Why dry yourcompressed air?Compressed air contains oil, solid particles and water vapors. It is theinherent result of the compression process, which concentrates thenatural water vapors and particles in the air that surrounds us. Thisuntreated compressed air poses a substantial risk to your air system andend products. Its moisture content alone can cause corrosion in pipework, premature failure of pneumatic equipment, product spoilageand more. An air dryer is therefore essential to protect your systemsand processes.Refrigerant dryersby Atlas CopcoAtlas Copco’s refrigerant dryers provide the clean, dry air you need+) to expand the life of your equipment and ensure the quality of yourproducts. Our FD and FX dryers are designed in-house and tested usingthe most stringent methods. They meet or exceed the internationalstandards for compressed air purity and are tested according toISO 7183:2007.253614Controls the speed of the compressor to match your air demand and ensure the highest possible energy savings.1Opens the drain only when needed to eliminate unnecessary loss of compressed air during timed draining.4Counter-flow compact brazed plate or aluminum heat exchanger, with air-to-air side for optimum cooling efficiency and the lowest possible pressure drop.2®Touch controllerProvides advanced control and allows for remote monitoring.5Low velocity with high separation efficiency, even in low flow conditions.3Ensures plug-and-play installation.6VSD for superior energy savingsAtlas Copco’s in-house developed VSD technology matches your FD dryer’s power consumption to your production’s actual airflow. While a traditional refrigerant dryer can only be turned on or off, Atlas Copco’s FD VSD mirrors your production’s demand for compressed air as it fluctuates during the day, week or year. This ensures supreme energy savings as well as a stable dew point.Minimal environmental impactFD VSD dryers use the CFC-free R410A refrigerant, which has an ozone depletion potential (ODP) of zero. The refrigerant meets the strict F-Gas regulations and, due to its low powerconsumption, has an an outstanding TEWI (Total Equivalent Warming Impact) performance.Optimum performance and safety in all conditions• Hot gas bypass valve prevents freezing at lower loads.• The extremely reliable R410A rotary compressor provides the best performance with minimum environmental impact.Capillary tubes cope with all conditions – no moving parts for extra reliability.• Condenser with louvered fin technology for improved performance in dusty environments.Advanced remote monitoring and control• High-tech Elektronikon ® Touch controller with warning indications, dryer shutdown and maintenance scheduling. • Standard SMARTLINK remote monitoring to maximize air system performance and energy savings.Robust and compact design• Forklift opening for smooth transport. • Easy front and side panel access.• No bulky thermal mass heat exchanger needed to save on energy.FiltersIf your production requires higher levels of air quality andfiltration, UD + filters can be added on to your FD VSD dryer.Power consumptionVSD dryerFixed speed dryerSupreme energy efficiency• The FD offers a low pressure drop – typically below 0.2 bar/2.9 psi – and minimal energy consumption.• The compact brazed plate or aluminum heat exchanger was designed specifically to provide optimal pre-cooling and the lowest possible pressure drop.• The electronic no-loss condensate drain comes with a level sensor to open the drain only when needed, preventing unnecessary loss of compressed air.Comprehensive control and monitoring options• The Elektronikon ® Alpha controller displays the pressure dew point and relative humidity.• Remote alarm and start/stop control through voltage-free contact.• Additional features such as alarm history and standard remote visualization.Easy installation and long maintenance intervals• Small footprint thanks to an innovative all-in-one design. • Delivered ready for use, minimizing costly production downtime.Low environmental impactFD dryers use CFC-free refrigerants (R134A and R410A) with an ozone depletion potential (ODP) of zero.Counter-flow compact brazed plate or aluminum heatexchanger, with air-to-air side for optimum cooling efficiency and the lowest possible pressure drop.2condensate drainWith level sensor, backup manual drain and drain alarm.4separatorLasts longer thanks to limited vibrations, minimal moving parts, and reduced risk of leakage.1Reduces energy consumption and optimizes the pressure dew point at very low temperatures.5Low velocity with high separation efficiency even in low flow conditions.3Ensures stable pressure dew point and prevents freezing at lower loads.6connectionAllows for plug-and-play installation.8Eliminates the chance of moisture entering the compressed air system.7Reliable performance in tough conditions• Hot gas bypass valve prevents freezing at lower loads.• R134A piston compressor with high coefficient of performance (extremely reliableR410A rotary compressor for models FD 60-FD 95) provides the best performance with minimum environmental impact.

