Replacing Vertical Shaft KilnsCosts & Benefits
|Parent Process: Clinker Making|
|Energy Savings Potential||
Savings up to 2.4 GJ/t clinker can be obtained.
Savings of 1.6-2.0 GJ/t clinker are reported from India depending on pre-heater/pre-calcination system configuration
|CO2 Emission Reduction Potential||
In China, CO2 emissions can be reduced by 227 kg/t clinker by converting VSKs to pre-heater/pre-calciner kilns.
Costs of such conversions can be between US $28-41 per annual ton of clinker production.
Replacing Vertical Shaft Kilns 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.
