In the technical solution of the 1st aspect, inner cylinder is covered by outer barrel, and the air being sent into from outside is in the week for being formed in inner cylinder The spatial portion circulation enclosed.The temperature of inner cylinder can be reduced as a result,.Therefore, in the case where refractory material is arranged in the inner peripheral surface of inner cylinder Its thickness can be thinned, so the installation weight lightweight of burner can be made.In addition, also can with the thickness of refractory material can be subtracted Thin amount correspondingly minimizes.

In the technical solution of the 2nd aspect, the air that is sprayed from air jet hole or air injection nozzle become along The air stream of the inner peripheral surface of inner cylinder flows in combustion space, so the inner peripheral surface of inner cylinder is cooled down by the air stream.Therefore, with do not have The case where having setting air jet hole or air injection nozzle, is compared, and the temperature of the inner cylinder in combustion space can be reduced.Therefore, Its thickness can be thinned in the case where refractory material is arranged in the inner peripheral surface of inner cylinder, so the installation weight light weight of burner can be made Change.In addition, also can with can by the thickness of refractory material be thinned amount correspondingly minimize.

The 3rd aspect technical solution in, from inflow entrance flow into exhaust in burner combustion in combustion space The burning gases of generation mix, and flow out to outflux with the shortest distance, therefore the exhaust being sent into from outer can be with smaller Resistance passes through combustion space.In addition, the spatial portion that the air being sent into from outside can circulate is formed between inner cylinder and outer barrel, it is interior Cylinder by air cooling, so be vented and burning gases mixed process in, such as even if in combustion space generate by height The temperature that warm portion, low temperature portion generate is uneven, and the refractory material in covering high-temperature portion need not also be arranged.Therefore, it never needs to such It sets out in terms of the refractory material of temperature unevenness countermeasure in mixed process, installation weight light weight can be made.

The 4th aspect technical solution in, from exhaust spray-hole or be vented injection nozzle spray exhaust become along The exhaust stream of the inner peripheral surface of inner cylinder flows in combustion space, so the inner peripheral surface of inner cylinder is further cooled down by the exhaust stream.Cause This can be such that the temperature of the inner cylinder in combustion space further decreases compared with not having the case where such exhaust ejection section.Cause This, its thickness can further be thinned in the case where refractory material is arranged in the inner peripheral surface of inner cylinder, or refractory material can give up It removes, so the further light weight of the installation weight of burner can be made.

In the technical solution of the 5th aspect, the combustion of outer barrel is set in a manner of fuel can be ejected into combustion space Burner is covered around fuel emission direction by cylinder.Therefore, flame is being formed from burner in the combustion space of inner cylinder In the case of by cylinder cover flame formation range, so the direct radiant heat etc. from flame is covered by cylinder.As a result, can So that the radiant heat transfer amount for the inner wall for being directly delivered to inner cylinder from the flame of burner is reduced, can inhibit the temperature rise of inner cylinder.Separately Outside, the exhaust for the outer for flowing to the downstream side of piping via combustion space from the upstream side of piping is circulated in inner cylinder, So cooling down inner cylinder using such exhaust.Consequently, it may not be necessary to be arranged refractory material etc. in inner cylinder, thus with setting refractory material Deng situation compared to can lightweight.In addition, the appearance and size of inner cylinder can be reduced to the amount of thickness of refractory material etc., therefore also can be small Type.

In the technical solution of the 6th aspect, the fuel emission direction relative to burner of cylinder is located at the base of opposite side End is exposed in spatial portion, and clearance portion is formed between base end part and outer barrel.As a result, using spatial portion flow come From the base end part of external air cooling cylinder, therefore the progress of deterioration caused by the heat due to cylinder, embrittlement can be postponed.Separately Outside, so that the base end part of cylinder is physically isolated with outer barrel using clearance portion, therefore the heat from cylinder to outer barrel can be inhibited to transmit.

