2.2 百 叶 窗 式 煤 粉 浓 缩 器 LOUVER-TYPE PULVERIZED

COAL CONCENTRATOR

为了解决锅炉高温腐蚀、低 NOx 排放和保证较低的不投油最低稳燃负荷，本

工程煤粉燃烧器中本厂所供的一次风均采用百叶窗分离水平浓淡燃烧器。它是由一

次风喷口、一次风管、百叶窗式煤粉浓缩器、一次风方圆节等组成。一次风气流的浓

淡分离是靠安装于一次风管中的百叶窗式煤粉浓缩器来实现的。这种燃烧器利用百

叶窗式煤粉浓缩器使流过的煤粉气流在水平方向上形成浓淡两股气流，浓煤粉在向

火侧，淡煤粉在背火侧。浓气流由于煤粉浓度高，着火热大大降低，析出的挥发物

浓度大，因此有利于着火。此外，淡煤粉在背火侧与二次风配合可以在炉膛周围形

成氧化性气氛，可以起到降低 NOx 生成及防止炉膛结焦的作用。

IS WITH HIGH CONCENTRATION OF PULVERIZED COAL, THE

煤粉浓缩器是由浓缩器壳体、浓缩叶片、挡板及中隔板组成。其叶片长度、叶片

倾角、叶片间距、挡板长度、挡板倾角、分体长度均是通过冷态模拟实验确定的。

为了防止煤粉浓缩器的磨损，在煤粉浓缩器的浓缩叶片、挡板以及浓侧壁面上均贴

有耐磨陶瓷贴片。

PRIMARY AIR CONDUITS SHALL BE DESIGNED EXTRACTABLE.

DURING THE REPAIR, THE PRIMARY AIR NOZZLES AND PRIMARY

AIR CONDUITS MAY BE EXTRACTED OUT FROM THE FURNACE

2.7 燃 烧 器 固 定 装 置 FIXATION DEVICES OF

BURNER

燃烧器固定装置用于燃烧器与刚性梁间的连接，固定燃烧设备。使燃烧设备随

水冷壁自由地作三维热膨胀。燃烧器固定装置及燃烧器与水冷壁的连接只能承受燃

烧设备自身及其保温的荷载，原则上不能承受任何其他外来荷载。

THE BURNER FIXATION DEVICES SHALL BE ADOPTED FOR THE

CONNECTION BETWEEN THE BURNERS AND THE BACKSTAYS

AND THE FIXATION OF COMBUSTION EQUIPMENT TO MAKE THE

COMBUSTION EQUIPMENT EXPAND IN THREE DIMENSIONS

FREELY. THE FIXATION DEVICES OF BURNERS AND THE

CONNECTION BETWEEN THE BURNERS AND WATERWALL SHALL

ONLY BEAR THE LOAD OF EQUIPMENT ITSELF AND THE HEAT

PRESERVATION. IN PRINCIPLE, THEY CAN NOT BEAR OTHER

4MS—3SM版本：A

第 25 页 共 41 页

EXTRA LOAD.

燃烧器同水冷壁之间采用高强螺栓联结，这种连接方式既能使燃烧器随水冷壁

一起自由膨胀，又不妨碍燃烧器与水冷壁之间的胀差。具体的连接操作方法详见图

4MS61-0GW（煤粉燃烧器）。

HIGH-STRENGTH BOLT CONNECTION SHALL BE ADOPTED

BETWEEN THE BURNERS AND WATERWALL, WHICH CAN NOT

ONLY MAKE THE BURNERS EXPAND FREELY WITH THE

WATERWALL, BUT ALSO NOT AFFECT THE EXPANSION

DIFFERENCE BETWEEN THE BURNERS AND WATERWALL.

DETAILED CONNECTION METHOD SHALL BE SHOWN IN 4MS61-

0GW (PULVERIZED COAL BURNER).

