循环流化床锅炉飞灰含碳量偏高分析与调整

Analysis and adjustment of circulating liquid bed boiler fly ash carbon content on the high side

循环流化床锅炉(简称CFB锅炉)燃烧采用低温燃烧,是一种清洁燃烧技术,具有良好的脱硫和脱硝性能,同时循环流化床锅炉的飞灰含碳量偏高也是近年来受到关注的问题,在电力生产过程中可以通过燃料管理和运行调整有效降低飞灰含碳量,提高锅炉效率。

Circulating liquid bed boiler combustion adopted low temperature combustion, was a kind of clean combustion technology, had good performance in desuffurization and denitration, while the circulating liquid bed boiler had characteristic on the higher fly ash carbon content, in the process of electric power production can run through the fuel management and this paper indicated that we could effectively reduce the fly ash carbon content through operation adjusting and fuel management, improved the efficiency of the boiler.
