Abstract: PROBLEM TO BE SOLVED: To eliminate the loss of powder, to shorten the operation time of a plant and to eliminate risk to the quality of a product by introducing a reaction mixture into a flowing-through pipe, further treating the powder in the pipe and feeding it to a washer, separator or filter. SOLUTION: A dispersion, suspension or emulsion, secondary gas, combustion air and fuel are introduced into a burner 1. The resultant reaction mixture is introduced into a flowing-through pipe 2. An atmosphere of a reducing or oxidizing gas may be established in the flowing-through pipe 2. After passing through the pipe 2, the powder is treated in a washer 3 so as to prepare a dispersion or to prevent contact with air. The powder that leaves the pipe 2 may be separated by a separator 4 for simple treatment at a high temp. or may be separated using a filter 5 for long treatment at a high temp. Waste gas is discharged by a fan 6.

Abstract: A suspension, dispersion or emulsion is introduced into a burner. An optionally two-stage after-treatment is then carried out. The resulting powder can be employed as a catalyst.

Abstract: A powdered heterogeneous substance is produced by treating a dispersion, suspension or emulsion in a turbulent or laminar burner under specified conditions, feeding the reaction mixture into a tube where it is further treated and then feeding it to a scrubber, separator or filter for further treatment.