However, this only represents approximately 10% of the lifecycle cost of the dryer. Energy, maintenance and installation make up the bulk of your actual dryer costs. Direct and indirect (pressure drop) energy costs are the most important.Indirect energy costsIndirect energy costs are related to the extra energy your aircompressor must consume to overcome the pressure drop that takesplace in the air dryer. By design, Atlas Copco FD VSD dryers offer a lowpressure drop and efficient heat transfer – both of which contribute toFD VSD 100-300:Elektronikon ® Touch controller• 4.3-inch high-definition color display with clear pictograms and service indicator.• Internet-based dryer visualization using a simple Ethernet connection.• Automatic restart after voltage failure.• Built-in SMARTLINK online monitoring.• More flexibility: four different week schedules.• Graphical service plan indication.• Remote control and connectivity functions.SMARTLINK & Total ResponsibilityGet the most out of SMARTLINK as part of a Total Responsibility Plan.

But in the end, it’s all about how they perform on your work floor, meeting your individual needs and responding to your specific conditions. That is why the FD VSD, FD and FX come with comprehensive control options to allow you to get the best performance from your Atlas Copco dryer.Remote monitoringHow refrigerant dryers workA refrigerant dryer uses a refrigerant circuit and heat exchanger(s) to pre-coolair, refrigerate it to condense out moisture vapor, and then re-heat the air toAir circuit1Air-to-air heat exchanger: Incoming air is cooled downby the outgoing dry, cold air2Air-to-refrigerant heat exchanger: The air is cooled tothe required dew point by the refrigerant circuit.

能够完成对安装在锅炉本体及空气预热器上的所有吹灰器及吹灰蒸汽管路的控制和监视，可以减轻运行人员劳动强度，更好地保护运行设备，提高锅炉的运行效率。
本说明书适用于重庆白鹤电厂二期1×300MW锅炉吹灰程控系统。
1.1锅炉要求在锅炉的炉膛、过/再热器（水平烟道和尾部烟道）、省煤器和空气预热器上，共布置有湖北戴蒙德机械制造公司制造的121台蒸汽吹灰器。
在本系统中，所有被控对象均有编号。
有关吹灰器的分组及被控对象的编号情况请参考图ZK1532-8。
管路系统简略示意图参见图ZK1532-10。
在正常情况下,当锅炉需要通过吹灰器清洁锅炉受热面上的积灰时,可以使用本控制系统控制吹灰管路阀门和所有吹灰器工作。
根据吹灰器布置的位置，将吹灰器分为左、右侧两大组（或称为单数组、双数组）。
左侧组包括炉膛左、前墙组，过/再热器左墙组，省煤器左墙组和左空预器组；右侧组包括炉膛右、后墙组，过/再热器右墙组，省煤器右墙组和右空预器组。
在正常情况下,整个系统允许处于对应位置的两组中的两只吹灰器同时工作，如布置在炉膛前墙组的IR13吹灰器和布置在炉膛后墙组的IR14同时工作。
锅炉及吹灰系统本身禁止多于2只的吹灰器同时工作，这是因为，吹灰蒸汽管路系统难以提供多只吹灰器同时工作所需蒸汽量，且对锅炉燃烧也可能带来影响。
一般情况下，只有在锅炉负荷较高（建议在70%以上）而炉内燃烧稳定时才进行吹灰，但是否进行吹灰操作要根据实际情况来决定。
当锅炉负荷<10%BMCR时，锅炉本身不能向吹灰蒸汽管路系统提供足够的、适合于吹灰流程需要的主蒸汽而要使用辅助蒸汽，此时只能进行空气预热器的吹灰操作。

