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 particle 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 The resulting flue gas is withdrawn via an open space situated above the particle layer and is subjected to a secondary incineration in a secondary reaction zone or secondary incineration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 () is concentrated with oxygen in such a manner that a mean oxygen content ranging from 0-3 vol. % is set in the open space ().
