Fig. 3 is the stereogram of a part of boundary block 10 of the coal charging type combustion device of presentation graphs 1.Fig. 4 is the vertical cross section of the boundary block 10 of presentation graphs 3.Fig. 5 is the expression horizontal sectional drawing.As shown in Figure 3, boundary block 10 is made of a plurality of module units 100 of cutting apart along the throughput direction of rubbish W.
As Fig. 3～shown in Figure 5, each module unit 100 has: as 2 side plates 11 of the sidewall relative with the end face of the grate 4,5 of coal unit 2; Upper board 12 as the top wall on the top that is configured in side plate 11; And with the pushing portion 13 of side plate 11 to the end face elasticity pushing of the grate 4,5 of coal unit 2.The support beam 15 that stiffener 14 is being fixed in welding is configured in the below of boundary block 10, and boundary block 10 is supported on the support beam 15 via stiffener 14.In addition, support beam 15 is fixed on (with reference to Fig. 2) on the firing machine framework 3.
As shown in Figure 4, side plate 11 has the top protuberance 21 that give prominence to inside side from the upper end, the bottom protuberance 22 that give prominence to inside side from the lower end.Be formed with the groove 23 of the top protuberance 21 of chimeric side plate 11 in the bottom of upper board 12.Because the top protuberance 21 of side plate 11 and the groove 23 of upper board 12 are chimeric like this, so upper board 12 becomes not upward to the structure that breaks away from.In addition, upper board 12 is configured at the length direction (throughput direction of rubbish W) of coal unit 2 with going up free sliding, can absorb the thermal expansion of upper board 12 self.The inspection that boundary block 10 need carry out between short-term is termly reorganized and outfit, but need the time to reorganize and outfit by fixing method inspections such as bolts, therefore in this example, when reorganizing and outfit or checking, by boundary block 10 is slided successively from the upper board 12 of the module unit 100 in downstream, thereby can easily unload these boundary blocks 10.
As shown in Figure 4 and Figure 5, be formed with the slotted hole 31 that extends along the width of stove, in this slotted hole 31, insert to be connected with and implant bolt 32 at the bottom of side plate 11 protuberance 22.As shown in Figure 4, implant bolt 32 and be installed on the stiffener 14 on the support beam 15, thereby side plate 11 is installed on the support beam 15 on this implantation bolt 32 by nut 33 is embedded into.Wherein, nut 33 is consolidated into side plate 11 loosely and can be slided on the width of stove via slotted hole 31.Thus, side plate 11 easily slides on the width of stove corresponding to the thermal expansion of the grate 4,5 of coal unit 2.
As shown in Figure 4, pushing portion 13 comprises: the push plate 41 of end face that side plate 11 is pressed against the grate 4,5 of coal unit 2; As elastomeric helical spring 42 to push plate 41 effects (application of force); Insert the pipe portion 43 of logical helical spring 42; The fixed part 44 of mounting pipe portion 43; And the support plate 45 of supporting the end of helical spring 42.Fixed part 44 is positioned fixing with respect to support beam 15.By such structure, side plate 11 is pressed to the end face of the grate 4,5 of coal unit 2 by elasticity by helical spring 42.
As shown in Figure 5, support plate 45 is adjusted bolt 46 by 2 and is installed on the fixed part 44, adjusts bolt 46 rotations by make these with instruments such as spanners, thereby can adjust the distance between support plate 45 and the fixed part 44.Thus, can adjust the active force of helical spring 42, and adjustable parapleura 11 is with respect to the pushing force of grate 4,5.
By such structure, even when incinerator stops (during cold conditions), on the end face of the grate 4,5 of the side plate 11 of boundary block 10 by being close to coal unit 2 by the helical spring 42 of adjusting bolt 46 compressions.Therefore, in the time of can realizing cold conditions and stove prevent that the bias current that enters, do not have of foreign matter from providing stable combustion air equably, can realize the smooth combustion in the coal charging type combustion device when starting.Can positively absorb the thermal expansion of the grate 4,5 of coal unit 2, therefore can eliminate the restriction of action of the grate 4,5 that the thermal stress of the width that is accompanied by thermal expansion causes or the inordinate wear of grate 4,5 and side plate 11, can carry out stable running for a long time, can prolong the exchange cycle of wearing terrain.