In the technical solution of the 7th aspect, the top of supply line on the fuel emission direction positioned at burner of cylinder is in general Outside the range for the imaginary path that the upstream side of piping and the downstream side of piping are connected with the shortest distance.As a result, cylinder relative to from The exhaust stream in the upstream side of piping towards downstream side is not easy to become resistance, therefore can inhibit to flow in combustion space, piping The increase of the pressure loss of exhaust.

In the technical solution of the 8th aspect, the top end part on the fuel emission direction positioned at burner of cylinder is to form Mode for the end shape of oblique circular cylinder is open.Such top end part there are the big long scale portion of the axis direction length of barrel and The small short-scale portion of axis direction length.Thus, for example being located at the peripheral wall side of inner cylinder with long scale portion, short-scale portion is located at inner cylinder The mode of central side configures cylinder.It, can be with the barrel of long scale portion side as a result, about the direct radiant heat etc. from flame The axis direction length amount bigger than the axis direction length of the barrel of short-scale portion side correspondingly, make long scale portion side towards inner cylinder The radiant heat transfer amount in peripheral wall direction is reduced.Therefore, the temperature rise of inner cylinder can be inhibited.In addition, by being fired with the flame of burner Fuel burning and the high-temperature combustion gas that generates are in the flowing of short-scale portion side than being released from cylinder with short distance in the flowing of long scale portion side It puts and towards the central side of inner cylinder.Therefore, the burning gases flowed in long scale portion side can be introduced into the central side of inner cylinder.Separately Outside, high-temperature combustion gas is gathered in the peripheral wall side than inner cylinder by central side, so the temperature rise of inner cylinder can be further suppressed.

In the technical solution of the 9th aspect, the fuel emission direction of burner is from the downstream side of piping to the upper of piping Swim side, thus burner relative to the exhaust stream from the upstream side of piping towards downstream side towards reverse configuration.As a result, in this way Radiant heat etc. to compared with the case where identical direction of exhaust stream is advanced, the direction of travel of the burning gases discharged from burner Vertical component and exhaust direction of travel vertical component become it is oppositely opposed, so the convection current caused by hitting can be promoted Mixing can effectively mix burning gases and exhaust.Therefore, the uniformity coefficient of the temperature of exhaust improves, therefore can inhibit row The temperature of gas is uneven, and the spatially-variable needed for mixing is small, therefore can make inner cylinder and then furnace body is compact.

In the technical solution of the 10th aspect, side of the exhaust downstream side to be connected to the downstream side of piping in combustion space Formula is provided with the second inner cylinder, the internal diameter which has the internal diameter for the interconnecting piece being connect than the downstream side with piping small.By This, in exhaust downstream side, the second inner cylinder prevents the downstream side that the Cryogenic air that inner cylinder cools down is flowed into piping, so can inhibit Since such Cryogenic air makes the temperature of the exhaust flowed about in exhaust downstream side reduce.In addition, in the peripheral wall than inner cylinder Side is more gathered in the second inner cylinder by the exhaust of central side flowing, therefore the exhaust that temperature unevenness can be made few is to the downstream of piping It flows out side.

The piping of the exhaust circulation of outer is existing piping, and the configuration change that need not be piped can incite somebody to action The burner is connected to the midway of piping.It can be easily adaptable existing equipment as a result, therefore can easily correspond to and change Make the so-called repacking that old-style equipment changing is the new equipment that could be used that later.

[the 5th embodiment]

Then, another example as the air discharge heating apparatus that the burner of the utility model is suitable for longitudinal type type, It is illustrated based on Figure 26~Figure 33 pairs of the 5th embodiment.The air discharge heating apparatus 50 of 5th embodiment is also implemented with second The air discharge heating apparatus of the air discharge heating apparatus 20 of mode, the air discharge heating apparatus 30 of third embodiment, the 4th embodiment 40 is same, e.g. by being connected to the midway for the piping 100 that the exhaust of diesel engine (outer) is flowed to make Delivery temperature rises to the heating device for the temperature that denitrating catalyst fully activates, and is mounted in the burner peculiar to vessel of ship.

