  • Method of treating a gas stream and method of operating an apparatus for producing a three-dimensional work piece
    Patent number: 12296388
    Abstract: In a method of treating a gas stream (32) containing combustible and/or reactive particles (34) at least a part of the particles (34) contained in the gas stream (32) is separated from the gas stream (32) by means of a separation device (36). The particles (34) separated from the gas stream (32) by means of the separation device (36) are supplied to a collecting vessel (40). The supply of particles (34) to the collecting vessel (40) is interrupted. A flame retardant material (57) is supplied to the collecting vessel (40) so as to form a cover layer of flame retardant material (57) on the particles (34) contained in the collecting vessel (40).
    Type: Grant

  • Method and apparatus for treating combustible and/or reactive particles, method of operating a system for producing a three-dimensional work piece and system for producing a three-dimensional work piece
    Publication number: 20240326134
    Abstract: In a method for treating combustible and/or reactive particles (34) which have been separated from a gas stream (32) by means of a separation device (36) an oxidizing agent is supplied to an atmosphere surrounding the particles (34) so as to cause a passivating oxidation of at least a part of the particles (34). A content of the oxidizing agent in the atmosphere surrounding the particles (34) is detected and the supply of the oxidizing agent to the atmosphere surrounding the particles (34) is controlled in dependence on the detected content of the oxidizing agent in the atmosphere surrounding the particles (34).
