Research On Air Cooling Dry Bottom Ash Handling Technology Used For The Boiler Of Blomass Power Plant

This paper researches on the bottom ash handling technology of biomass power plant, and has in-depth investigation on the situation and existing problems of current conventional wet bottom ash handling technology for biomass boilers. Making full investigation of the research development of the local and overseas dry bottom ash technology, and learning from the application and operation experience on coal fired boiler dry bottom ash handling technology, and combing the characteristics of biomass power plant, including slight negative pressure operation, regular bottom ash discharge and high carbon content of bottom ash, the paper introduces working principle and technical characteristics of air cooling dry bottom ash handling technology of biomass power plant, and develops a complete and practical technical solution for layout proposal of dry bottom ash handling technology of biomass power plant. The paper also researches and designs on the main equipment of dry bottom ash handling technology of biomass power plant, and has in-depth analysis on the advantages and social benefits from using air cooling dry bottom ash handling technology in biomass power plants, to provide reference and information on environmental protection air cooling dry bottom ash handling technology used for retrofit projects, technical innovation or new built biomass power plants.