Exhaust of the air discharge heating apparatus 50 with the 4th embodiment in terms of being likewise supplied with multiple burner units 13 ' adds Thermal 40 is identical, but furnace body be longitudinal type cylindrical shape in terms of, these burner units 13 ' be configured at the side on circumference Aspect that face and burner unit 13 ' have the aspect of combustion barrel 80, Air Blast fan is one etc. and the 4th embodiment Air discharge heating apparatus 40 it is different.In addition, pair constituting portion substantially the same with the air discharge heating apparatus 40 of the 4th embodiment Minute mark notes same reference numerals, keeps explanation simple.

As shown in Figure 26~Figure 31, air discharge heating apparatus 50 is mainly by outer barrel 51, inner cylinder 52, multiple burner units The compositions such as the 13 ', first fan 2.

Outer barrel 51 is, for example, the cylinder for forming cylindrical shape with the end, is made of steel plate.That is, for cylindrical shape is formed as Peripheral wall portion 51a, the one end of outer barrel 51 is in such a way that the circular base end part 51b for being formed interior curved flange shape is surrounded Opening, in addition, the another side of outer barrel 51 is also surrounded with the circular top end part 51c for being formed interior curved flange shape Mode be open.That is, the both ends open of outer barrel 51.It is provided on the outside of the axis direction of outer barrel 51 in the base end part 51b of outer barrel 51 The interconnecting piece 51d of cylindrical extension, in addition in top end part, 51c is also equipped with cylindrical on the outside of the axis direction of outer barrel 51 prolong The interconnecting piece 51f stretched.

Interconnecting piece 51d, 51f are configured in a manner of respective cylinder axis L, M (becoming coaxial) Chong Die with the cylinder axis J of outer barrel 51, It is formed with flange part 51e, 51g on respective top.Interconnecting piece 51d, 51f, respective flange part 51e, 51g be set as can with It is set in the shape specification of the piping connection in ship.As a result, for example relative to (coordinate system shown in each figure in above-below direction Z-direction) setting existing piping, do not change the position of the piping, can the midway of the piping link heating exhaust gas dress Set 50 interconnecting piece 51d, 51g.

In this 5th embodiment, exhaust from interconnecting piece 51d is flowed into the inner cylinder 52 in outer barrel 51 and from interconnecting piece 51f Outflow.That is, exhaust is flowed from upper direction (the arrow base portion direction of the Z axis of coordinate system shown in each figure) directed downwardly.Therefore, The interconnecting piece 51d of exhaust-gas upstream side is arranged in a manner of outstanding into the inside of the inner cylinder 52 then illustrated, i.e. combustion space.By This, is configured to not be connected to aftermentioned air flow path Ra in the downstream tube of the piping of exhaust flowing.In contrast, it is vented downstream The cardinal extremity of the interconnecting piece 51f of side is connected to around the opening of top end part 51c of outer barrel 51, and the burning for not protruding into inner cylinder 52 is empty In.

In addition, in the air discharge heating apparatus 50 of this 5th embodiment, as shown in Figure 29 and Figure 31, in exhaust downstream side Interconnecting piece 51f in be provided with swirl vanes portion 70.The swirl vanes portion 70 is by 73 structure of blade part 71 and annular slab (maintaining part) At multiple blades 72 are configured to annular shape by blade part 71, can assign swirling flow to fluid, annular slab (maintaining part) 73 is by leaf Piece portion 71 remains annular shape, and forms spatial portion 75 in inside.Blade 72 is, for example, the tablet of rectangle, with relative to cylinder axis J can maintain the mode of such as 10 degree~20 degree of constant slope to be fixed on annular slab 73.The width of blade 72 is set as in this time Rotation blade part 70 is more than aftermentioned defined clearance portion Sd in the state of being installed on interconnecting piece 51f, but when the width increases institute When more than requirement, then the internal diameter of spatial portion 75 reduces, therefore is increased by the pressure loss of the exhaust in swirl vanes portion 70.Cause This, sets the width of blade 72 in a manner of becoming without departing from the value for allowing maximum value by the pressure loss of the exhaust of spatial portion 75 Degree.

