Cement Industry
METHERM® MIP(Microporous Insulatiuon Panel) used for cement industry(rotary kiln, preheater, cyclone, calciner, tertiary air duct, grate cooler, cement grinding mill).
Benefits: Huge energy cost savings and increased product output.
Please refer to the following practical case:
China United Cement Corporation(CUCC) Case
Position | Internal temperature | Insulation layer structure (from inside to outside) | Temperature of unused METHERM® MIP | Temperature of used METHERM® MIP | Temperature decrease | Energy conservation |
Preheater C3,C4,C5 | 800-1000℃ | 146mm Refractory brick + 50mm METHERM® MIP + 50mm Calcium silicate board | 80℃ | 55.5℃ | 25℃ | 324 W/m2 |
Calciner | 1000-1200℃ | 135mm Refractory brick + 50mm METHERM® MIP + 85mm Calcium silicate board | 128℃ | 65.3℃ | 63℃ | 1031 W/m2 |
Grate cooler | 1000℃ | 180mm Refractory brick +100mm refractory castables + 25mm METHERM® MIP | 150℃ | 86.7℃ | 63℃ | 1316 W/m2 |
Tertiary air duct | 800-1000℃ | 164mm Refractory brick + 50mm METHERM® MIP | 108℃ | 58.3℃ | 50℃ | 814 W/m2 |
Benefits:
1. Energy consumption: the area of METHERM® MIP used: 268x20=5360 ㎡, and the average energy consumption of 1 ㎡ is saved by 600W; Daily energy consumption: 5360㎡x0.6KWx24h=77184KW·h; Energy saving in 6 months: 77184x180 ≈ 14 million kWh;
2.Capacity expansion: 5000 tons to 5500 tons project, greatly increasing the daily cement output.
