锅炉排出的热渣经进渣管进入滚筒内部，并在进渣管出口周围堆积到一定高度，当灰渣

的重力与进渣管内渣流的重力平衡时，渣流便被阻滞；当由滚筒旋转而带动灰渣向滚筒出渣

端输送时，进渣管出口周围渣堆高度随之下降从而打破了管内外灰渣的重力平衡，管内渣流

又继续。这样，滚筒转，热渣流进；滚筒停，热渣流停；快转快进，慢转慢进。在灰渣输送

过程中，灰渣与冷却水进行热交换，由循环流动的冷却水将灰渣热量带走，灰渣温度降低，

可以由输渣设备运走。

The hot ash discharged from boiler flow into the top end of the barrel through ash down

spout and pile up to a certain height surrounded the ash down spout.When the force of

gravity is balanced with the gravity of the ash flow, the ash flow in the ash down spout will

be prevented; When the barrel rotates and conveys the ash to the outlet end, the height of

the ash pile will discend and break the balance so that the ash flow will continue. In this

case, the hot ash flows into the barrel with its rotating and stop when the barrel stop rotating.

In the process of conveying ash, heat exchange occurrs between the ash and cooling water

and the cooling water reduce the temperature of the ash by taking most of the heat away.

冷渣机运行过程中尤其刚开始运行时，由于锅炉工况不稳定或有结焦情况，有时会出现

热渣在锅炉炉膛正压作用下快速涌至冷渣机出渣口（甚至下一级设备）的现象（通常称这种

现象为“流渣”，非正常情况），该现象没有规律可循，但会有一些预兆：锅炉至冷渣机的进

渣管段整个变红、回水温度迅速升高、冷渣机进出口有大量烟气，热渣会涌到冷渣机出口，

随之锅炉床压急剧下降，出现这种情况应立即停运冷渣机，待回水温度正常后方可再次启动

冷渣机，且低转速启动并视情况确定是否要提高转速。

In the running process of the ash cooler, especially at the beginning of running,

sometimes appear that the hot ash flow directly to the outlet (even the next level equipment)

under the effect of positive pressure (This phenomenon is usually called “scoria flow”)

because the boiler is under an unstable working condition or with coke. There is no

regularation for scoria flow, but has some foretoken: The whole ash inlet pipe turns red and

11

the temperature of return water increases sharply. The ash inlet and outlet are with heavy

smoke and with it the hot ash will flow to the ash outlet. With rapid drop of the boiler

bedding pressure, the ash cooler should be shut down immediately and re-start after the

temperature of return water returns to normal. After restart, the rotating speed should

contron below 30Hz and determine whether to raise the speed as the case.

旋转接头内部的密封填料，需适时调节其压紧度，以维持有少量滴水为宜。填料是易损

件，磨损失效后应及时更换。一般运行 6 个月后应全部更换。

Adjust the tightness of seal stuffing properly in the inner end of the rotary joint and

replace them in time if worn. Generally all should be replaced after working for 6 months.

检查维护与更换旋转水接头里的填料和推力滑轴承时需拆卸其外端盖。推力滑轴承的磨

损程度可从“标杆”端部与水接头轴肩之间的距离显示出来：轴承未磨损时其距离接近零，

随着轴承的磨损其距离变大，当距离增大到 15mm时则需更换推力滑轴承。

应定期检查旋转接头里的轴承。该轴承的磨损程度可从压盖端面与旋转接头轴肩之间的

距离显示出来，随着轴承的损坏其距离变大，当距离增大 15mm时则需更换轴承。

Check the bear of the rotary joint regularly. The abrasion extent of the thrust axletree

can be indicated by the distance between the surveyor’s pole and shaft shoulder of rotary

joint: With the increasing of abrasion on thrust axletree, when the distance extends to

maximum 15mm, the thrust axletree should be replaced then. 冷渣机运行日久其滚筒高度会因支撑圈和支承轮磨损而下降，允许的下降量是 5mm。为