At least be provided with pushing portion 13 more than 1 with respect to 1 side plate 11, add up to the pushing portion more than 2 that is provided with respect to 2 side plates 11 of module unit 100.These pushing portions along the throughput direction of rubbish W by alternate configurations.The fastening amount of the adjustment bolt 46 by adjusting each pushing portion 13 can realize the uniform pushing force to 2 side plates 11.And then pushing portion is provided with number preferably with respect to 2 of 1 side plate 11.As mentioned above, boundary block 10 is made of a plurality of module units 100, therefore will be divided into a plurality of zones (for example arid region, combustion zone, after-combustion zone etc.) in the stove, can adjust the pushing force of each regional side plate 11.Promptly, because the thermal expansion amount difference of each the regional grate 4,5 in stove, therefore by adjust the active force of helical spring 42 with thermal expansion amount of grate 4,5 in each zone, can solve the problem that the part of the caused combustion air of generation in the inordinate wear of side plate 11 and the gap between side plate 11 and the grate 4,5 blows out with offseting.
Wherein, if boundary block 10 does not have the structure that the above-mentioned thermal expansion that absorbs side plate 11 absorbs action, then there is the action of side plate 11 to be limited, produces the possibility of inordinate wear.Therefore, in this example, between the top protuberance 21 of the side plate 11 of boundary block 10 and upper board 12, be formed with the gap 24 of horizontal direction.This gap 24 considers that the thermal expansion uptake of side plate 11 is set, and by gap 24, upper board 12 can not limit side plate 11 thermal expansions and absorb action.
As shown in Figure 4, support that the section shape of the support beam 15 of boundary block 10 is the hollow dihedral, be formed with the stream (air supply stream) 50 that makes the tempering air circulation in the inside of support beam 15.As shown in Figure 5, be formed with a plurality of passages 34 that are connected with the air supply stream 50 of support beam 15 inside in the bottom of boundary block 10.The space that is formed by the side plate 11 and the upper board 12 of boundary block 10 becomes the cooling flowing path 51 of supplying with the tempering air circulation that stream 50 supplies with by passage 34 from air.The size of passage 34 is designed corresponding to the amount of the tempering air of necessity.In addition, in this example, import to cooling flowing path 51 with cooling off the bottom of air, but be not limited thereto, for example also can will cool off air and be directed into cooling flowing path 51 from the top of boundary block 10 from boundary block 10.
Fig. 6 is the ideograph that flows of the cooling air of expression coal charging type combustion device.As shown in Figure 6, coal charging type combustion device has and supplies with extraneous air that stream 50 is connected with the air of above-mentioned support beam 15 inside and supply with stream 52, tempering air is delivered to extraneous air supply with the pressure fan 53 of stream 52, adjust and supply to air and supply with the air quantity of amount of the air of stream 50 and adjust damper (damper) 54, discharge the air of air that circulation is formed at the cooling flowing path 51 of above-mentioned boundary block 10 inside and discharge stream 55 and discharge the extraneous air that stream 55 is connected with air and discharge stream 56.
The cooling air is inhaled into by pressure fan 53, behind air quantity adjustment damper 54 adjustment air quantity, supplies with the air supply stream 50 that stream 52 is fed to support beam 15 inside by extraneous air.This air is supplied with stream 50 interior cooling air are discharged to the inside of boundary block 10 from the passage 34 of each module unit 100 cooling flowing path 51.This cooling air is fed to air when flowing through the helical spring 42 of cooling flowing path 51 cooling boundary blocks 10 inside of boundary block 10 inside or pipe portion 43 etc. and discharges stream 55.Be directed into air that air discharges stream 55 and discharge the suction side that stream 56 is imported into the pressure fan (not having diagram) that combustion air for example uses, be used as combustion air by extraneous air.
