Definitions
- the invention relates to a plant for the smoldering of waste and contaminated substances in the absence of air with a smoldering drum and a downstream of the discharge device of the smoldering drum, provided with a combustion device, stair grate, a subsequent afterburning chamber and a waste heat boiler with steam drum.
- Such a smoldering and burning plant is known from DE 37 30 729 C2. It was the object of the cited patent to improve the energy balance in a carbonization system with carbonization drum and device for afterburning the residues from the carbonization drum in such a way that the carbonization gas from the carbonization drum is used to burn the carbon portions of the residue from the carbonization, so that the remaining one solid residues can be stored without problems and the gases can be used as heating gases to heat the smoldering drum and can be used for further heat recovery.
- the carbonization gas from the carbonization drum is used to burn the residues on the stair grate.
- the combustion on the stair grate takes place substoichiometrically.
- the complete smoldering gas combustion takes place above the stair grate and at the entrance to the afterburning chamber.
- the heating gas for the smoldering drum is taken from the waste heat boiler downstream of the afterburning chamber.
- the residue from the smoldering drum is fed uncooled at 400 to 600 ° C onto the inclined step grate.
- several small burners are arranged, which with carbonization gas from the Smoldering drum can be supplied.
- the fuel gas can get into the material to be burned on the grate through the overlapping stair grate steps.
- the combustion takes place with the addition of oxygen.
- the stair grate is cooled by the water-steam mixture from the circulation of the waste heat boiler.
- the object of the invention is to further improve a smoldering plant according to DE 37 30 729 in such a way that complete combustion of the combustible residues from the smoldering drum is achieved and the incombustible materials are obtained as unwashable slag which corresponds to the regulations of the TA municipal waste.
- the solution to these problems is that a ceramic-lined melting chamber is arranged between the stair grate and the afterburning chamber of the known system. Before the discharge material from the stair grate reaches the melting chamber, it is finely crushed with the help of a crusher. The crushing device is therefore installed directly below the stair grate.
- the smelting chamber is fed via a line of carbonization gas from the carbonization drum at a temperature of over 450 ° C, further optionally atmospheric air or pure oxygen. External energy is optionally supplied to heat the air or oxygen to the melting temperature.
- the gases from the melting chamber reach a temperature of more than 1300 ° C in a known manner in an afterburning chamber and then in a waste heat boiler with a steam drum.
- the incombustible residues fall out of the melting chamber into a wet slag remover arranged below them and are discharged as unwashable slag.
- Residues from the smoldering drum (1) are placed in a step grate (3) arranged below and inside a housing (2).
- this stair grate (3) can consist of several inclined individual grids arranged one above the other. The details of the stair grate and the burners have not been shown because they are state of the art.
- the residue emerging from the housing (2) enters the melting chamber (5), which is supplied with atmospheric air (L) or oxygen (O2). If necessary, external energy (F) can also be fed into the melting chamber to heat the air or oxygen to the melting temperature.
- L atmospheric air
- O2 oxygen
- F external energy
- the melting chamber (5) there is a wet deslagger (6) in which the non-combustible residues emerging from the melting chamber are produced as elutable slag
- the melting chamber (5) is followed by an afterburner chamber (7) and then a waste heat boiler (8) with a steam drum (9) is arranged.
- a part of the gases is removed from the waste heat boiler (8) and fed to the smoldering drum (1) as heating gas via line (10).
- the remaining gases pass through line (11) into a gas cleaning system (not shown) Via the line (12) carbonization gas from the carbonization drum (1) reaches the melting chamber (5).
- Part of this carbonization gas (not shown) is fed to the burners of the stair grate (3).
