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.
