The contrary direction of movement with the movement of mobile grate piece 16 of fire grate segment 31) it exerts a force to preceding fire grate segment 31.
Similarly, third drop wall 29 is formed between burning zone 12 and burning segment 13.The conveying direction of burning zone 12
The end 12c in downstream side is formed as in vertical direction than the end 13b high of the conveying direction upstream side of burning segment 13.
Third drop wall 29 is provided with third sealing device 30C.The structure of third sealing device 30C is filled with the second sealing
It is identical to set 30B.
The spring 35 for constituting sealing device 30 can be adjusted by changing the position of nut 47.In present embodiment
Sealing device 30 in, can be by making nut 47 extend spring 35 close to preceding fire grate segment main body 37.
In addition, the end of the conveyance direction downstream side of the end 12c of the conveyance direction downstream side of burning zone 12 and burning segment 13
Portion 13c is configured at substantially identical position in vertical direction, alternatively, the end 13c of burning segment 13 is configured at than burning zone 12
The position against the top end 12c.The mechanical kiln grate furnace 1 of present embodiment is by the end of the conveyance direction downstream side of burning zone 12
The end 13c of the conveyance direction downstream side of portion 12c and burning segment 13 is set to the example of identical position in vertical direction.
Then, -15 ° (minus 15 degree) are set as to the angle between -25 ° (minus 25 degree) to by the fire grate inclination angle of dryer section 11
The reasons why be illustrated.
The function of dryer section 11 are as follows: make from the flame radiation heat for being located at the top for being incinerated object T and from fire grate
The sensible heat of primary air below piece more efficiency is well dried the moisture being incinerated in object T.
Here, compared with the sensible heat of primary air, it is higher to dry contribution degree from flame radiation heat, it is incinerated
The drying of the upper layer part of object T is easy to promote.
Therefore, by the stirring action generated by fire grate segment, make the lower layer part for being incinerated object T be moved upward and and upper layer
Portion is replaced, and thus improves rate of drying.
However, not also substantially being in dryer section 11 is to burn, and therefore, it is necessary to true even if being stirred movement
Protect the length for being sufficiently carried out moisture evaporation.Length becomes longer, then device is more enlarged, also more spends cost, it requires
Shorten fire grate length as much as possible.
When absolute value at fire grate inclination angle is bigger than the angle of repose for being incinerated object T, it can be collapsed, not will form due to self weight
T layers of object are incinerated, therefore, it is impossible to be configured to stoker fired grate 5.On the other hand, it is incinerated in the absolute value ratio for making fire grate inclination angle
The angle of repose hour of object T moves (as caused by being self-possessed caused by the gravity as being incinerated object T although can be configured to fire grate
It is mobile) it reduces.Moreover, tilting upward in mounting surface, being i.e. inclined in such a way that positive value (positive value) is in fire grate inclination angle
In the case of, gravity is acted on along will be incinerated the direction that object T is pushed back from conveying direction.
When stoker fired grate 5 is to the conveying capacity of object T is incinerated lower than the amount for being incinerated object T launched, become delivery limits,
It can not be handled.
Optimal fire grate inclination angle is different according to the amount for being incinerated object T and the moisture content for being incinerated object T of dispensing.?
This, the amount for being incinerated object T of dispensing is more and moisture content is higher (amount of moisture is more) situation is incinerated object as launching
Load larger situation is illustrated.On the contrary, the situation that the amount for being incinerated object T launched is less and moisture content is lower is to throw
It puts and is incinerated the lesser situation of object load.
Fig. 8 shows following example: using horizontal axis as the fire grate inclination angle of dryer section 11, using the longitudinal axis as dryer section 11 must
Fire grate length is wanted, is successively incinerated the situation of object load minimum to dispensing from launching and being incinerated the situation (1) of object load maximum
(4) until, the relationship at the fire grate inclination angle of dryer section 11 and the necessary fire grate length of dryer section 11 is delineated.
Here, necessary fire grate length is to instigate 95% dry distance of the moisture for being incinerated object T of dispensing.Horizontal axis
" angle of repose " indicates the angle of repose for being incinerated object T.
As illustrated in the graph of figure 8, -30 ° of fire grate inclination angle is the limit that formation is incinerated T layers of object.Make fire grate inclination angle phase
The fire grate inclination angle for forming the limit for this layer slows down, so that necessary fire grate length is reduced therewith, but switchs at fire grate inclination angle
When positive value, necessary fire grate length is progressively longer.This is because mounting surface is upward, defeated when fire grate inclination angle becomes positive value
It send and slows, thicken as a result, being incinerated T layers of object, the drying for being incinerated object T of lower layer part becomes to be not easy to promote.
The load for being incinerated object T for playing dispensing according to the situation (1) of the load maximum for being incinerated object T from dispensing is minimum
The case where (4) though until four kinds of situations it is found that be incinerated object T be what kind of character, amount, can suitably be located
Reason, and can make fire grate length become shortest optimal dryer section 11 fire grate inclination angle for, -15 ° (minus 15 degree) extremely -
Angle between 25 ° (minus 25 degree) is proper range.Also, optimum value is -20 ° (minus 20 degree).
Then, in the case where the fire grate inclination angle of dryer section 11 is set as proper range as described above, it is suitble to general
The fire grate inclination angle of burning zone 12 is set as+5 ° (positive 5 degree) to the reasons why angle between+15 ° (positive 15 degree) and is illustrated.
