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 half section of upstream 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.
