Roller Grate / Reciprocating Grate
Ø Both meet all guarantees (burnout incl. siftings)Ø Both have very good referencesØ Both present modern state-of-the-art designØ Roller Grate has lower energy useØ Roller Grate has less maintenance requirementsØ Significant grate bar weight differenceØ Roller Grate has a higher CV limit in standard formØ Geometry configuration is different (70 % difference
in width has advantages for boiler design)Ø Roller Grate has lower exchange ratesØ Roller Grate applicable for both small and large units

ROWITEC® Fluidized Bed Firing
Ø Improved heat transfer through the use of a sand bed.Ø Rapid, complete combustion in the fluidized bed with
a short retention time.Ø High flexibility with regard to variations in the
composition of the refuse.Ø Ease of control due to staged, targeted combustion air
feeding.Ø Reducing atmosphere in the bed zone, therefore
substantially lower NOx levels in the combustor.Ø Complete combustion: the residual carbon content of
the bed ash and fly ash is usually less than 0,1 wt. %.Ø No moving parts in the hot combustor area.