The function of burning zone 12 are as follows: utilize the temperature for maintaining to be incinerated T layers of object from flame radiation heat, spontaneous combustion heat
Degree, and the generation for carrying out the fuel gas as caused by the thermal decomposition of volatile component promotes, the remaining fixation after thermal decomposition
The burning of carbon.
Here, compared with the time required for the volatilization of volatile combustible gases, the time required for the burning of fixed carbon
Longer, therefore, the time required for burning of the necessary fire grate length of burning zone 12 by fixed carbon determines.
In Fig. 9, in the case where the fire grate inclination angle of dryer section 11 is set as proper range as described above, with horizontal axis
The maximum feelings of object load are incinerated from dispensing using the longitudinal axis as the necessary fire grate length of burning zone for the fire grate inclination angle of burning zone
Condition (1) plays the fire grate inclination angle for successively until launching and being incinerated the situation (4) of object load minimum, delineating burning zone and combustion
Burn the relationship of the necessary fire grate length of section.Here, the necessary fire grate length of burning zone be instigate combustible component 95% volatilize or
The distance of burning.
As shown in figure 9, -30 ° of fire grate inclination angle is the limit that formation is incinerated T layers of object.Make angle relative to this layer formation
The fire grate inclination angle of the limit slows down, so that necessary fire grate length is reduced therewith.It, can be by fire grate inclination angle in view of delivery limits
Proper range be set as chain-dotted line as shown in Figure 9 encirclement range.
In dryer section 11, even if in the case where dispensing is incinerated the biggish situation of object load, since the fire grate of dryer section 11 inclines
Oblique angle is proper range, so dryer section 11 can also promote, the moisture content of rubbish is reduced and volume is reduced.Thus, for example even if
Load is the load for being equivalent to (1) in dryer section 11, and load can also change to be equivalent to the negative of (3), (4) in burning zone 12
Therefore lotus in burning zone 12, can use bigger fire grate inclination angle.That is, since burning zone can be set as towards upper
Side, so can ensure the residence time required for the burning of fixed carbon, and can shorten fire grate length.
In Figure 10, using horizontal axis as the fire grate inclination angle of burning zone 12, using the longitudinal axis as dryer section 11 and burning zone 12 this two
Fire grate length required for person is successively incinerated object to what is launched from the situation (1) of the load maximum for being incinerated object T of dispensing
Until the situation (4) of the load minimum of T, delineate burning zone 12 fire grate inclination angle and dryer section 11 and burning zone 12 this two
The relationship of fire grate length required for person.Here, the fire grate inclination angle of dryer section 11 is -20 ° (minus 20 degree) as optimum value.
As shown in Figure 10, it is known that: consider delivery limits, the proper range at the fire grate inclination angle of burning zone 12 be+8 ° (just
8 degree) to the angle between+12 ° (positive 12 degree).In addition, (negative for -20 ° as optimum value at the fire grate inclination angle of dryer section 11
20 degree) in the case where, the optimum value at the fire grate inclination angle of burning zone 12 is+10 ° (+10 degree).
For dryer section 11 and the necessary fire grate length of burning zone 12, by the way that each fire grate inclination angle is set as appropriate model
It encloses, be especially set to optimum value, so as to be set as shorter fire grate length as much as possible, therefore, even if burning segment 13 is wrapped
Including including, it can also be set as the smaller and inexpensive mechanical kiln grate furnace of size.
By tilting dryer section 11 downward, so that whether which kind of character is incinerated object T, it can be not stagnant
Burning zone 12 is transported to staying, and by tilting burning zone 12 and burning segment 13 upward, thus abundant to object T is incinerated
Ground is burnt and is conveyed, and is easily slid or is tumbled to the downstream of burning zone 12 without making to be incinerated object T.
That is, being in the case where being incinerated object T of shape for being easy the material of sliding or being easy to roll, due in dryer section
11 roll etc. and be early transported to burning zone 12, accordingly, there exist may not proceed sufficiently dry possibility in dryer section 11
Property.However, since burning zone 12 and burning segment 13 tilt upward, so being incinerated object T not after dryer section 11 tumbles
It can further be tumbled in burning zone 12 and burning segment 13, necessarily be always sufficiently dried in burning zone 12, burn.Due to moisture content
It is high be incinerated object T and be not stranded in 11 ground of dryer section dried and conveyed to burning zone 12, therefore, still similarly, burning
Section 12 is inevitable fully to be burned.
No matter being incinerated the character of object T as a result, it can continuously launch and be incinerated object T, and incinerated matter T can be made
Burn completely.
In addition, the end 13c of the conveyance direction downstream side of burning segment 13 is configured at and burning zone 12 in vertical direction
Conveyance direction downstream side the substantially identical position end 12c, or be configured at the position more against the top than the end 12c of burning zone 12
It sets.Even if being incinerated object T as a result, in the case where dryer section 11 tumbles equal, it can also prevent from being incinerated object T and not fire fully
It is just discharged from burning segment 13 in the state of burning.

The power pulled can be acted on to be pulled and somewhat shifted preceding fire grate segment 31 by mobile grate piece 16.Therefore, even if in movement
In the case where producing the sandwiching of rubbish between fire grate segment 16 and preceding fire grate segment 31, can also it act on before making to sandwich the rubbish
The power that fire grate segment 31 returns.
In addition, due to the moving direction of fire grate segment 31 before being limited using supporting part 32, so can be by preceding fire grate segment 31
Movement be suppressed to minimum limit, be able to suppress the decline of leakproofness.
In addition, by using axis-shaped component 38 and being pivotally supported portion 40,42 and being limited to the moving direction of preceding fire grate segment 31 only
