NOxpelkistysjärjestelmä
NOxpelkistysjä is a Finnish term that translates to "de-NOxification" or "reduction of NOx." It refers to processes and technologies designed to lower the emission of nitrogen oxides (NOx) into the atmosphere. NOx are a group of gases, primarily nitric oxide (NO) and nitrogen dioxide (NO2), that are formed during high-temperature combustion processes.
These emissions are a significant environmental concern because they contribute to several problems. NOx are precursors
NOxpelkistysjä encompasses both primary and secondary measures. Primary measures aim to reduce NOx formation during combustion
The most common technologies for secondary de-NOxification are Selective Catalytic Reduction (SCR) and Selective Non-Catalytic Reduction