Swirl vanes portion 70 with this configuration, to from combustion space inner cylinder 52 cylinder axis J central parts and cylinder axis J The exhaust flowed around central part circulates in spatial portion 75 not by blade part 71 and is flowed into the downstream tube of piping. In contrast, the exhaust flowed near the peripheral part and peripheral part of the discharge unit 52e of aftermentioned inner cylinder 52 does not pass through Spatial portion 75, and circulate in blade part 71 and be flowed into the downstream tube of piping.In addition, from air flow path Ra via aftermentioned Gap portion Sd is flowed into the air stream in interconnecting piece 51f also not by spatial portion 75, and circulates in blade part 71 and be flowed into piping Downstream tube.

It is flowed as a result, when the exhaust flowed near the peripheral part of discharge unit 52e, peripheral part and via clearance portion Sd When entering to both air streams in interconnecting piece 51f through blade part 71, convolution is assigned to exhaust and air stream using blade 72 Stream.Therefore, such exhaust and air are flowed into downstream tube after being mixed using the convolution of blade part 71, so can inhibit downstream The temperature of exhaust in pipe is uneven.In particular, the discharge unit 52e of inner cylinder 52 be possible to its top peripheral part deteriorated due to heat, It is deformed due to embrittlement, the feelings of flow equilibrium cannot be maintained due to being deformed the top peripheral part of discharge unit 52e Under condition, it will be vented using swirl vanes portion 70 and air mixing can be directed to and the temperature unevenness of exhaust is inhibited to perform to effect.

Inner cylinder 52 is to be accommodated in the inside of outer barrel 51 and in the internal cylinder for forming combustion space.Inner cylinder 52 and outer barrel 51 It is similarly formed as cylindrical shape with the end.The one end of the cylindric peripheral wall portion 52a of inner cylinder 52 is interior curved convex to be formed The mode that the circular base end part 52b of edge shape is surrounded is open, and in addition the another side of inner cylinder 52 is also interior curved to be formed The modes surrounded of circular top end part 52c of flange shape be open.That is, inner cylinder 52 is also both ends open.In inner cylinder 52 Base end part 52b is formed with the through hole 52d of the interconnecting piece 51d inserts of outer barrel 51, and in addition in top end part, 52c is provided with discharge unit 52e, discharge unit 52e are entered to cylindrical extension on the outside of the axis direction of inner cylinder 52 in the interconnecting piece 51f of outer barrel 51.It should Discharge unit 52e is set as the outer diameter of the internal diameter of the interconnecting piece 51f less than outer barrel 51, and is configured in interconnecting piece 51f Clearance portion Sd as defined in being formed between peripheral wall and the periphery wall of discharge unit 52e.

Inner cylinder 52 with this configuration, to be formed with air flow path Ra between outer barrel 51 and inner cylinder 52.This 5th The inner cylinder 52 of embodiment has multiple venthole 52f in peripheral wall portion 52a.As shown in figure 29, in this 5th embodiment, example Such as, multiple venthole 52f to form a line and annularly be formed in peripheral wall portion 52a in the circumferential at equal intervals.In addition, multiple Venthole 52f is set in the top of the combustion barrel 80 than burner unit 13 ' relative to the forming position of the axis direction of combustion barrel 80 End 80b is near exhaust downstream side and top end part 80b.As a result, in inner cylinder 52, i.e., combustion space and air flow path Ra It is connected to by these ventholes 52f.Therefore, shown in thick dashed line as shown in figure 30, the air that is flowed in air flow path Ra A part for stream can be invaded via venthole 52f in combustion space.

