Application of Harsvert VFD in Zibo Cement Plant
2009-12-15 13:59:51
Our plant began to use VFD in 2004 and it saved much cost for our plant. We use 8 sets of Harsvert VFD in Zibo Cement Plant reconstruction project. We make a statistic for the project effect. The data is in following table:
Field | Motor power kW | Motor power (before) kW | Motor power (after) kW |
1# circulating fan, line1 | 1000 | 790 | 661 |
2# circulating fan, line1 | 1000 | 774 | 681 |
High-temperature fan, line 1 | 2500 | 2221 | 1777 |
Mill fan, line 1 | 630 | 348 | 247 |
3# circulating fan, line2 | 1000 | 830 | 681 |
4# circulating fan, line2 | 1000 | 780 | 632 |
High-temperature fan, line 2 | 2500 | 2420 | 1866 |
Mill fan, line 2 | 630 | 388 | 257 |
Energy-saving Calculation:
Yearly work time: 11 months, month work time: 28 days. Total work time is 7392 hours.
For line 1:
Save power=(790-661)+(774-681)+(2221-1777)+(348-247)=767kW
Yearly save power=767×7392h=5669600kWh
Yearly save cost=5669600kWh×0.5yuan/kWh=2834800yuan (USD 416882).
Conclusion:
In brief, the reliable performance and ideal power saving effect of medium voltage VFD have created tremendous economic benefits and social benefits for the company, so it is worthy to be recommended and applied in industry.
