Cologne based Humboldt Wedag GmbH has been awarded an EPC contract by Rohrdorfer Cement Group for the kiln line modernization at its cement plant operations in Gmunden, Austria. The kiln modification will enable the very flexible usage of a wide range of waste fractionally pre-treated derived fuels on a high substitution rate.

The modernization project comprises the design and supply of KHD's world´s first ever PYROROTOR Calciner Technology as well as the replacement of the existing satellite cooler with a new generation PYROFLOOR PFCclinker cooler. The existing three station rotary kiln will be fitted with a new kiln drive and a new kiln hood as well as kiln inlet and outlet.

With the installation of the new PYROROTOR Calciner Technology from KHD the Gmunden plant will be able to burn very coarse waste derived fuels including whole rubber tires, which will lead to drastically reduced requirements in regard to waste pre-treatment. Therefore, the kiln modification will also emphasize on pollutant emission reduction.

New KHD technology core components are:

- 3 new preheater cyclones
- new preheater ID-fan
- Tertiary Air Duct
- PYROTOPcompact Calciner mixing chamber
- PYROROTOR Calciner burning chamber technology
- PYROCLON Calciner Burning System
- new Kiln Bypass Unit
- multi-fuel PYRO-JET kiln burner for primary and secondary fuels
- new kiln drive and kiln hood
- PYROFLOOR PFCclinker cooler equipped with a PYROCRUSHER roller type clinker crusher
- SIMULEX plant simulation software
KHD services include the dismantling of existing equipment parts as well as the engineering, design, supply and erection of new equipment incl. commissioning services.

Combining KHD's proven pyro-processing technology with its cutting-edge alternative fuel burning technology with, this project underlines KHD's environmental technologies and leading market presence on innovative technologies in the cement industry for more than 160 years.

Commissioning of the new system is scheduled for April 2019.
