Cement Energy and Environment

~ baselines were defined for different levels of units. Total energy consumption in terms of TEP per 100 Tons of cement production was defined as 1st energy performance indicator. The average of specific energy consumptions in past 4 years was defined as the 1st energy baseline (Figure 1). Since CEM I is the most widely produced cement type, specific electrical energy to produce FABRIKA ENERJIPERFORMANSI •TEP/100 Ton ~lmento 1000 JIQI) • '400 7000 I oct Figure 1. 1st Energy Performance Indicator and Energy Baseline of Plant lO!J (EM I was defined as the second Energy Performance Indicator. The average of specific electrical energy consumptions in past 4 years was defined as 2nd energy baseline (Figure 2). Other important energy performance indicators and baselines are given in Table 5 and Figures 3 and 4. IU 1\lo ... Ill . ..

All energy analyzers have communication with CCR automation system via fiber cable infrastructure. 50, energy consumption data flows in automation system on– line. Energy consumptions data of each unit ~nd · significant equipment are stored in the system as "kWh". 13
