- Air atomizing burner
空气雾化喷燃器 - 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。 - These results show that since the existent defects of combustion device structure and its hypothetical circle of contact , these make a poor primary and secondary wind rigidity in operation and a too big actual circle of contact . in addition , the coal used is extreme prone to burn and reside in boiler . under such a condition , the coal powder ignites earlier in a short time and short distance when it leave the jet - combustioning device , and splashes the water cooler , eventually this results in a burned coal residue in boiler
针对宏伟热电厂410t / h燃煤锅炉严重结渣问题,对燃煤的结渣性、炉内温度工况及空气动力工况等进行实验研究,由于燃烧器结构和假想切圆选择的缺陷,使得锅炉在正常运行时,一、二次风刚性较差,实际切圆过大,加上目前燃用煤质属于极易燃、易结渣煤质,致使煤粉在离开喷燃器很短的时间、较短的距离内开始着火,并冲刷水冷壁,最终造成炉膛结渣。
