Ammonia Emission Characteristics and Emission Factor of Municipal Solid Waste Incineration Plant

Abstract

This study aims to analyze whether ammonia emission occurs when municipal solid waste (MSW) is incinerated. In cases where ammonia is emitted, we aim to develop an emission factor, calculate annual emission amounts by utilizing activity data (waste incineration amount) applied in air pollutant emission calculations for the waste combustion in Korea, and investigate whether there is a need for emission calculation. As a result of the study, the ammonia emission factor of the MSW incineration facility to be studied was 0.0091 kgNH3/ton, which was 3 times higher than the emission factor in Europe. In the case of emissions, a randomly developed emission factor was applied to confirm the necessity of development of the emission factor, and as a result of the application, it was found to be 22 NH3 ton/year, which is the same number as the annual NH3 emission of the entire waste treatment sector in 2016. Therefore, we believe that MSW incinerator facilities should be recognized as one of the major NH3 omitted emission sources. Moreover, it is evident that there is a need for an NH3 emission factor and emission calculations that reflect the characteristics of Korea.

Development of Gaseous Pollutant Emission Factor by Incineration of Barley & Wheat among Agricultural Residues

“…영농부산물 소각에 의해 발생한 대기오염물질 발생은 노지 에서 별도의 처리 없이 배출되기 때문에 배출량을 관리하기 힘들 뿐 아니라, 직접적으로 주변 지역에 많은 영향을 끼치며, NO X , SO X 와 같은 가스상 대기오염물질은 초미세먼지 생성에 관여하기 때문에 관리가 필요하다 [5][6][7].…”

Development of Ammonia Emission Factor for Industrial Waste Incineration Facilities Considering Incinerator Type

“…Selective catalytic reduction (SCR) and selective non-catalytic reduction (SNCR) techniques are used to re-move nitrogen oxides, which are air pollutants emitted during incineration processes. If an excess amount of NH 3 is used during the process, it is emitted into the atmosphere [8][9][10][11].…”

Mixed Use of Bio-Oil in Oil Power Plants: Should It Be Considered When Developing NH3 Emission Factors?

“…However, in the case of substances caused by secondary generation, we are only recently paying attention and making efforts to reduce. [4] In South Korea, emissions of NOx and SO X -well-known PM 2.5 secondary sources-have been managed properly based on policies; however, there have not been many studies on ammonia(NH 3 ) [5][6][7][8]. For example, Korea uses NH 3 emission factors from other countries to calculate emissions and has many missing sources for NH 3 .Therefore, the NH 3 inventory needs improvement, including in terms of NH 3 emissions factor development and the estimation of emissions levels reflecting characteristics of South Korea.…”
