随着国内已投运生物质发电厂数量逐渐增多，生物质燃料输送中出现的问题也越来越显著，主要集中在炉前给料系统的蓬料、堵料、结焦等问题上，这些问题导致机组运行不稳定。结合工程实例和生物质燃料特点，给出了4种生物质电厂炉前给料系统方案，并分析了其优缺点，可以为同类型的生物质发电厂的锅炉设计、给料设备选择及机组长期稳定运行提供参考。

More and more biomass power plants have been put into operation recently years in China, with the problems of biomass fuel delivery increasing. These problems are mainly concentrated in boiler-front feeding system, such as fuel shagging, fuel blocking, coking and so on, which may lead to units unstable operation. Base on engineering examples and biomass fuel characteristics, this paper proposed four schemes for boiler-front feeding system in biomass power plant, and analyzed these schemes advantages and disadvantages, in order to provide references for the same type of biomass power plant on boiler design, feed equipment selection and long-term stable operation.
