过剩空气
Examples
- Staff was reminded to switch off lightsair conditioners during lunch or away for long hours and to keep room temperature at a reasonable level to avoid excessive air conditioning
我们提醒所有的工作人员在午膳时或离开办公室一段颇长的时间时，须把冷气机及电灯关掉，同时须把室温保持在一个合理的度数，以免浪费能源。 - Energy conservation staff was reminded to switch off lights air conditioners during lunch or away for long hours and to keep room temperature at a reasonable level to avoid excessive air conditioning
我们提醒所有的工作人员在午膳时或离开办公室一段颇长的时间时，须把冷气机及电灯关掉，同时须把室温保持在一个合理的度数，以免浪费能源。 - This a / f controller could quickly response and regulate the lpg injection time to meet different engine running conditions and make excessive air coefficient ( a ) in normal operation range of the three - way ca alyst system ( twc )
该控制器能根据不同的工况快速反应并调整燃料喷射占空比，使过量空气系数符合三效催化转化器有效工作范围( = 1 0 . 005 ) 。 - 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。
