Abstract:
PCT No. PCT/CH96/00006 Sec. 371 Date Oct. 24, 1996 Sec. 102(e) Date Oct. 24, 1996 PCT Filed Jan. 8, 1996 PCT Pub. No. WO96/21825 PCT Pub. Date Jul. 18, 1996Waste is burnt in a furnace chamber (1). The oxygen-containing flue gases resulting in this process are introduced into a fluidized bed in an afterburning chamber (5) and reburnt. Solids discharged with the flue gases from the afterburning chamber (5) are separated from the flue gases in a dust separator (9) and recycled to the afterburning chamber (5), so that a circulating fluidized bed is formed, which produces a very homogeneous temperature distribution in the afterburning chamber (5) and at the same time permits highly efficient cooling of the flue gases. A secondary oxygen feed for the afterburning is dispensed with, which enables a decrease in size both of the afterburning chamber (5) and also of the downstream heat-recovery and gas cleaning devices and improvement in efficiency resulting therefrom.
