Claudius Peters Clinker Cooler - ETA Cooler
After 50 years experience in conventional grate coolers Claudius Peters continues to develop latest generation clinker coolers to excel over and above the features of older clinker cooler technologies.
The Claudius Peters ETA cooler represents the 5th Generation of Clinker Coolers.
Worldwide it is considered to be the most technically advanced clinker cooler available today, reaching clinker capacities from 500 t/d to 13 000 t/d.
The ETA cooler consists of an HE-module (static inlet) in the kiln drop zone and standard units with horizontal arranged lanes, and enables operation with a higher clinker bed than conventional clinker coolers. This improves the function of the heat exchanger and generates a significantly higher degree of efficiency than with conventional grate coolers and beam coolers.
The compact design is a perfect fit perfectly for both Greenfield projects as well as cooler replacements for wet and dry kiln systems. The ETA cooler is particularly suitable for the use of Waste Heat Recovery(WHR-) systems and recirculation (i.e. Duotherm-) Systems. Owing to a high degree of efficiency, and the associated high and stable recuperation temperature due to the high clinker bed, the ETA cooler is particularly suitable for the sustainable use of alternative fuels (secondary fuels) and supports an increasing replacement of primary energy sources.
Since 2004, Claudius Peters’ ETA clinker cooler technology has successfully been supplied worldwide to many leading cement producers.
