Low Pressure Drop Cyclones for Suspension PreheatersCosts & Benefits
|Parent Process: Clinker Making|
|Energy Savings Potential||
Power savings in the range of 0.7-4.4 kWh/t clinker depending upon feasibility of cyclone modification and fan efficiency.
In India, average savings are reported to be 1.5 kWh/t clinker.
|CO2 Emission Reduction Potential||
Use of this option may reduce CO2 emissions by 0.5 to 3.5 kg per ton of clinker produced.
Based on the average savings of 1.5 kWh/t clinker, use of this technology reduces CO2 emissions by 1.2 kg per ton of clinker produced.
The cost of a low-pressure drop cyclone system is assumed to be US $3 per annual ton clinker capacity. Installation of the cyclones can be expensive, since it may often entail the rebuilding or the modification of the preheater tower, and the costs are very site specific.

Low Pressure Drop Cyclones for Suspension Preheaters 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.
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.
