exhaust gas at Wispeco aluminium’s remelt department

Abstract

South Africa is faced with a major problem regarding power supply and consumption. Companies throughout South Africa do not practice efficient energy usage although we are a country that suffers from major power outages due substandard power generation from Eskom. This document gives details regarding a project aimed at re-using heat energy in the Wispeco aluminium plant. The problem and all of its elements will be discussed and possible solutions to the problem highlighted. Further in this document emphases will be placed on the implementation of the best solution. Aspects such as the materials used and the timing of implementation will be discussed. Possible solutions to the scheduling problem at the homogenizing ovens will be discussed. Solutions and implementation methods will be illustrated. Tools and systems such as employee performance charts, light indicator systems and control charts will be implemented to assist the remelt department in reducing cost.
