Method and system for the thermal treatment of dispersible raw material
A method for the thermal treatment of dispersible raw material may involve introducing raw material into a riser tube that is perfused by hot gases and thermally treating the raw material with the hot gases. Furthermore, the method may involve feeding a fuel to the riser tube. The fuel may initially dwell in a fuel-conditioning region on a bearing face, where the fuel comes into contact with a part of the hot gas that is mixed with the raw material. Consequently, the fuel is dried and/or at least partially de-gassed and/or at least partially reacted and subsequently transferred into the riser tube.

A resulting mixture of mineral substance from the fuel and the calcined clay forms a pozzolanic or latent hydraulic cement clinker substitute, in which a fraction of the mineral substance incorporated into the pozzolanic or latent hydraulic cement clinker substitute by the fuel is 1-60% by weight.
A method for operating a gas sampling probe includes removing a gas to be analyzed from a process space in the region of a front end of a gas sampling tube and conducting it through the gas sampling tube as far as a rear end and, in the process, cooling it by passing cooling air between the gas sampling tube and at least one outer casing enclosing the gas sampling tube. The cooling air is fed and discharged at the rear end of the gas sampling tube and the temperature of the gas to be analyzed is higher in the region of the front end of the gas sampling tube than the temperature of the fed cooling air, and the gas sampling probe emits outward, wherein the temperature of the fed cooling air is higher than the temperature of the discharged cooling air.
