Each soot blower 22 comprises the long combustion pipe 26 that extends to the proximal downstream end 30 of abuts wall 24 from the upstream far-end 28 away from furnace wall 24.Yet randomly, end 30 can suitably be positioned at stove.When each soot blower of operation, the burning of fuel/oxidant mixture that is positioned at pipeline 26 is in that beginning is so that produce detonation wave near upstream extremity (for example the upstream of duct length 10%), and this detonation wave penetrates so that the surface in the internal volume of stove is cleaned from downstream as shock wave with relative combustion gas.Each soot blower can be associated with fuel/oxidant source 32.This provenance or its one or more parts can be shared by each soot blower.An exemplary source comprises liquefaction or compressed fuel gas cylinder 34 and the oxygen cylinder 36 that is arranged in corresponding container structure 38 and 40.In the exemplary embodiment, oxidant is for example oxygen of substantially pure of first oxidant.Second oxidant can be the form of 42 shop airs of carrying from the center air source.In the exemplary embodiment, air is stored in the air receiver 44.The fuel that is got by the fuel volumetric growth in the cylinder 34 generally is stored in the fuel accumulator 46.Each exemplary source 32 is connected on the associated conduit 26 by the suitable waveguide that is positioned at the below.Similarly, each soot blower comprises spark case 50, and it is used for the fire fuel oxidant mixture, and it is controlled by control and monitoring system (not shown) with source 32.Also illustrate among Fig. 1, wall 24 comprises a plurality of mouths of checking and/or measuring of being used to.Exemplary mouth comprises optical monitoring mouth 54 and the monitoring temperature mouth 56 that is associated with each soot blower 22, is used for putting respectively infrared ray and/or visible light camera and thermocouple probe, so that observe surface to be cleaned and monitoring internal temperature.Also can use other probe/monitoring/sampling apparatus, comprise pressure monitor, composition sampling apparatus, or the like.
Fig. 2 shows the more details of exemplary soot blower 22.Exemplary pinking pipeline 26 has by the pipe sections or the part 60 of the two flanges of a series of bands that are from upstream to arranged downstream and has the downstream nozzle pipe sections of downstream part 64 or the main part that part 62 forms, and downstream part 64 extends through the hole that is arranged in wall and ends at the downstream that is exposed at furnace interior 68 or export 30 places.The term nozzle is the meaning of summarizing this usefulness, thereby does not require contraction, expansion or its combination that exists on any air electrodynamic.Illustrative conduit portion section material is metal (a for example stainless steel).If provide suitable supporting and cooling device, outlet 30 can be positioned at stove position more inward.Fig. 2 also shows tube bank 70 in the stove, and often there is dirt in their outer surface.In the exemplary embodiment, each pipe sections 60 is supported on the relevant chassis 72, and the wheel of chassis 72 engages with rail system 74 along equipment bay 76.Exemplary rail system comprises the closed slide that spill outer surface a pair of and the chassis wheel engages.Each exemplary section 60 has similar length L 1, and the associated bolt array of the bolt hole by being arranged in its respective flange and bolt end-to-end.Similarly, the downstream flange of the downstream portion section in each section 60 is bolted on the upstream flange of nozzle 62.In the exemplary embodiment, the reaction band 80 (for example firm synthetic material on cotton or the calorifics/structure) that is connected in series with one or more metal spiral antagonistic springs 82 is connected in this most last flange that matches to last, and combustion pipe is connected on environmental structure such as the furnace wall, so that flexibly absorb the reaction force relevant and the assurance combustion pipe is correctly placed to light subsequently with the emissions operation of soot blower.Randomly, can provide other damping (not shown).Reaction band/spring assembly can form single length or ring.In the exemplary embodiment, the downstream portion section of this combination has total length L 2Substituting elastic recoil absorption plant can comprise nonmetal or non-helical spring or rubber or other under tension force, compression and/or shear action advantageously to the elastomer element of small part strain, air pressure recoil absorber, or the like.
