In each figure, identical reference number and symbolic representation components identical.
The specific embodiment
Fig. 1 shows the stove 20 with three exemplary relevant soot blowers 22.In the embodiment shown, shaft forms the form of positive parallelepiped, and soot blower all is associated with the single common wall 24 of body of heater and is placed on the equal height along wall.Also can adopt other configuration (for example having one or more soot blowers etc. on each aspect in individual sootblower, a plurality of aspect).
Each soot blower 22 comprises the microscler combustion pipe 26 that extends from end 28 downstreams to abuts wall 24, upstream (for example far away/inlet) (for example near/outlet) end 30 away from furnace wall 24.Yet randomly, end 30 can suitably be positioned at stove.In operation during each soot blower, the burning that is positioned at the fuel/oxidant mixture of pipeline 26 is beginning so that the generation detonation wave near upstream extremity (for example the upstream of duct length 10%).Detonation wave is discharged from downstream as shock wave with relative combustion gas, so that the surface in the internal volume of stove is cleaned.
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.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 an exemplary embodiment, oxidant is for example oxygen of substantially pure of first oxidant.Second oxidant can adopt the form of 42 workshop airs of carrying from the center air source.In an 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 sources 32 is connected on the associated conduit 26 by the suitable pipe fitting 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 (discussing hereinafter) with source 32.
Fig. 2 shows the more details of exemplary soot blower 22.Exemplary quick-fried vibration tube road 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 66 that is arranged in wall and ends at the downstream that is exposed to 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 aerodynamics.Exemplary pipeline portion section material is metal (a for example stainless steel).If provide suitable supporting and cooling device, outlet 30 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.
Total length between the end 28 and 30 can be 1-15 rice, and is narrower, is 5-15 rice.The fuel/oxidant charging can import the pinking pipe interior according to different modes.One or more different fuel/oxidant mixtures can be arranged.This mixture can carry out premixed in pinking pipeline outside, perhaps can or mix after import pipe at the import pipe place.Fig. 2 shows pipe configuration and becomes to be used for to import respectively two kinds of different fuel/oxidant combinations: pre-detonating agent combination; With main combination.In an exemplary embodiment, at upstream primary importance place, the one or more ports 92 in one or more pre-detonating agent fuel injection pipes road 90 duct couplings are so that limit the fuel injection tip.Similarly, one or more pre-detonating agent oxidant conduit 94 can connect oxidant inlet port 96.Purge gas pipeline 98 can connect purge gas port one 00 similarly at upstream end more.Igniter/trigger 106 (for example spark plug) can be positioned near the upstream extremity of combustion pipe.
In an exemplary embodiment, 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.In an exemplary embodiment, fuel is hydrocarbon.In special one exemplary embodiment, two kinds of fuel are identical, and but they are drawn from single fuels sources mix with different oxidants: 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 oxidizer composition and also can be used as selection.
During operation, begin the place, except having air (or other purge gas), when beginning, be sky in the combustion pipe in life cycle.Pre-detonating agent fuel and oxidant import by related port subsequently so that filling upstream portion section (for example just having surpassed main fuel/oxidant port).Can cut off pre-detonating agent fuel and oxidant stream then.The pre-detonating agent fuel of filling and the exemplary volume of oxidant account for the 1-40% of combustion pipe volume, and be narrower, accounts for 1-20%.Import main fuel and oxidant then, so that the combustion pipe residual volume of filling definite part (for example 20-100%) roughly.Cut off main fuel and oxidant stream then.Import pre-detonating agent fuel and oxidant through main fuel/oxidant port before this, just eliminated between pre-detonating agent and main charging, forming air or other does not fire the risk of piece greatly.This can prevent that combustion front (combustionfront) from moving between two chargings.
Along with the importing of charging, thereby triggered the spark case so that provide the spark discharge of trigger to light pre-detonating agent charging.Pre-detonating agent charging is chosen to the chemical property of very fast burning, and therefore in part 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 can 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 is discharged product and is occurred also further finishing cleaning course (for example removing the material that has fluffed) from downstream 30 as jet.After the venting combustion product, perhaps carry out simultaneously with the discharge combustion product, (for example import purge gas by purging port one 00, air and/or nitrogen from the same source that is used to provide primary oxidant) so that final combustion product displaced and make the pinking pipeline be full of purge gas and repeat following one-period (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).Randomly, can keep the baseline stream of purge gas between the cycle, upstream permeate and help to cool off the pinking pipeline from the gas in the stove and particle so that prevent in feed/drain.
