Abstract

This paper is focused on means of reducing consumption of electricity in the Tanzania iron and steel industries so as to save energy through preheating Technology. The iron and steel industry is one of the largest energy consuming manufacturing sectors in Tanzania due to the fact that the technology used is old and inefficient. Furnaces used to melt iron scrap consume high electricity which is around 0.85 MWh/Ton. Electricity demand does not fulfill the country need since there is frequent unexpected power cut offs all over the country. The paper analyses maximum temperature of furnace and maximum temperature of hot gases so as to determine the energy lost through these flue gases and recovering them. However, the future outlook necessitates looking into ways of developing the backup systems for the country to utilization all other alternative sources to save energy. From the results the energy saved during preheating technology is 21.63% of the total energy used. This is the target recovered in this paper.
