高效低污染燃烧及气化技术的最新研究进展

根据参加2003日本神户国际动力工程会议的情况,着重评述了化石燃料低NOX燃烧、固体废弃物焚烧、煤及固体废弃物气化等技术领域的最新研究进展。目前烟气脱硝成为中国电厂技术革新的热点问题,炉内高效低NOX燃烧是一种适于我国国情的高效廉价的技术路线。热解和焚烧相结合的固体废弃物利用技术在日本已得到较为广泛的应用,但是它利用蒸汽轮机发电对于未来小型发电系统而言效率较低,而热解和气化相结合的固体废弃物利用技术是利用内燃机或燃气轮机发电,对于日处理废弃物量小于200t d的发电系统其效率较高,因此成为下一代分布式能源利用系统的良好选择。图7参1

Recent Progress in Research on Efficient Low Polluting Combustion and Gasification Technology

According to proceedings of the International Conference on Power Engineering, held in Kobe, Japan, in 2003, recent technical progress in low NO_x combustion, incineration of solid wastes, gasification of coal and solid wastes are being reviewed in the main. At preset, denitration of flue gas has become an urgent problem in the retrofit of Chinese power plants; highly efficient combustion with low NO_x emission is a cost efficient technology, suitable for Chinese conditions. The technology of waste utilization by combining pyrolysis and incineration has already been popularized in Japan, but its power generation with steam turbines has but an efficiency too low for future small scale power generation systems. Only the technology by means of gas engines or gas turbines proffers a higher efficiency for power generation systems which have a waste handling capacity of below 200t/d, and may thus become a good option for distributed type of energy utilization.
