Abstract: According to a conventional method for incinerating organic waste material, a fluidization device causes an oxygenous fluidizing gas to flow through the waste material, which is located in an incineration chamber, from underneath while forming a fluidized panicle layer and the waste material is incinerated. The resulting flue gas is withdrawn via an open space situated above the particle layer and is subjected to a secondary incineration in a secondary reaction zone or secondary incineration chamber. Expanding upon the prior art, the aim of the invention is enable a high throughput for the incineration material while resulting in a low level of nitrogen oxide production, and to increase the productivity for the incineration of organic waste material. To these ends, the invention provides that the fluidized particle layer (3) is concentrated with oxygen in such a manner that a mean oxygen content ranging from 0-3 vol. % is set in the open space (6).

Abstract: A suppression choke as an overload protection for electric motors according to the prior art is divided in two at a connecting point, which is intended to break in the event of an overload. This produces an additional connecting point by means of soldering. The mechanical stress on the connecting point to be broken often cannot assure a breaking of the connecting point due to the insufficient mechanical initial stress of the windings of the choke.

Abstract: The invention relates to a process for carrying out reactions in fluidized beds with transversal introduction of a reactant selected from oxygen or an oxygen-containing gas and a combustible reactant into a fluidized particle bed by transversal injection at supersonic speed by supersonic nozzles.

Said element is at least partially coated with an elastic material (66) on the side that faces the motor (18), is connected to the receiving housing (12) by its first axial end (54) and lies directly against the motor (18) in the vicinity of its second axial end (58).

Abstract: The starting point is a process to improve the performance of the incineration of combustible waste material in an incineration chamber, whereby the waste material is conveyed to a burner flame where it is burned with combustion air at a temperature in the range from 1100° C. to 1700° C. [2012° F. to 3092° F.]. On this basis, in order to create a process that allows a capacity increase of installations employed for the exothermal incineration of waste materials, it is proposed according to the invention that at least part of the combustion air is replaced by an oxygen-rich gas having an oxygen content that is higher than that of air and that the oxygen-rich gas is mixed with a cooling medium.
