我国能源结构以化石燃料为主,不可再生且污染严重,开发和推广应用可再生能源,逐步调整与优化能源结构,意义重大。生物质能是一种清洁可再生能源,也是当前世界能源研究热点之一。重点介绍了生物质再燃利用技术的原理和应用现状,生物质再燃技术包括直接再燃、气化再燃以及高级再燃,使用生物质用于燃煤锅炉再燃,既可以合理利用生物质,又能有效降低燃煤锅炉的NOx排放,NOx减排率可达50%~90%,具有广阔的推广和应用前景。
China’s energy structure mainly fossil fuels, non-renewable and serious pollution, the development and promotion of renewable energy applications, and gradually adjust and optimize the energy structure, of great significance. Biomass energy is a clean renewable energy and one of the hot topics in energy research in the world at present. The principle and application status of biomass reburning and utilizing technology are introduced emphatically. Biomass reburning technology includes direct reburning, gasification and reburning, and advanced reburning. The use of biomass for coal-fired boiler reburning can not only make rational use of biomass but also effectively reduce NOx emissions from coal-fired boilers, NOx emission reduction rate of up to 50% to 90%, with a broad promotion and application prospects.
