摘　　要：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。Fossil fuel is the main energy source in China, but it also brings serious air pollution problems. Biomass energy is the clean renewable energy and is one of the important research areas in energy sources nowadays, Therefore it is necessary to develop and apply renewable energy, and adjust and optimize the energy structure step by step. The principle and application status of biomass reburning technologies are introduced. The technologies include direct reburning, reburning with gasification gas and advanced reburning technology. Biomass resources can be utilized properly by using biomass reburning technology. NOx emission amount of coal-fired boilers can also be reduced 50 % 90 %.
