摘要
论述了精细油水煤浆的制备及其在柴油机上燃用的试验结果,采用生命周期评价方法对精细油水煤浆和柴油的生产及其燃用进行了评价.结果表明,随着精细油水煤浆中柴油含量的减少,除光化臭氧形成潜能降低以外,其它污染指标值都增加,说明精细油水煤浆系统比柴油系统对全球环境冲击更为严重,但在局部地区与燃油相比,燃用精细油水煤浆可以减少NOx的排放量,与燃煤相比,可以减少SO2的排放量.
Described the preparation of ultra-clean micronized coal-water-oil fuel （UCMCWOF） and its usage in diesel engine. The production and usage of UCMCWOF and diesel oil, on a Life Cycle Assessment （LCA） basis, were evaluated. A comparison between the two systems shows that beside reducing of Photochemical Ozone Creation Potential the rest indicators in UCMCWOF increase. This predicates that the system of UCMCWOF is characterized by high global al coal. environmental impact, but its local impacts are lower if compared with the use of diesel and traditional coal.
