生物质颗粒燃料取暖的环境健康效益及经济成本分析
Environmental Health Benefits and Cost Analysis of Using Biomass Pellets for Space Heating
摘要
Abstract
Clean heating is a crucial pathway for addressing air pollution and enhancing residents'quality of life.It directly affects people's lives and is a significant measure for combating climate change and achieving development goals.Considering the differences in regional resource endowments and socioeconomic conditions,implementing tailored clean heating policies that leverage the carbon-neutral advantage of biomass resources holds promise for a synergistic reduction in carbon emissions and pollution in suitable areas.However,the empirical evidence on this issue is limited.In this study,on-site monitoring and questionnaire surveys were conducted to quantify the environmental and economic benefits of clean biomass heating.The study found that in rural areas,where biomass pellet heating transformations were implemented,there were significant increases in the efficiency of heating energy utilization,leading to a comfortable warm indoor environment.The median indoor PM2.5 pollution level was 74 μg∙m-3,which was 25%lower than the pre-transformation levels,resulting from reduced indoor emissions.Despite the lower heating values in biomass pellets compared to raw coals,which would cause a slight increase in the consumption of heating fuels,owing to significantly lower PM2.5 emission factors and higher heating transfer efficiency,there was a 54%reduction in the primary PM2.5 emissions after the intervention.In addition to PM2.5,CO2 and other pollutant emissions have decreased by 3%-37%.According to the simulation results,the change can reduce approximately 3 kg of primary PM2.5 emissions and 37 kg of CO2 emissions per household annually,effectively supporting clean heating policies and pollution reduction strategies.Economically,heating costs for post-transformation households did not increase.Compared with the"coal-to-electricity"or"coal-to-gas"options,biomass pellets for heating in the study area presented higher feasibility with lower burdens on both the government and rural residents.Ultimately,the promotion of clean biomass heating that effectively utilizes local resources leads to significant environmental advantages and climate benefits while also demonstrating greater economic feasibility.关键词