This equipment can have widely to be used.For instance, just in typical coal furnace, equipment can be applicable to: suspension or two-stage superheater, convection channel (primary superheater and economizer bundle); Air preheater; Catalysts selective remover (SCR) washer; Dust storage chamber or electrostatic precipitator; Economizer hopper; Be positioned at heating surface or other local lime-ash or other heat/gather etc. no matter be.Similarly possibility is present in other application, comprises that oil burner, black liquor recovery boilers, biological fuel boiler, waste recovery utilize stove (refuse furnace) etc.

In order to carry out signal and communication, module and sensor are connected on the hub (for example Ethernet) 210 by communication line 209.In an exemplary embodiment, sensor is connected on the hub (hub) by module (for example being connected on the module by communication or signal line).Drop into (for example fuel, oxidant, purge gas, cooling agent, electric power etc.) in order to carry out the thing amount, module is connected on the center fed unit 212 by fluid and power circuit 213.Hub and feeding unit can be specific aspect special use, shared or some combinations.For carrying out signal and communication, hub (for example by network line 215 as optical fiber circuit, ethernet line etc.) is connected in the control and monitoring system 214 (for example control/monitoring software of all-purpose computer operation) of equipment, and it is special-purpose or be positioned at the maincenter of the container group in somewhere (for example giving locking equipment) that it can be special container.Feeding unit can be connected in the system 214 by hub 210 similarly or can independently exist.System 214 keeps in communication with Long-distance Control and monitoring system 216 and connects.System 216 can keep reliable communication to be connected with the many systems 214 that are positioned at many diverse locations place.Yet, in this case, system 216 can with those systems 214 in one or morely be positioned at same position and be positioned at diverse location with other system.Exemplary communication between system 216 and the system 214 for example realizes the internet by wide area network 217.Also can use the alternative public or dedicated network or other communication system.Feeding unit 212 self can be from being positioned at tank field 218 (for example central tank field of equipment) at a distance by being used to supply the circuit 219 of non-air gas and other fluid, and from suitable workshop air and power supply (not shown, it also can be the central source of equipment) supply.System 214 can keep in communication with some center systems.For example, system 216 can be the center system of carrying out this owner/operator of communication with the system 214 that is positioned at equipment owner/operator's distinct device place.Center system 223 can be directly or is undertaken by the system 216 and the system 214 of different owner/operators' distinct device the maintenance supplier's of communication center system.Finally based on by sensor 206 and 208 data that provided, but system's 214 reporting systems 223 need repairing or routine maintenance or maintenance and routine maintenance very suitable (any one system place makes decision in system 214,216 or 223).
In an exemplary embodiment, emergency control panel 220 is positioned near near the system 214.Exemplary emergency control panel comprises one or more status lamps and one or more switch (for example used red/green status lamp and the emergency cut-off switch of each pipeline adds total cut-out switch that all pipelines are shared).They link up by the circuit 222 that extends to each interface module.If control system breaks down, thereby maybe can stop by system 214 and 210 pairs of pipelines of hub and control (being safety guarantee), then cut off switch can be by technical staff tripping operation in case the safety that ensures pipeline (for example, fuel shutoff and oxidizer valve, forbid a little lighting a lamp, so that cut off safely and/or forbid related channel program).Interface module self can be provided with according to the error protection pattern, so the disconnection of line related 215 or 222 will cause module to change safe mode into.
It is the series connection that is used for the sensor (or back end signal treatment circuit) of a plurality of (for example owning) pipeline that exemplary sensor connects.Series circuit can seal usually.If when pinking takes place on any pipeline, then sensor will switch (toggle) circuit and then will disconnect.Signal processing circuit can be configured to keep disconnecting circuit to disconnect the sufficiently long time (for example greater than one second) so that controller reads.Just in this point, when circuit does not disconnect if the order particular conduit is lighted a fire, just then controller can know which pipeline pinking occurs and lost efficacy.Behind the successful cold run predetermined quantity of given pipeline, control system can and disconnect this particular conduit (for example, allowing the residue pipeline to remain in operation simultaneously) to operator's warning.
The detection of this kind pinking (or its disappearance) can be in conjunction with other control aspect and input, just as determined in the U.S. Patent Application Publication 20050199743 referred to above.
More than one or more embodiment of the present invention are described.Yet, should be understood that and can make various changes.For example, the present invention is applicable to various industrial equipments and various soot blower technology.For example, this principle comprises fixing and expandable/contractile unit applicable to various existing or still at the knock tendency cleaning equipment of exploitation.The aspect of existing device and technology can influence the aspect of any specific implementation mode.Correspondingly, other embodiment is also within the scope of following claim.
