摘　　要：超细煤粉再燃降低氮氧化物排放技术具有较强的经济性和实用性,而超细煤粉的制备是这项技术实施的关键。采用离心式旋转煤粉浓缩器对三次风中的超细煤粉进行浓缩,弱化了三次风对机组运行的不良影响,同时解决了超细煤粉的来源问题,为再燃技术的实施奠定了基础。Micro-pulverized coal reburning is a new technique to deduce NO_x emission, which has been utilized broadly. Micro-pulverized coal's collection is the key during the application.Using rotary-classifier,we collect micro-pulverized coal in the tertiary air to gain the reburning fuel and diminish the influence of the tertiary air on power plant operation at the same time.

关 键 词：再燃 三次风 离心分离浓缩
