industry, mixes the waste <strong>and</strong> conveys it to an area at one end of the building.
From this head area, an automated crane draws the waste to charge the
incineration system.
The reciprocating grate, made up of four zones, two of them with water
cooling, ensures complete burnout of the waste. The steam generator is
situated above the grate system to recover thermal energy for further
utilization. Downstream of the combustion system is the flue gas treatment
unit, which keeps the plant in compliance with government emission limits at
all times.
Treatment takes place in two stages: destruction of nitrogen oxides by SNCR
(selective no catalytic reduction) followed by semi-dry treatment for safe
removal of gaseous pollutants as well as heavy metals <strong>and</strong> dioxins. Residues
comprise slag for subsequent processing as well as residue from flue gas
treatment for disposal. The 16 MW thermal output of the facility is used in a
cogeneration scheme to produce electric power, which is fed into the local grid
after plant service power is drawn.
What is striking about the Ludwigslust plant is its compact construction. After
passing through the steam generator, the flue gas stream is deflected so that
the flue gas treatment unit can be located next to the process building in order
to save space. The stack is integrated into the building, <strong>and</strong> from outside the
plant it is visible only as a short pipe above the roof.