Pre-detonating agent pipe sections 84 is extended downstream from upstream extremity 28, and it also can be with two flanges and have length L 3The feature internal cross-sectional area (perpendicular to the axis/center line 500 of pipeline) of pre-detonating agent pipe sections 84 is less than the feature internal cross-sectional area of the downstream part (60,62) of combustion pipe (for example average, intermediate value, mode, or the like).In the exemplary embodiment that relates to circular cross section pipeline portion section, pre-detonating agent cross-sectional area is characterised in that diameter between between the 8cm to 12cm, and the downstream part is characterised in that diameter is between between the 20cm to 40cm.Correspondingly, the example transverse cross-sectional ratio of downstream part and pre-detonating agent portion section is between 1: 1 to 10: 1, and is narrower, between 2: 1 to 10: 1.Total length L between the end 28 and 30 can be 1-15m, and is narrower, is 5-15m.In the exemplary embodiment, transition conduit portion section 86 extension between pre-detonating agent portion section 84 and upstream portion section 60.Portion's section 86 has size and is suitable for the upstream and downstream flange that matches with the respective flange of portion section 84 and 60, and has the inner surface that seamlessly transits is provided between the internal cross section of portion's section 84 and 60.Exemplary section 86 has length L 4Exemplary half-angle≤12 of dispersing of the inner surface of portion's section 86 °, narrower, be 5-10 °.
The fuel/oxidant charging can be introduced the pinking pipe interior according to variety of way.One or more different fuel/oxidant mixtures can be arranged.This mixture can carry out premixed in pinking pipeline outside, perhaps can introduce the pipeline place or introduce the laggard row mixing of pipeline.Fig. 3 shows portion's section 84 and 86 and is configured to and is used for introducing respectively two kinds of different fuel/oxidant combinations: pre-detonating agent combination; With main combination.In the exemplary embodiment, in the upstream portion of portion's section 84, a pair of pre-detonating agent fuel injection pipe road 90 is connected on the mouth 92 of the Duan Bizhong of portion that defines fuel injection orifice.Similarly, a pair of pre-detonating agent oxidant conduit 94 is connected on the oxidant inlet 96.In the exemplary embodiment, these mouthfuls are arranged in the upstream half section on the length of portion's section 84.In the exemplary embodiment, each all (is depicted as exemplary 90 ° in that identical axial positions is angled in the fuel injection orifice 92, but also can be for comprising other angle of 180 °) with relevant oxidant mouth 96 pairings so that mix for fuel and oxidant provide relative jet.Will further discuss hereinafter, purge gas pipeline 98 is connected on the purge gas mouth 100 similarly at upstream end more.The end plate 102 that is bolted on the upstream flange of portion's section 84 is sealing the upstream extremity of combustion pipe and is passing the igniter/trigger 106 (for example spark plug) with the operation end 108 that is positioned at portion's section 84 inside.
In the exemplary embodiment, main fuel and oxidant are introduced in portion's section 86.In the embodiment shown, main fuel is transported by a plurality of main fuel pipelines 112 and primary oxidant is transported by a plurality of primary oxidant pipelines 110, wherein each primary oxidant pipeline 110 has with one heart the port around associated fuel pipeline 112, so that at relevant inlet 114 places mixing main fuel and oxidant.In the exemplary embodiment, fuel is hydrocarbon.In special exemplary embodiment, two kinds of fuel are identical, and but they are drawn from single fuels sources mix with different oxidant: mix so that obtain pre-detonating agent mixture with pure basically oxygen; Mix so that obtain main mixture with air.Available in this case exemplary fuel has propane, MAPP gas or its mixture.Also other fuel be can use, ethene and liquid fuel (for example diesel oil, kerosene and jet aviation fuel) comprised.Oxidant can comprise mixture, and the air/oxygen mixture of proper proportion for example is so that obtain required master and/or pre-detonating agent charging chemical property.In addition, have the fuel of molecular combinations and the monopropellant fuel of oxidant constituents and also can be used as selection.
When operation, begin the place in life cycle, except having air (or other purge gas), when beginning, be sky in the combustion pipe.Pre-detonating agent fuel and oxidant are introduced by critical point mutually subsequently, charge into portion's section 84 and extend partially in portion's section 86 (for example near midpoint), and advantageously just surpassed main fuel/oxidant mouth.Cut off pre-detonating agent fuel and oxidant stream then.The pre-detonating agent fuel that charges into and the exemplary volume of oxidant account for the 1-40% of combustion pipe volume, and be narrower, accounts for 1-20%.Introduce main fuel and oxidant then so that charge into the combustion pipe residual volume of definite part (for example 20-100%) basically.Cut off main fuel and oxidant stream then.Introduce pre-detonating agent fuel and oxidant through main fuel/oxidant mouth before this, just eliminated between pre-detonating agent and main charging, forming air or other does not fire the danger of piece greatly.This can prevent that combustion front from moving between two chargings.
