Conversion of Long Dry Kilns to Preheater/Precalciner KilnsCosts & Benefits
|Parent Process: Clinker Making|
|Energy Savings Potential||
Up to 1.4 GJ/t-clinker can be saved.
|CO2 Emission Reduction Potential||
For every ton of clinker, following amounts of CO2 reductions are estimated:
132.4 kg in Chinese context;
138.5 kg in Indian context;
108.8 kg in the United States.
Upgrading costs are reported to be between US $8.6 to $29 per annual ton of clinker capacity.

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.
The report represents the independent research efforts of the European Cement Research Academy (ECRA) to identify, describe and evaluate technologies which may contribute to increase energy efficiency and to reduce greenhouse gas emissions from global cement production today as well as in the medium and long-term future.
