福建无烟煤是我国最难燃烧的煤种。挥发分含量最低,约2—4％;析出缓慢,又无集中析出的峰值,燃烧中瞬时浓度极低。长期以来依靠助燃油来维持燃烧,每度电油耗达60克,燃烧仍不稳定,燃烧效率仅73％,飞灰含碳量达45％。燃烧处于极不正常状态。 本文为国家“六五”重点科技攻关项目。由福建省电力中心试验所和厦门电厂的共同协作,研制成功,大大改善了福建无烟煤的燃烧稳定性。并使锅炉效率提高5.8％,助燃油耗下降50％左右。使福建无烟煤的燃烧技术得到了很大发展。
Fujian anthracite is China’s most difficult to burn coal. Volatile content of the lowest, about 2-4%; Precipitation is slow, there is no concentrated precipitation peak, the instantaneous concentration of combustion is very low. It has long relied on fuel oil to maintain combustion, with an electricity consumption of 60 grams per degree. The combustion is still unstable with a combustion efficiency of only 73% and fly ash with a carbon content of 45%. Burning in a very abnormal state. This article is the national “six five” key scientific and technological project. Developed by Fujian Power Center Experimental Station and Xiamen Power Plant, it has been successfully developed and greatly improved the combustion stability of Fujian anthracite. And to improve the efficiency of the boiler 5.8%, helping fuel consumption decreased by about 50%. Fujian’s anthracite combustion technology has been greatly developed.
