Abstract (en)

[origin: WO9323147A1] The present invention relates to a process for the admixture of and/or for the achievement of and/or the facilitation of the reduction of undesired compounds, such as soot, hydrocarbons and the oxides of nitrogen and, if the fuel contains other substances, such as sulphur and chlorine, and metal compounds such as mercury and arsenic, for bringing about a reduction in emissions of acidifiying oxides of sulphur and hydrogen chloride, as well as mercury and arsenic compounds, etc., for example in an incineration unit (1<n>). In accordance with the invention, this is achieved by a special admixture and mixing process, in which suitable reducing agents for nitrogen compounds and/or for other undesired substances, for example oxides of sulphur, are introduced into the incineration unit in direct association with the combustion zone (4<n>) in conjunction with the supply of gas. This can take place in conjunction with the actual incineration process, or separately from it. The invention also proposes that the utilization of the admixture and mixing process in conjunction with the supply of air (2) or some other suitable gas and/or gas-borne powder or aerosol compound (5) in itself should lead to the formation of low levels of the oxides of nitrogen, but that is does permit the utilization of other processis, either alone or in combination with this process. The invention also relates to an arrangement for the execution of the process.