蒸汽吹灰器说明书
第一章前言1.1 概述C305-525/C305-545型长伸缩式吹灰器（图1）统称为C305-500系列长伸缩式吹灰器，二种吹灰器的行程范围不同，但其结构形式、传动原理和安装形式基本相同（图2），电气接线和控制原理（图3）也完全相同，零部件大部分通用。
C305-500系列长伸缩式吹灰器是以蒸汽或压缩空气作为吹灰介质，吹扫锅炉受热面上的积灰和结渣的吹灰器。
主要用在清除捕渣管、过热器、再热器和省煤器等部位的结灰，也可用来清除炉顶和管式空气预热器的结灰。
1.2 工作原理(1)清扫原理从伸缩旋转的吹灰枪管端部的两个或几个喷嘴中，喷出蒸汽或压缩空气持续冲击、清洗受热面是本吹灰器的工作原理。
喷嘴的轨迹是一条螺旋线。
吹灰器的运行速度、螺旋线导程（100或150或200mm）和吹灰压力等由吹灰要求决定。
吹灰器退回时，喷嘴吹扫的螺旋轨迹与前进时的轨迹错开1/2节距。
图4为两个喷嘴、100mm导程吹灰器的吹灰轨迹示意图。
(2)主要机构A、高效喷嘴——对每一台吹灰器专门选定。
B、喷嘴传送机构——吹灰枪管、跑车和电动机。
C、向喷嘴提供吹灰介质的机构——阀门、内管、填料压盖和吹灰枪管。
D、支承和包容吹灰器元件的机构——两点支吊的箱式梁。
E、控制系统——提供控制电源和动力电源，控制吹灰器的运行。
(3)吹灰过程吹扫周期从吹灰枪处在起始位置时开始（如图1）。
吹灰器启动后，电动机驱动跑车沿着梁两侧的导轨前移，将吹灰枪匀速旋入锅炉内。
喷嘴进入炉内一定距离后，跑车开启阀门，吹灰开始。
跑车继续前进，吹灰枪不断旋转、前进吹灰；直至达到前端极限后，电动机反转，跑车退回，吹灰枪管以与前进时不同轨迹后退吹灰。
当喷嘴接近炉墙时，阀门关闭，吹灰停止。
跑车继续后退，回到起始位置。

余热锅炉吹灰器使用说明编制：校对：审核：余热锅炉吹灰器使用说明一、概述催化装置余热锅炉配有一套激波吹灰系统，该系统利用乙炔及压缩空气在蓄气罐中按一定配比迅速燃烧产生脉冲激波从而有效清除锅炉受热面的积灰。
吹灰器吹灰系统的布置根据本炉结构、烟气性质，选用我公司的XSJ-JZ型燃气脉冲吹灰系统。
脉冲发生器分别布置在4个吹灰层面，共15个脉冲发生器，15个吹灰点，即：第一层在过热器布置后侧墙3台脉冲发生器，每台脉冲发生器带1只定向喷嘴；第二层在蒸发器前侧墙布置4台脉冲发生器，每台脉冲发生器带1只定向喷嘴；第三层在高温省煤器前侧墙布置4台脉冲发生器，每台脉冲发生器带1只定向喷嘴；第五层在低温省煤器前侧墙布置4台脉冲发生器，每台脉冲发生器带1只定向喷嘴；根据该炉的积灰性质和结构尺寸，在保证吹灰效果的前提下，选择的吹灰点位置和脉冲发生器的尺寸、数量见下表。
系统布置详见施工图纸。

脉冲吹灰器的技术原理：燃气（通常是乙炔或瓦斯）在特殊结构混配点火装置中，与空气混合，被高能点火器点燃，产生爆燃，爆燃气体受罐体内特殊结构的调制瞬间产生冲击波。
当冲击波作用于积灰表面时，其声能和动能将对灰粒子产生冲击和加速扰动，使之与受热表面分离，从而脱落。
通过对两种气体的配比浓度和蓄能量的控制生成不同形式和不同强度的冲击波，可完成不同程度、不同类型积灰的清除。
脉冲激波吹灰系统的主要特点是：冲击波将能量聚积于极短时间和空间，在气体介质中形成瞬间能量间断面，使气流的压力和速度产生突变，其瞬间传播速度为度量尺度，声压可达到160dB以上，压力通常10～15㎏/㎝2，速度可达300～350m/s。
