Abstract
The present invention relates to a method for conveying combustion residues (6) along a conveying path out of a combustion chamber (1) in a conveying device (2), comprising the following steps: a) conveying the combustion residues (6) out of the combustion chamber (1) by means of a conveying device (2) which has at least one housing (4); b) producing a first pressure level (12) in the housing (4); c) additionally treating the combustion residues (6) in a treatment device (5) arranged in the conveying path; d) producing a second pressure level (13) in the conveying direction (7) of the combustion residues (6) downstream of the treatment device (5) by introducing a fluid (14) in order to form a pressure gradient.

Method for conveying combustion residues along a conveying path out of a combustion chamber in a conveying device, comprising:
- a) conveying the combustion residues out of the combustion chamber by means of a conveying device which has at least one housing;
- b) producing a first pressure level in the housing;
- c) additionally treating the combustion residues in a treatment device arranged in the conveying path;
- d) producing a second pressure level in a conveying direction of the combustion residues downstream of the treatment device by introducing a fluid in order to form a pressure gradient.
Apparatus for conveying combustion residues along a conveying path with a conveying device, which has at least one housing, and with a treatment device which is arranged in the conveying path and is intended for treating the combustion residues, wherein downstream of the treatment device, as seen in a conveying direction of the combustion residues, at least one nozzle means is provided for introducing a fluid into the housing, and the fluid is accelerated as the fluid flows through the nozzle means in order to produce a second pressure level in the conveying direction downstream of the treatment device.
Boiler, comprising:
- a combustion chamber;
- and
- an apparatus to convey combustion residues from a first location adjacent to the combustion chamber to a second location remote from the combustion chamber, the apparatus including:
- a conveying device having a housing which defines a conveying path having a conveying path direction from the first location to the second location, the conveying device being constructed and arranged to convey the combustion residues out of the combustion chamber and along the conveying path,
- a treatment device disposed along the conveying path, the treatment device being constructed and arranged to treat the combustion residues, and
- a nozzle assembly downstream from the treatment device, the nozzle assembly being constructed and arranged to introduce a fluid into the housing, and accelerate the fluid to form a pressure gradient in which pressure drops along the conveying path direction from the first location to the second location.