2.8 大风箱 WIND BOX

在锅炉两侧燃烧器区域对称布置有两个大风箱，每个大风箱供前后两个角的燃

烧器所需的二次风及周界风。由于大风箱对称布置，使得两侧的风道阻力基本相等，

保证两个大风箱分配到的风量基本相等。大风箱设计入口风速较低，故可将其视为

一个静压风箱，风箱内风量的分配取决于燃烧器自身结构特点及其风门的开度，这

样也就可以保证前后两个角的燃烧器在相同的状态下自然得到相同的风量，有利于

保证炉膛内火焰中心不偏斜。大风箱固定在水冷壁上，与风箱内的刚性梁、桁架连

为一体。

TWO BIG BOXES SHALL BE ARRANGED SYMMETRICALLY IN

THE BURNER AREA AT THE TWO SIDES OF BOILER AND EACH BIG

BOX SHALL PROVIDE THE SECONDARY AIR AND

CIRCUMFERENTIAL AIR FOR THE BURNERS IN THE FRONT AND

BACK CORNERS. DUE TO THE SYMMETRY LAYOUT OF BIG BOXES,

THE RESISTANCES IN THE AIR DUCTS AT THE TWO SIDES SHALL

BE BASICALLY EQUAL WHICH GUARANTEES THE AIR FLOWS

DISTRIBUTED TO THE TWO BIG WIND BOXES ARE BASICALLY

EQUAL. THE INLET AIR FLOW OF BIG WIND BOXES SHALL BE

DESIGNED RELATIVE SLOW, SO THE BOXES CAN BE REGARDED

AS THE WIND BOXES WITH STATIC PRESSURE. THE

DISTRIBUTION OF AIR FLOW IN THE WIND BOXES SHALL DEPEND

ON THE STRUCTURE OF BURNERS THEMSELVES AND THE

OPENING DEGREE OF AIR PORTS, THEREFORE, IT ENSURES THAT

THE SAME AIR FLOW CAN BE NATURALLY GOT BY THE TWO

BURNERS IN THE FRONT AND BACK CORNERS UNDER THE SAME

CONDITION WHICH SHALL BENEFIT THAT THE FLAME CENTER IN

THE FURNACE SHALL NOT GO SKEW. THE BIG WIND BOXES

SHALL BE FIXED ON THE WATERWALL AND INTEGRATED WITH

BACKSTAYS AND TRUSSES IN THE WIND BOXES.

THE INSTALLATION SHALL BE CARRIED OUT STRICTLY

ACCORDING TO THE DRAWINGS AND RELEVANT TECHNICAL

DOCUMENTS；

2) 对燃烧器安装结果应进行全面记录并存档备查；

THE INSTALLATION RESULT OF BURNERS SHALL BE FULLY

RECORDED AND FILED FOR EXAMINATION；

3) 燃烧设备安装前应检查水冷壁安装结果，确保水冷壁安装符合图纸要求后，才

能开始安装燃烧设备；

PRIOR TO THE INSTALLATION OF COMBUSTION EQUIPMENT,

INSTALLATION RESULT OF WATERWALL SHALL BE EXAMINED

TO GUARANTEE THAT THE INSTALLATION OF WATERWALL IS

IN ACCORDANCE WITH THE REQUIREMENT OF DRAWINGS.

UNLESS AFTER THAT, THE INSTALLATION OF COMBUSTION

EQUIPMENT CAN BE CARRIED OUT；

4) 安装前应对燃烧器进行全面检查以核实设备是否符合图纸要求，检查中各风门

第 28 页 共 41 页

的开度及开关方向是否与外部指示一致；

PRIOR TO THE INSTALLATION, THE BURNERS SHALL BE

EXAMINED COMPLETELY TO CHECK THAT IF THE PARTS OF

BURNERS ARE IN ACCORDANCE WITH THE REQUIREMENTS OF

DRAWINGS, IF THE BAFFLES OF AIR PORTS ARE FLEXIBLE AND

IF THE OPENING DEGREE AND SWITCH DIRECTIONS OF AIR

PORTS CONFORM TO THE OUTER INDICATION；

5) 安装时应仔细考虑起吊方式和吊装顺序，采取必要措施严禁吊装过程中燃烧器

产生永久变形；

WHEN INSTALLATION, HOISTING METHOD AND SEQUENCE

SHALL BE CONSIDERED CAREFULLY. NECESSARY MEASURES

SHALL BE TAKEN TO PREVENT THE OCCURRENCE OF

PERMANENT DEFORMATION OF BURNERS DURING

HOISTING；

6) 燃烧器吊装就位后，须检查每个喷口的摆动角度是否与外部指示角度一致，具

体的检查及调整方法（参见附图 6，7）如下：

AFTER THE BURNER IS INSTALLED, IT MUST BE CHECK THE

SWING ANGLE OF EVERY NOZZLE TO ACCORD WITH EXTERIOR

SHOWN ANGLE, THE DETAILED BACK-CHECK AND ADJUST

METHOD SHALL BE AS FOLLOWS:

a. 检查摆杆位置是否正确，使指针（序号 19）必须对准零位；如发现有误，

可调整调节螺母（序号 4）和外连杆（序号 5），使摆杆的指针对准零位；

CWPC—设．004

4MS—3SM版本：A

第 29 页 共 41 页

CHECK THE POSITION OF ROCKER IS RIGHT, THE

INDEX （ NO.19 ） IS POINT TO THE POSITION OF ZERO. IF

THERE HAVE ERROR,IT CAN ADJUST THE CONTROL

NUT（NO.4）AND EXTERIOR ROD（NO.5）.

b. 拆下燃烧器风室的侧盖板，调节各拉杆（序号 7）上的调节螺母（序号

7) 在进行喷口摆动用气动执行器调试时，应保证该执行器带动的各层喷口之间同

步摆动。此外，应保证同组四角的 4只执行器同步动作，以使四角的所有燃烧

器喷口同步摆动（即各喷口摆动一致）；

WHEN DEBUGING THE PNEUMATIC ACTUATORS,THE

NOZZLE OF EVERY FLOOR SHOUD BE SWINGED SYNCHRO.

MOREOVER, TO ENSURE 4 ACTUATORS AT THE SAME GROUP

SHALL BE CONTROLLED SYNCHRO,THAT ALL NOZZLE OF

10) 由于煤粉燃烧器及其相关设备（油枪及推进器、喷口执行器、风门执行器）随水

冷壁作三维热膨胀，因此各类管道、电缆等与上述设备连接时应采用柔性连接

并保证具有足够的位移量。
