Methods for reducing nox emissions
WebBATs for NOx emission reduction are primary measures combined with staged combustion and SNCR or SCR. Emission values in the range of 200 – 500 mg/Nm3(daily emission values) are achievable when using these technologies. For dust and heavy metals, BATs are also combination of primary and secondary measures. Web11 jul. 2024 · U.S. and European emission standards. We consider the direct material and manufacturing costs of major emission reduction technologies and fixed costs related to research and development, tooling, and certification.
