The SNCR-Procedure - A Proven Technology to Substancially Reduce NOx Emissions in Waste Incinerators -

Nitrogen oxides (NOx), one of the main pollutants, are formed in substantial amounts, even under optimised combustion conditions. Due to the reaction of nitrogen oxides with other compounds in the atmosphere ozone is formed and leads to the so called summer smog. Other reaction products, nitric acid, cause acid rain and get into the soil. This leads to the enrichment with nitrates and has a negative impact on humans, vegetation and animals.

For this reason in most of the industrialised countries laws are put in force to limit nitrogen oxide emissions. The emission limits are continuously adjusted to the state of the art and periodically restricted. Regarding the provenience of the NOx emissions across the industrial branches, more than half are produced by the incinerators.

Partly nitrogen oxides are formed at high temperatures due to oxydation of nitrogen from the combustion air - the so called thermical NOx. On the other hand nitrogen oxides are formed by oxydation of the organically bounded nitrogen in the fuel. The nitrogen content in the fuel seriously influences the NOx emission.

Recently NOx is no longer regarded as a single emission but together with other emissions potencially arising from applying further emission reduction procedures, in order to monitore the amount of non desired side emissions such as the so called ammonia slip (NH3) and/or the hilariant gas (N2O) and their consequences, but also to determine the quality of futher applications.

In the context of the European Climate Law (EU) 2021/1119), the Governance Regulation (EU) 2018/1999 and the Nature Restoration Regulation (EU) 2024/1991, the KAnG came into force on July 1, 2024.

Transformatives Klimarecht: Raum, Zeit, Gesellschaft

This article contends that climate law should be conceived as inherently transformative in a double sense. The law not only guides the necessary transformation of economy and society, but is itself undergoing transformation.
