New Dust Burner: Unique
System Solution for Special
Customer Requirements.
With increasing frequency customers are requesting special solutions, as
did M/s. Loesche in Düsseldorf. For a plant project in Russia they were
looking for a firing system which took particular fuel specifications into
consideration. With a large-scale firing test in the testing facility of Körting
Hannover AG it was possible to test the suitability of the fuel successfully.
The Düsseldorf mill specialist
Loesche was on the look-out for
a dual-fuel burner system to fire
lignite dust and heavy oil for a
dryer plant. The problem thereby
was, however, the characteristics
of the coal dust which
deviated in its chemical
composition from the usual
characteristics. First of all,
a firing test was carried out
at the Körting dust burner
test facility to ensure the
technical feasibility of the
project. “By means of the
