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 PFC2 clinker 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 pollutant emission reduction.
New KHD technology core components are:
three new preheater cyclones
new preheater ID-fan
Tertiary air duct
Pyrotop compact 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 PFC2 clinker 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. Commissioning of the new system is scheduled for April 2019.
