Abstract

This study was carried out to collect gas emitted from agricultural heaters using kerosene and to identify the emission concentration of carbon dioxide according to the age of agricultural heating machine. As a result of the linear regression analysis, the carbon dioxide emissions according to the year of agricultural heating machine are R2 = 0.84, which follows y = 26.99x+721.98. Distributed analysis was classified into three groups according to the age of agricultural heating machine. As a result of the distributed analysis, it was 2.196×10-13, which was smaller than the 0.05 probability set for the analysis, which means that there is a difference in at least one group. As a result, the age of the agriculture machine was divided into three groups and the difference between groups was tested. A statistical analysis result was derived that there was a difference in the emission concentration of carbon dioxide according to the age of agricultural heating machine. It is thought that it can be used to investigate greenhouse gas emissions by investigating the amount of carbon dioxide generated by agricultural heaters in the agricultural field of Korea.

본 연구는 등유를 사용하는 농업용 난방기에서 배출되는 가스를 포집하고, 농업용 난방기의 사용 연식에 따른 이산화탄소의 배출농도를 파악하고자 수행되었다. 선형 회귀분석의 결과로 농업용 난방기의 연식에 따른 이산화탄소의 배출량은 R2 = 0.84로 y = 26.99x+721.98의 식을 따른다고 나타났다. 농업용 난방기의 사용 연식에 따라 세 그룹으로 분류하여 분산분석을 수행하였다. 분산분석을 수행한 결과, 분석을 위해 설정한 유의확률0.05보다 작은 2.1961×10-13으로 나타났으며 이는 적어도 한 그룹에서 차이가 나타난다는 것을 의미한다. 본 연구에서는 농업용 난방기의 기본적인 배출농도의 차이를 분석하고자 기기의 제작사와 상관없이 농업용 난방기의 기기 연식만을 고려하여 배출가스 데이터를 수집하였다. 기기의 연소 방식에는 제작사에 따라 연소 방식에 차이가 미미하게 있었을 것으로 판단되며 데이터 변수의 개수가 늘어난다면, SVR(support vector regression) 기반의 선형회귀 분석 등을 실시하여 농업용 난방기의 이산화탄소 데이터가 온실가스발생량 파악에 더욱 활용도가 높아질 것으로 판단된다. 추후 연구에서는 더욱 세분화된 데이터의 수집 방식을 따라 더욱 높은 정확도를 가진 결과값을 도출할 수 있다고 판단된다. 이처럼 우리나라의 농업 분야에서 용도별 온실가스 발생량을 조사하기 위하여 고정형 농기계인 농업용 난방기의 이산화탄소 발생량을 정확히 파악하여 온실가스 배출량 조사에 활용할 수 있을 것으로 판단된다.
