Furthermore, the free end of the pipe can be nachgeschreibx in a possible burn-off of the tip due to ongoing high thermal stress during operation of the burner unit.

- the inner shaft wall of the main shaft 10 is formed by a lower inner cylinder 30, which is the
- Oberschachtes 20 by an upper inner cylinder 40 by an upper inner cylinder 40.
- a plurality of burner assemblies A of the type described in connection with FIG. 2 are arranged in a lower burner level, of which m is the present sectional view visible.
- the Brennereinhej th the upper burner level can also be formed in the inventive manner.
- the granular material G (limestone) to be fired is placed in the annular shaft kiln and, owing to gravity, first moves through the preheating zone VZ, where it is heated in countercurrent by exhaust gases rising from the combustion zone BZ. As soon as the firing material G has passed the upper inner cylinder 40, it enters the combustion zone BZ and is burned there in countercurrent and below the lower burner level with the burner arrangements A in DC. Subsequently, the now fired Good G * enters the Kuhlzone KZ, where it is again cooled in countercurrent. Finally, the product G * is discharged from the annular shaft furnace.
- m of the preheating zone VZ of the upper shaft 20 flows into an exhaust part ⁇ : rom in the upper inner cylinder 40 and from there into a recuperator unit 70, where it heats a three-air flow path.
- the injection air provided by the injectors 50 often does not have those for the ignition of the
- Another advantage of the presented burner concept is that existing burners can be easily converted in such a way that they also allow the use of an additional fuel such as natural gas.