After introducing charging, with regard to the pilot spark case so that the spark discharge of trigger is provided, thereby light pre-detonating agent charging.Pre-detonating agent charging is chosen to have the chemical property of very fast burning, and therefore in portion's section 84, initial detonation changes pinking apace into, and produces detonation wave.In case produced this detonation wave, just can pass through main charging effectively, and main charging may have enough slow chemical property in addition so that can pinking in pipeline automatically.Ripple longitudinally passes through downstream and occurs from the form of downstream 30 as the shock wave in the stove, thereby bombards on surface to be cleaned and generation calorifics and impact mechanically, so that dirt is fluffed.The pressure combustion product that to and then discharge from the pinking pipeline after the ripple, the product that row comes occurs as the form of jet and further finishes cleaning course (for example removing the material that has come loose) from downstream 30.After discharging combustion product, perhaps carry out simultaneously with the discharge combustion product, by (for example purging mouthful 100 introducing purge gas, air and/or nitrogen from the same source that is used to provide primary oxidant) (carry out immediately, perhaps carrying out (it can manually be determined or be automatically definite by control and monitoring system) according to regular or irregular interval subsequently so that repeat following one-period so that displace and make the pinking pipeline to be full of purge gas final combustion product.Randomly, can keep the baseline stream of purge gas between the cycle, so that prevent from upstream to permeate and be convenient to help the pinking pipeline is cooled off from the gas in the stove and particle in feed/drain.
In various implementations, internal surface area significantly can be increased to and exceed by for outside cylindrical and Frusto-conical the surface area that the section inner surface provides nominally inner surface increases device.Increase device and can help effectively to realize that detonation to detonation transition or help keeps detonation wave.The inner surface that Fig. 4 shows on the inner surface that is applied to one of principal part section 60 increases device.Nominally exemplary increase device is the Chin spiral, but also can use other to increase device, for example Shchelkin spiral and Smirnov chamber.Spiral is formed by helical form member 120.Exemplary member 120 forms the form of the hardware (for example stainless steel metal line) with circular cross section, and its diameter of section is approximately 8-20mm.Alternatively, also can use other cross section.Exemplary member 120 keeps being separated by by a plurality of staves 122 and portion's section inner surface.Exemplary stave be cross section and materials similar in member 120 and welding thereon with the inner surface of dependent part section 60 on bar.This increase device also can be used to provide in advance detonate, to replace relating to the aforementioned techniques of different feeds and different burner cross sections or replenishing as aforementioned techniques.
This equipment has widely to be used.For instance, just in typical coal furnace, equipment can be applied to: suspension or two-stage superheater, convection channel (primary superheater and economizer bundle); Air preheater; Selecting catalyst remover (SCR) washer; Dust storage chamber or electrostatic precipitator; Economizer hopper; No matter be to be positioned at heating surface or other local lime-ash or other heat/gather, or the like.Similarly possibility is present in other application, comprises that oil burner, black liquor recovery boilers, biological fuel boiler, waste recovery utilize stove (refuse furnace), or the like.
The various systems that are used to monitor and/or control the operation of Detonative cleaning apparatus can be provided.The realization of any specific control and monitoring system all may be subjected to comprising the influence of the physical environment that structure is set of the character on container and surface thereof and configuration and combustion pipe.Schematically show in a plurality of aspects of container 200 among Fig. 6.At this aspect place, settling a plurality of combustion pipe 202A-D.In the exemplary embodiment, the lower exit of pipeline is placed in the inside of container, and upstream extremity is positioned at external container.Although shown pipeline is straight type, pipeline can be the non-direct type configuration, so that in the desired position and along required direction discharging shock wave.Each pipeline and an interface module 204A-D are closely related, and it may provide controls the part of various operational factors (for example comprise the introducing of fuel and oxidant, purge and the introducing of refrigerating gas, ignite or the like).Other details of example interface module is discussed hereinafter.Given container aspect also can comprise sensor 206 and 208.Yet sensor does not need to be exclusively used in specific aspect.Similarly, pipeline also can not be exclusively used in specific aspect and also be not limited to discharge in the parallel plane the position to.Sensor can be exclusively used in particular conduit (for example, near the outlet of certain relevant pipeline or near the stove surface by this pipeline cleaned) or can be in more generally on the position.Sensor can detect one or more in hot state, pressure, stream, electrochemical conditions and/or the visual condition.To discuss in more detail the ruuning situation of illustrative sensors below.
