Claims

1. Incineration plant (7 ) having

a combustion chamber (8) ,

a combustion material inlet (9) through which solid material can be introduced into the combustion chamber (8) ,

a combustion grate ( 10) with which the solid material and combusted solid material can be conveyed through the combustion chamber (8 ),

a primary air supply below the top of the combustion grate ( 10), at least one nozzle ( 1 ) arranged above the combustion grate ( 10) with which secondary air and/or an oxygen poor carrier gas can be provided, the nozzle ( 1 ) having a gas inlet (2) and a gas outlet (3) ,

characterized in that

a helically shaped guiding element (4) is arranged in the nozzle between the gas inlet (2) and the gas outlet (3) for impinging a swirl to the gas, the helically shaped guiding element (4) having a front edge (5) and a back edge (6) , wherein the front edge (5) and the back edge (6) are displaced with a distance to each other in a longitudinal direction of the nozzle ( 1 ) .

2. Reactor (11) for cleaning flue gases by a dry or quasi-dry sorption process, comprising

a flue gas inlet (12) at the bottom of the reactor (11), an outlet (13) at the top of the reactor (11),

a dry sorbent injection system (14) with at least one dry sorbent nozzle (1) for injecting dry sorbent with a carrier gas into the reactor (11), the at least one nozzle (1) being arranged between the flue gas inlet (12) and the outlet (13),

the at least one nozzle (1) having a gas inlet (2) and a gas outlet (3),

characterized in that

a helically shaped guiding element (4) is arranged in the nozzle between the gas inlet (2) and the gas outlet (3) for impinging a swirl to the dry sorbent comprising carrying gas, the helically shaped guiding element (4) having a front edge (5) and a back edge (6), wherein the front edge (5) and the back edge (6) are displaced with a distance to each other in a longitudinal direction of the nozzle (1).

3. Incineration plant (7) according to claim 1 or reactor (11) according to claim 2, characterized in that the helically shaped guiding element (4) is flexible and in that the nozzle (1) has a setting element embodied to alter the distance between the front edge (5) and the back edge (6) of the helically shaped guiding element (4).

4. Incineration plant (7) or reactor (11) according to one of the

respective preceding claims, wherein the helically shaped guiding element (4) is made of an elastic material or of an elastically deformable sheet.

5. Incineration plant (7) or reactor (11) according to claim 3 or 4,

wherein the front or back of the helically shaped guiding element (4) is stationary fixed and the back or the front is fixed to the setting element which can be displaced in the longitudinal direction.

6. Incineration plant (7) or reactor ( 1 1 ) according to claim 3 to 5 , wherein the setting element is to be actuated manually or by an electronically controllable actuator.

7. Incineration plant (7) or reactor ( 1 1 ) according to one of the preceding claims, wherein the nozzle ( 1 ) has a central flow channel and an outer flow channel surrounding the central flow channel, wherein a helically shaped guiding element (4) is arranged in the central flow and/or in the outer flow channel.
