Memory effect on the dioxin emissions from municipal waste incinerator in Taiwan.

摘要: Evaluation of the dioxin removal efficiency air pollution control device (APCD) at an existing municipal waste incinerator (MWI) located in Taiwan is conducted via stack sampling and analysis. The MWI investigated equipped with cyclones, dry lime scrubbing systems fabric filters as APCDs. Results indicate that patterns isomers APCDs' inlet are similar. During first year carbon injection, concentrations emitted decreased greatly. increased from 26.9% to 96.6% after injecting 115 kg/day activated (AC). At second year, reaches 98.7% same rate AC continuously. lower achieved injection (ACI) during can be attributed memory effect, i.e. or precursor desorbs slowly flue gas increases concentration stack, resulting a than expected.
