1. The experimentation of cool and hot diagnosis reflected the structure and disposal of combustor , slag bonding and smirch of hearth are the main factors of hearth ' s outlet overheat and output of boiler decline
   冷、热态诊断试验反映出炉膛结焦、粘污及燃烧器的结构和布置等因素是造成炉膛出口烟温偏高，锅炉出力下降的主要因素。
2. This article aims at the boiler ' s problems in operation : 1 ) under nominal load , the smoke temperature at the outlet of hearth reaches 1200 , far more exceeds 1050 the original designed temperature . this will always result in slag inside boiler and the temperature of overheater ' s pipe superheat , so that boiler cannot take nominal load and all these influence boiler ' s nomal operation heavily , 2 ) this article also studied the reason why the assistant oil becoming necessary when coal changes . during the nomal operation , many factors ( makeup of combustor and its disposal , smirch and encrust of water wall , excessive air coefficient , temperature of primary air , coal type and density of coal dust ) can deviate the designed working conditions , then affect the boiler ' s nomal operation
   本文针对该锅炉在实际运行中存在的问题：在额定负荷下，炉膛出口超温、低温段过热器前烟温高达936 ，远远超过815的设计值；喷燃器四周水冷壁结焦严重，过热器管壁温度超标，无法带上额定负荷；甚至有时因燃煤质量的变化，必须投油助燃的严重情况进行了分析研究。在实际生产过程中，燃烧器的结构、布置，水冷壁的粘污、结垢，过剩空气系数、一次风温、煤种及其浓度变化等许多因素都会偏离锅炉的设计工况，从而影响炉内的传热和燃烧，造成炉膛出口超温、水冷壁结渣等问题。
