Efficient kiln drivesCosts & Benefits
|Parent Process: Clinker Making|
|Energy Savings Potential||
0.5 – 1% reduction in electricity use of the kiln drive can be achieved by replacing a DC motor with AC motor.
Using high-efficiency motors to replace older motors, or instead of re-winding old motors, may reduce power costs by 2 to 8%.
Electricity savings are 0.55-3.9 kWh/t clinker
|CO2 Emission Reduction Potential|
The capital cost for single pinion drive with an air clutch and a synchronous motor is around 6% higher than standard kiln drive.
Efficient kiln drives Publications
The U.S. Environmental Protection Agency’s (EPA) energy guide, Energy Efficiency Improvement and Cost Saving Opportunities for Cement Making, discusses energy efficiency practices and technologies that can be implemented in cement manufacturing plants. This ENERGY STAR guide provides current real world examples of cement plants saving energy and reducing cost and carbon dioxide emissions.