It is set in a manner of surrounding around interconnecting piece 51d in the base end part 52b (inner cylinder cardinal extremity plate 55) of such inner cylinder 52 It is equipped with multiple burner units 13 ', multiple air injection nozzle 55c.Inner cylinder cardinal extremity plate 55 is the component of disc-shape, with inner cylinder 52 peripheral wall portion 52a and top end part 52c forms combustion space together.In this 5th embodiment, 55 (base of inner cylinder cardinal extremity plate End 52b) it is integrally formed with peripheral wall portion 52a.Or inner cylinder cardinal extremity plate 55 is constituted seperatedly with peripheral wall portion 52a, it utilizes The fixed structure of illustration omitted is fixed on peripheral wall portion 52a.

Interconnecting piece 51d is penetrated through in inner cylinder cardinal extremity plate 55.Therefore, it is formed with perforation in the central part of inner cylinder cardinal extremity plate 55 Hole 52d, and in a manner of being surrounded around by through hole 52d with inner cylinder cardinal extremity plate 55 to be formed on the circumference of concentric circles Have towards combustion space side multiple air injection nozzle 55c outstanding.In this 5th embodiment, air injection nozzle 55c It is formed in six positions.Six air injection nozzle 55c are equally spaced configured on circumference, to be sprayed by air in same circumference The mode that nozzle 55c is clipped is penetrated to be arranged there are six combustion barrel openings 55a.Combustion barrel 80 is inserted in combustion barrel openings 55a.

That is, as shown in figure 28, on the circumference for surrounding through hole 52d, between 30 degree of the central angle of inner cylinder cardinal extremity plate 55 Every alternately configuration, there are six air injection nozzle 55c and six burner units 13 '.In addition, burner unit 13 ' is configured at The position of defined clearance portion Sb is left from the peripheral wall portion 52a of inner cylinder 52.It can utilize and be sprayed from air injection nozzle 55c as a result, Air stream cool down burner unit 13 ', and can also cool down the peripheral wall portion 52a of inner cylinder 52.

In addition, the quantity of air injection nozzle 55c is an example, in the range of can play the effect of air stream, exhaust stream It suitably sets.In addition, air injection nozzle 55c, burner unit 13 ' need not be arranged respectively at equal intervals.These air spray The inner space of nozzle 55c is connected to air flow path Ra, therefore is flowed into sky from air entry 51i from 2 force feed of the first fan The air of current path Ra is ejected into peripheral wall portion 52a's for example by dotted arrow shown in Figure 30 via air injection nozzle 55c Inner space, i.e. in combustion space.In addition, the venthole 52f via peripheral wall portion 52a is also ejected into combustion space.

Burner unit 13 ' is mainly made of combustor portion 13a, cylinder 13c and plate 13d.Burner unit 13 ' so that The emission direction of combustor portion 13a is projected into combustion space substantially in parallel towards combustion space and with the cylinder axis J of inner cylinder 52 Mode be installed on the burner installing port 51h of base end part 51b.Combustor portion 13a for example has truncated cone shape on top Spray nozzle part, and it is connected with the cartridge 90 of supply fuel.Combustor portion 13a's is covered by the cylinder 13c of tubular radially around. Combustion barrel 80 as cylinder 13c is located at the base end part 80a of the connecting side of cartridge 90 in sky for example formed as cylindrical shape The mode exposed in current path Ra configures.Utilize the air stream that is flowed in air flow path Ra by combustion barrel 80 as a result, Base end part 80a coolings, therefore the thermal conductivity deterioration due to combustion barrel 80, brittle progress can be postponed.

