Energy Audit and Conservation Measures in a Ceramics Factory in Kogi State

This project conducts an energy audit of a ceramics manufacturing factory in Kogi State, North Central Nigeria, with the objective of identifying energy consumption patterns and recommending feasible conservation measures. Energy costs represent a significant proportion of total production costs in ceramics manufacturing due to the high thermal requirements of kiln firing and the substantial electrical demand of ball mills and spray dryers. This study employs a walk-through energy audit methodology supplemented by detailed metering of electricity and fuel gas consumption across major equipment categories. Data were collected over a four-week audit period using calibrated power meters and gas flow meters. Energy performance indicators are computed and benchmarked against published data for comparable ceramics facilities in sub-Saharan Africa. Results reveal that kiln operations account for sixty-seven percent of total energy consumption, with significant losses attributed to refractory degradation and suboptimal firing cycle programming. Compressed air leakage in the spray dryer section is identified as an additional source of avoidable energy waste. Recommendations include kiln refractory refurbishment, installation of variable frequency drives on high-load motors, and implementation of an energy monitoring system for real-time consumption tracking. Estimated annual energy cost savings from proposed measures are calculated at approximately eighteen percent of current expenditure.
