摘　　要：云南华电昆明发电有限公司300MW机组为设计烟煤机组,为降低燃料成本,采取了全烧褐煤的措施,但随着全烧比例的提高,制粉系统故障、空预器堵塞、飞灰含碳量高、燃烧器喷口烧毁等问题严重影响锅炉安全,2018年5月,机组实现全烧褐煤。The 300MW unit of Yunnan Huadian Kunming Power Generation Co.,Ltd.is designed as a bituminous coal unit.In order to reduce the fuel cost,the measures of blending and burning lignite have been taken.However,with the increase of blending and burning ratio,the problems of pulverizing system failure,air preheater blockage,high carbon content of fly ash,burner nozzle burning and so on seriously affect the safety of the boiler.In May 2018,the unit realized the full burning of lignite.This paper describes the full burning of lignite Influence of lignite on boiler and countermeasures.