检查滚筒高度，在滚筒的进渣一端下面设有“筒高检测装置”，由上下弧板和接近开关组成。

当其上弧板随滚筒转至最低位时，上下弧板间的缝隙约为 5mm。当滚筒高度因支承轮和支承

圈磨损而下降至上下弧板间隙接近 0.0mm时（接近开关会接通报警），应及时调节滚筒高度至

12

上下弧板间隙约 5～10mm（因外筒外径圆柱度有误差，此间隙需现场调整）。

The barrel may descend because of the adrasion of the support ring and support roller

after long time operation, and the allowable decrease is 5mm.In order to check the height of

the barrel, there is designed a testing equipment of the height of the barrel below the ash

inlet, which is composed of upper arc panel, lower arc panel and proximity switch. When

the upper arc panel goes to the lowest location with the barrel, the gap between the upper

panel and lower panel is 5mm. When the height of barrel decend because of the adrasion

of the support ring and support roller and the gap between the upper panel and lower panel

is close to zero (the proximity switch will alarm), adjust the barrel height in time and make

the gap between the upper and lower panel 5-10mm. (This gap requires field adjustment

because there may be error about the outer diameter of the barrel.)

冷渣机滚筒的轴向位置需保持其支撑圈端面与左右挡轮的间隙大体相等，若偏离较多而

致支撑圈端面贴近其中一挡轮时，则应在运行中调节挡轮以纠正其偏离；冷渣机挡轮处设“轴

向位移检测装置”，当轴向窜动超过设定值时，冷渣机会发出报警信号。

The optimum axial position of the barrel is that the gap between support ring end faces

and two side axial guide rollers are approximately equal. Adjust the axial guide rollers

during operation to optimum position if there is serious deviation between them. “The axial

displacement detecting device” is arranged at the axial guide rollers and the control system

alarm signaled when the axial displacement is out of the limit.

轴向位移过大需重新调整支承轮的位置。

Readjust the support roller’s position if the axial displacementment is too great.

冷渣机进渣密封结构中，密封环、密封圈和进渣管等都是易损件，磨损失常时会造成灰

渣泄漏，则需更换。

更换密封环和密封圈时需先拆下进渣管，更换后需调整滚筒高度，使密封环、密封圈的

间隙保持均匀。

The wearing parts included in the anti-leakage construction such as the ash enclosure,

the ash seal loop and ash inlet pipe shall be repaired or replaced once ash leakage is found

机械设备安装到位后，将电控箱挂置于冷渣机就近的锅炉钢支架立柱上，然后参照滚筒

冷渣机的电气接线图接好线（屏蔽电缆的屏蔽层应接地），电控箱外壳应可靠接地。

After the machine is installed, hang the electric control cabinet on the handy steel pole

of the boiler and connect according to the wiring diagram of the Rotating Ash Cooler (The

shield layer for cable shield should be grounded.). The shell of the cabinet should be

grounded.

3 3 3 3 调调调调试试试试 DDDDebuggingebuggingebuggingebugging

在进行合闸调试前，应先检查一下设备机械安装及电器接线无误。电控箱内电器元件及

螺丝有无松动现象，确认无误后方可送电调试，调试时分就地/远控两种控制方式进行调试。

Before debugging, check whether the machine is installed and connected correctly and

22

whether the electric component and screws in the cabinet loose. Power on for debugging

after confirming above. There are two ways to debug, local and remote.

就地调试方式：Local debugging

调试时，先检查一下冷渣机旋转接头处电接点式压力表的水压是否在设定范围（该设定

范围据现场水循环系统实际值来进行设定）之内，如果水压力低于最小值或者是高于最大值

冷渣机都无法起动，同时操作面板上会有相应的指示灯亮。确定水压力在设定范围内后方可

起动冷渣机进行调试。

Check whether the water pressure at the rotary joint is within the setting limit. (This limit

is set according to the actual value of the water cycle system). If the water pressure is lower

than the minimum or higher than the maximum, the Ash Cooler can not start and the related

indicator will light on the operation board. Please start the ash cooler for debugging after

confirming the water pressure within the setting limit.

