摘要:首先分析了大型硫酸盐木浆厂中石灰窑的温室气体排放特征，阐述其为硫酸盐木浆厂化石燃料最大消耗单元的主要原因，然后重点探讨石灰窑温室气体排放核算的路径，最后进一步提出石灰窑实现碳中和的可能技术途径，包括生物质燃料在石灰窑中的应用、石灰窑和碳捕获与封存（CCS）的集成技术以及石灰窑技术改造等。

Abstract:The greenhouse gas emission characteristics of lime kiln in large-scale kraft wood pulp mills were analyzed， and the main reasons why lime kiln was the largest fossil fuel consuming unit were expounded. Then the pathways of greenhouse gas emission accounting of lime kiln were emphatically discussed. Finally， several possible technical approaches to realize the carbon neutralization in the lime kiln were further proposed， including the use of biomass fuels in lime kiln， integrated technology of lime kiln and carbon capture and storage （CCS）， and technical transformation of lime kiln.
