Energy Consumption Pattern in Rolling Mill Company, Kano Northwest Nigeria

Abstract

Abstract:The electrical and fuel energy consumption for seven years period was collected for rolling mill company, Kano northwest Nigeria. Monthly energy consumption data were gathered and analyzed. The average electrical energy and thermal energy consumption per tonne of product for the period considered are 34.04GJ/Tonne and 99.74GJ/Tonne respectively. The energy end users were identified as electric furnace, DC main motor, Compressor machine, Air-conditioning, Lightning and Electrical equipment. Regression techniques were used to correlate the monthly energy consumption with product weights in Tons. The Coefficient of determinant (R2) for electrical energy consumption was 0.8458 while R2 for fuel oil energy consumption was 0.7773 indicating strong correlation for electrical and fuel oil energy consumption.
