摘要
英格兰北部城市Barnsley建有大量以生物质为燃料、中小规模的分布式供能系统,在可持续的分布式能源的发展上处于英国的领先地位。本研究对Barnsley两个典型的分布式供热系统的污染物排放进行了试验和数值模拟研究,分析其燃烧特性和整体性能。研究结果表明,以生物质为燃料的分布式供热系统,污染物的排放浓度在排放标准范围之内,而且所产生的污染物(如CO、CO2、NO和颗粒物)的浓度要低于燃煤锅炉。Barnsley成功开发和运行大量独立的"迷你"型分布式供热系统的经验,为我国农村和新型城镇建立和发展可再生新型供能模式提供了一个很好的参考和借鉴。
Barnsley in the north of England leads the UK in terms of sustainable district heating, through the implementation of small -/district - scale biomass heating systems. This paper investigated two bio- mass -fuelled heating systems installed in Barnsley, where pollutant monitoring and numerical simulation were carried out to evaluate combustion characteristics and overall system performance. It is found that the pollutant levels from the biomass combustion system were within the emission limits. The concentra- tions of flue gas （i. e. CO, C02, NO and particulates） from the biomass boiler were lower than the coal boiler. The successful experience in the development and operation of a series of ＇ mini＇ biomass - fu- elled district heating systems in Barnsley will provides a good reference for building and developing a new energy supply pattern in China＇ s rural area and newly developed town centres.