调试时先合上电控箱内电源开关 QF，“电源指示”灯亮，同时变频器面板上应有指示，

将就地箱上的“就地/远控”转换开关打在就地上，此时按下电控箱上面板上的冷渣机启动键，

冷渣机应能启动，此时应检查设备转向是否与要求的转向相一致，若不一致可按下冷渣机停

止键使设备停止运行；然后通过变换电机接线加以调整，调整无误后重新按冷渣机起动按钮

使设备起动。起动后按操作面板上的冷渣机升速键相应冷渣机速度应加快，按冷渣机降速键

速度应减慢。通过调整冷渣机升速键及冷渣机降速键，来调整冷渣机速度，使之达到理想的

转速。

Firstly turn on the power switch QF in the electric control cabinet and the indicator

lights. There will be indication on the transducer panel. Please aim the

“Local/Romote”switch at “Local” and press “Start” to start the ash cooler. Check the rotating

direction and correct the direction as requirement.You can adjust the speed of the ash

cooler to achieve the desired rotating speed through pressing“Speed Up”batton and “Speed

Down” batton.

上述调试无误后可进行远控调试（即让冷渣机的转速随着所给 4-20mA 电流信号的变化自

动调整）。

The Romote debugging can be done after the above operation is finished

correctly.( Namely, make the ash cooler adjust the rotating speed Automatically with

changes of 4-20MA current signal.)

23

将电控箱上的“就地/远控”转换开关打在远控上，此时冷渣机应能在远方进行起停并调

速，在远方控制室里按下冷渣机起动按钮冷渣机起动，调节 4—20mA 电流信号的输入，使冷

渣机的转速随着电流信号的变化而变化，同时变频器上又返回一个 4—20mA 的电流信号给集

控室以检测远方冷渣机的运行速度。此时要停冷渣机只需按下冷渣机停止按钮。

Aim the “Local/Romote”switch at “Remote” and the ash cooler will start, stop and adjust

the rotating speed in the distance. Press the batton of “Start” to start the ash cooler and

adjust the input of 4-20MA current signal to make the rotating speed vary with the current

signals. At the same time the transducer will return the last 4-20MA current signal to the

centre control room to test the speed of the ash cooler. You can press the “Stop” batton to

turn off the ash cooler if you want.

水超温报警、断水、水超压、筒体位移超限等是为冷渣机的安全运行而设置的保护功能。

水温检测是通过装在冷渣机冷却水出口的热电阻检测冷却水出口温度，当水温超过设定温

度时（一般设为 95℃）系统发出报警信号提醒用户对设备进行检查，以免发生意外事故，当

水温下降到设定温度以下时报警信号将自动消除。

Water overtemperature alarm, water break, water overpressure, barrel displacement

overlimit are the protection function designed for the safe running of the ash cooler. Water

temperature is tested by the hot resistance equiped on the outlet of the cooling water. When

the water temperature is higher than the setting temperature (95℃ generally), the system

will alarm and remind the user to check the equipment in case of accident. The alarm will

disappear automatically with the water temperature drops to below the setting temperature.

断水、超压是通过装在冷却水出口处的电接点式压力表进行检测的，当断水或水超压时，

冷渣机会自动停车并发出报警信号，这就需要用户检查水路，将水压进行调整，以确保冷渣

机正常运转。

筒体位移、筒体下落检测是为防止冷渣机筒体在不正常的状态下运转。

Water break, overpressure are tested by the pressure gage equiped on the outlet of the

cooling water. The ash cooler will stop automatically and alarm signaled with water break or

overpressure, which need the user to check and adjust the water pressure to make sure the

ash cooler runs normally.

Barrel displacement and discent are tested to prevent the barrel from running under

abnormal condition.
