基于烟气治理全过程的煤电行业SO3减排潜力研究
Study on the Potential of SO3 Emission Reduction From Coal Power Industry in China Through the Analysis of Whole Smoke Treatment Process
摘要
Abstract
The formulation of industrial pollution control policies and emission standards requires comprehensive understanding of SO3 emission quantities and reduction potential in coal-fired power generation.This study establishes a calculation model and methodology for SO3 emissions based on the complete process management of coal-fired power plants,considering both generation and removal mechanisms.Through literature review and field measurements of current SO3 emission characteristics,various standard limit scenarios are analyzed to evaluate future emission reduction potential.Results indicate China’s coal-fired power plants produce approximately 636.0 thousand tons of SO3 annually,with total emissions reaching 150.3 thousand tons,demonstrating a 76.37%overall removal efficiency through existing technologies.Implementing a 10 mg/m3 emission limit would enable 12.64%reduction through environmental upgrades in 20%of generating units,while a stricter 5 mg/m3 limit could achieve 34.84%reduction by upgrading 40%of units.These findings provide scientific basis for establishing appropriate SO3 emission limits and environmental regulation in the coal-fired power sector.关键词
