全球能源需求和温室气体排放的持续增长要求越来越多地利用可持续能源，如生物质。在现有的生物质燃烧、气化、生化等转化技术中，燃烧是最成熟、应用最广泛的转化技术。在几个欧洲国家，已经示范了几个容量在1000千瓦的生物质燃烧热电联产厂。然而，适合于家庭应用的生物质燃料微型热电联产（1- 10千瓦）尚未商业化或示范。作者开发的微尺度生物质燃烧有机朗肯循环（ORC）热电联产系统主要由生物质锅炉、ORC流体蒸发器、ORC涡轮机、交流发电机、回热器和冷凝器组成。锅炉产生热水，热水经由蒸发器将热量传递到有机工作流体。产生的有机流体蒸汽驱动涡轮机旋转交流发电机，产生电力。离开涡轮机的膨胀的有机流体蒸汽将其部分热量传递到同流换热器，然后通过冷却水冷凝，冷却水可以加热到约40°C，用于家庭洗涤和地板下加热目的。热电联产系统的初步测试已经进行了最初与9千瓦的电锅炉，然后与25千瓦th生物质锅炉。这些初步测试的实验结果进行了分析，并在本文件中。版权所有2010。牛津大学出版社出版。All rights reserved.如需查询，请发送电子邮件至：journals.permissions@ oxfordjournals.org，牛津大学出版社。
The continual increases in global energy demand and greenhouse gas emissions call for more and more utilization of sustainable energy sources such as biomass. Among the existing biomass conversion technologies such as combustion, gasification and biochemical approaches, combustion is the most mature and widely used conversion technology. Several biomass-fired combined heat and power (CHP) plants with capacities in the order of 1000 kW e have been demonstrated in several European countries. However, biomass-fuelled micro-scale CHP (1--10 kW e ) suitable for domestic applications has yet to be commercialized or demonstrated. The micro-scale biomass-fired organic Rankine cycle (ORC) CHP system currently developed by the authors mainly consists of a biomass boiler, an ORC fluid evaporator, an ORC turbine, an alternator, a heat recuperator and a condenser. The boiler produces hot water which transfers heat to the organic working fluid via the evaporator. The generated organic fluid vapour drives a turbine to rotate an alternator, producing power. The expanded organic fluid vapour leaving the turbine transfers some of its heat to the recuperator and then is condensed by cooling water which can be heated to around 40°C for domestic washing and under-floor heating purposes. The preliminary testing of the CHP system has been carried out initially with a 9 kW electric boiler and then with a 25 kW th biomass boiler. The experimental findings of these preliminary tests are analysed and presented in the present paper. Copyright The Author 2010. Published by Oxford University Press. All rights reserved.