As mentioned above, between the top protuberance 21 of the side plate 11 of boundary block 10 and upper board 12, form gap 24 for the thermal expansion that absorbs grate 4,5, but consider that if such gap 24 is arranged then the cooling air in the cooling flowing path 51 drains in the stove, temperature descends in the stove.Also consider and to produce because boundary block 10 is set at rubbish or burns grey contacted position so rubbish or burn ash and invade the inside of boundary block 10, the thermal expansion that hinders side plate 11 and absorb the such significant problem of action, inaccessible passage 34 or cooling flowing path 51.Therefore, in this example, as shown in Figure 4, by the 24 configuration seal members 25 of the gap between the top of side plate 11 protuberance 21 and upper board 12, positively the cooling flowing path 51 of encapsulation boundary piece 10 invades in the boundary block 10 thereby prevent to cool off leakage, rubbish or the burning ash of air in stove.Therefore, Castor Oil ground carries out the action with respect to the thermal expansion of side plate 11, prevents the obturation of passage or cooling flowing path 51 etc., the function that long term maintenance is stable.Can make the cooling air positively the component parts of Contact Boundary piece 10 improve cooling effect, improve the durability of the component parts of boundary block 10.
Wherein, if the cooled air of boundary block 10 directly is provided in the stove, then since in the stove air fed place be limited in boundary block 10 around, therefore can help the quantitative change of burning few as 1 combustion air.Therefore, outside in the excess air cool furnace, also cause increasing the disadvantage of gas flow.Therefore, in this example, the cooling air is discharged the exterior guiding of stream 55 to stove from the cooling flowing path 51 of boundary block 10 by air, make from the inside of boundary block 10 and reduce to the air of stove internal leakage.Thus, can prevent the cooling in the stove due to the excess air or the such disadvantage of increase of gas flow, can not influence the control of combustion air amount, but the stable burning of long term maintenance.
In this example, because stream 50 is supplied with as air in the inside of support beam 15, therefore can apply flexibly the limited space in the coal charging type combustion device effectively, also merge and carry out the cooling of support beam 15.And then, owing to will cool off the cooling flowing path 51 that air supplies to the inside of boundary block 10, therefore can positively cool off helical spring 42 or other component parts in the boundary block 10.In a plurality of zones in the different stove of temperature, set the size (directly) of the passage of boundary block 10 corresponding to this temperature and suitably distribute the cooling air, cool off the helical spring 42 in the boundary block 10 thus effectively, guarantee its function between long-term, improve the durability of the component parts of boundary block 10.
As mentioned above, in this example, by pushing force as elastomeric helical spring 42, the side plate 11 of boundary block 10 is pushed to the end face elasticity of the grate 4,5 of coal unit 2, therefore can improve the sealing between the side plate 11 of the end face of grate 4,5 and boundary block 10, the part that can prevent above-mentioned combustion air blows out or the entering of incombustible etc.Therefore, can carry out the supply of stable combustion air chronically.Can positively absorb the thermal expansion of grate 4,5, reduce the driving resistance that the thermal expansion by grate 4,5 causes.Therefore, can realize that the wearing and tearing of minimizing, grate 4,5 and side plate 11 of load of raising, firing machine framework 3 of mechanical stability of reduction, the grate 4,5 of driving force reduce, can prolong the durable years of coal charging type combustion device extraordinarily.
Owing to the cooling air is circulated in the cooling flowing path 51 of the inside of boundary block 10, therefore can positively cool off boundary block 10.Because therefore the configuration of the gap 24 between the top of side plate 11 protuberance 21 and upper board seal members 25 can prevent to cool off air bleeding in stove, the cooling air can be utilized (recycling) again as 1 time or 2 air.Therefore, compare the control of more stably to burn, avoid the burning of part high load capacity and cross heating, suppress the carrying out of the high temperature corrosion in grate 4,5 and the side plate 11 with coal charging type combustion device in the past.
So far an example of the present invention is illustrated, but the present invention is not limited to above-mentioned example, self-evident, all different forms can be implemented in its technological thought scope.