In addition, combustion barrel 80 be located at interconnecting piece 51d (upstream side of piping) with combustion barrel 80 or its top end part 80b and Interconnecting piece 51f (downstream side of piping) is configured in a manner of outside the range for the imaginary path Rv that the shortest distance connects.This be in order to So that combustion barrel 80 or top end part 80b do not become resistance relative to the exhaust flowed in combustion space, inhibit the pressure damage of exhaust The increase of mistake.In addition, think it may be noted that, seem be present in imaginary path Rv two burner lists in Figure 29 Member 13 ' is actually configured at than imaginary path Rv by the arrow tip direction of the Y-axis of the figure coordinate system.

Moreover, the top end part 80b of the combustion barrel 80 on the fuel emission direction of combustor portion 13a of combustion barrel 80 with The mode for being formed as the end shape of oblique circular cylinder is open, i.e., is not rectangular relative to the cylinder axis of combustion barrel 80, such as tilt 45 Degree ground is sideling open.That is, top end part 80b is not formed as circular open, and it is created as elliptical openings.In this 5th implementation In mode, as shown in figure 29, configured in such a way that the opening of the top end part 80b of combustion barrel 80 is towards the directions cylinder axis J of inner cylinder 52 Six burner units 13 '.Cylinder of the small short-scale portion side of the axis direction length of the barrel of combustion barrel 80 towards inner cylinder 52 as a result, The directions axis J, the big long scale portion side of the axis direction length of the barrel of combustion barrel 80 is towards the directions peripheral wall portion 52a of inner cylinder 52. Therefore, for direct radiant heat of the flame from combustor portion 13a etc., make direction using the long scale portion side of combustion barrel 80 The radiant heat transfer amount in the directions peripheral wall portion 52a of inner cylinder 52 is reduced, and can inhibit the temperature rise of inner cylinder 52.

In addition, the high-temperature combustion gas generated by the flame combustion fuel with combustor portion 13a, compared in combustion barrel 80 long scale portion side flowing, more discharges simultaneously direction with short distance when (short-scale portion side) is flowed near short-scale portion from cylinder The central side (thin dotted line arrow in combustion barrel 80 shown in Figure 30) of inner cylinder.It therefore, can will be attached at the center of combustion barrel 80 Closely, the burning gases of long scale portion (long scale portion side) flowing nearby introduce the cylinder axis J (central side) of inner cylinder 52 (shown in Figure 30 Combustion barrel 80 in thin single dotted broken line arrow and thin dash-double-dot arrow).Accordingly, because the burning gases of high temperature can be assembled The sides cylinder axis J are leaned in the sides peripheral wall portion 52a than inner cylinder 52, so the rising of the temperature of inner cylinder 52 can be further suppressed.

In addition, combustion barrel 80 is formed with multiple ventholes 82 in base end part 80a.In the burner unit of the 5th embodiment Also it is configured in 13 ', it can be with the interconnecting piece of the base end part 80a of combustion barrel 80 and the plate 13d of burner unit 13 ', outer barrel 51 The mode that 51d is not directly contacted with, and the side of clearance portion Sc can be formed between base end part 80a and plate 13d, interconnecting piece 51d Burner unit 13 ' is installed on outer barrel 51 by formula.Because clearance portion Sc is narrow, need to flow into combustion barrel 80 And the air capacity of burning is contributed to increase, so being provided with multiple ventholes 82 on combustion barrel 80.

Moreover, in this 5th embodiment, as described above, being flowed into sky from air entry 51i from 2 force feed of the first fan The air of current path Ra is for example also ejected into combustion space (dotted line shown in Figure 30 via the venthole 52f of peripheral wall portion 52a Arrow).More specifically, near the exhaust downstream side of the top end part 80b of combustion barrel 80, sprayed to the directions cylinder axis J of inner cylinder 52 Air stream.Therefore, it can utilize the air stream sprayed from venthole 52f will be from the high-temperature gas that combustion barrel 80 discharges to inner cylinder 52 Cylinder axis J is released in direction.High-temperature combustion gas can be more effectively gathered in the sides axis J as a result, so in capable of further inhibiting The temperature rise of cylinder 52.Therefore, it is not necessary in refractory materials such as the inner wall setting castables of inner cylinder 52, air discharge heating apparatus 50 ( Furnace body) it can lightweight.

