New approach on energy conservation measures types applied in mining industry

摘要

Some Energy Efficiency Programs (EEP) considers Energy Use Intensity (EUI) as an unreliable indicator due to its variation, i.e. the EUI values are dropping when production increases. Currently used Energy Conservation Measures - ECMs (supported by governmental and utility programs) are proven by energy savings (ES) recorded at revenue meter (or system boundary meter) considering energy use or energy recorded at revenue meter as a whole. The author proposed a novel concept of splitting the energy in 2 (two) specific components: Productive Energy and Non-Productive Energy followed by definition of new EUI type: Productive Energy Use Intensity (PEUI). The concept, applied to metal mines, made a breakthrough in EEP, enabling new ECM types applicable in Mining Industry. Case studies with verification & validation activities are provided.
