Mülheim/Ruhr, Germany (24.–25.03.2011)
For the first time, Lechtenberg & partner organized a dedicated
workshop focusing on the processing, storage, dosing
and feeding of refuse derived fuels (RDF). With a limited number
of 30 attendees from more than ten countries, the leading
European equipment suppliers spoke about their experiences
and explained new technology developments to international
representatives of mayor cement and lime producers.
Held at the premises of Lechtenberg & partner in Mülheim/
Ruhr, Germany, first an overview of existing technologies
and developments was given by D. Lechtenberg. He spoke
about common practices in processing of various types of
waste – starting from municipal wastes to industrial wastes.
H. Domenig, sales manager of Lindner Recyclingtech, Austria,
then showed references of existing RDF production plants
build by cement groups all over Europe. Domenig explained
the concentration of core business in shredding technologies.
Also the presentation from J. O. Simonsen, sales manager
at Metso Denmark A/S, showed a concentration on core
business: reliable and heavy duty preshredder for all types
of waste. A question by an attendee about the presence of
foreign parts within the waste was answered by Simonsen
with a short, impressive film: a whole car incl. engine was
dumped into the shredder and cut in small pieces.
The influence of refuse derived fuels in the clinker production
was explained by Dr. H. J. Diller, responsible director of the
chemical department at Lechtenberg & partner. Low moisture,
a defined grain size, low ash content and a low presence of
chlorine, sulphur and other trace elements with a high calorific
value are the preferable quality characteristics of RDF.
D. Lechtenberg from Lechtenberg & partner opened the conference by giving a presentation about existing technologies and developments
With the “King of Shredders” explained by P. Wallenius and
J. Kaaresmaa of BMH Technology Oy, Finland, was shown
an opposite company strategy: delivering the whole range of
processing, storage, dosing and feeding technologies with
capacities of up to 100 t/h of waste. A new plant build by
BMH with a capacity of 750000 tonnes of municipal solid
waste into RDF was just opened in Singapore. The design
of high and large storage silos of up to 30 m height and
20 m in diameter was controversial discussed – as Lechtenberg
was explaining before the height of RDF storages
needs to be limited due to compression, and danger of self
ignition to max. 5 m without extra fire protection and explosion
proven equipment.
M. Mikulec, director of the Schenck Process Test center
in Prague, and B. Neumann, vice president of Schenck
Process in Darmstadt, Germany, explained in a very interesting
presentation their wide range of experienced technologies
for alternative fuels storages, dosing and feeding. The
new development of a screw weigh feeder allows even the
exact ad continuous feeding of huge capacities (more than
20 t/ h). A. Kuralt of FLSmidth Pfister in Augsburg, Germany,
gave a comprehensive argument why Pfister is specialized
on dosing systems: hundreds of reference plants all over
the world using the Pfister rotary weigh feeder for dosing
alternative fuels. At last Dr. L. Di Matteo of Di Matteo
Fördertechnik in Beckum, Germany, explained his role in the
developing alternative fuel market. The family owned company
develops scientific technologies for storage and feeding.
Most interesting were his explanations about maximum
silo sizes for storage of RDF.3