The case where first fan 2, the first air entry 4 are with the first embodiment, four embodiments is substantially same Ground is constituted.Accordingly, with respect to these compositions, the content to respectively recording in the first, the 4th embodiment can be quoted substantially.This Outside, the air entry 51i of outer barrel 51 is sent to via the first aspirating air pipe 6 from the air of 2 force feed of the first fan.As a result, by from The air that air entry 51i is flowed into air flow path Ra is contacted with the lateral surface of inner cylinder 52, so as to pass through air cooling inner cylinder 52.In addition, air discharge heating apparatus 50 does not also illustrate, but it is disposed on base framework.

In this way, in the air discharge heating apparatus 50 of this 5th embodiment, it is (each in above-below direction with the cylinder axis J of inner cylinder 52 The Z-direction of coordinate system shown in figure) erect mode constitute furnace body (outer barrel 51 and inner cylinder 52).In addition, by by burner Unit 13 ' is set to the upper end of furnace body, be thus configured to from combustor portion 13a downward (gravity direction) formed flame.By This, with the gas treatment equipment 10 of such as first embodiment, 10A, the air discharge heating apparatus 20 of second embodiment, 20A~ 20E, third embodiment air discharge heating apparatus 30 such furnace body (be laterally the expansion of X/Y plane in the coordinate system shown in each figure Exhibition direction) configuration the case where compare, the transverse width of air discharge heating apparatus 50 can be reduced.That is, furnace body can minimize.

Even thus, for example in as narrow place such as the engine room in ship, floor area boiler room But short transverse also have it is more than needed in the case of, which can be set.In addition, (external from diesel engine Engine) discharge exhaust flowing piping be laid out (configuration) in above-below direction in the case of, can be by the air discharge heating apparatus 40 It is folded in such existing piping midway and delivery temperature is made to rise to the temperature that denitrating catalyst fully activates.That is, can hold Easily reply repacking.In addition, in the air discharge heating apparatus 50, with the miniaturization of furnace body, Air Blast fan also has a just foot It is enough.Therefore, with the gas treatment equipment of first embodiment 10,10A, the air discharge heating apparatus 20 of second embodiment, 20A~ 20E, third embodiment air discharge heating apparatus 30 compare, the quantity of required Air Blast fan reduces one, corresponding to which, Other than the lightweight of furnace body, air discharge heating apparatus 50 can further lightweight.

In addition it is also possible to which the air discharge heating apparatus 50 of this 5th embodiment is horizontal.That is, with the cylinder axis J phases of inner cylinder 52 The mode of substantially parallel (X-axis or Y direction of coordinate system shown in each figure) is become by furnace body for the ground of setting place (outer barrel 51 and inner cylinder 52) is horizontal.It is vented and is flowed along the directions cylinder axis J of furnace body (outer barrel 51 and inner cylinder 52) as a result, therefore with The gas treatment equipment 10 of first embodiment, 10A, the air discharge heating apparatus 20 of second embodiment, 20A~20E, third are real The air discharge heating apparatus 30 for applying mode is compared, and the length (axial length) in the directions cylinder axis J is small.Therefore, even if it is horizontal, required ground is set Face area more equal than the gas treatment equipment 10 of first embodiment can also be reduced.

In addition, when grasping creation of the composition in above-mentioned swirl vanes portion 70 as technological thought, can show as follows. In addition, swirl vanes portion 70 is an example of following " swirl vanes devices ", the inner space of interconnecting piece 51f is following " in outer barrel An example in space ".In addition, annular slab 73 is an example of following " maintaining parts ", discharge unit 52e is following " downstream sides of inner cylinder An example in portion ".Air flow path Ra is an example of following " air passing spaces ".
