Definitions
- the invention relates to a device and a method for maintaining and operating a flame according to the preamble of the claims.
- the object of the present invention is to avoid the disadvantages of the prior art, in which a device and a
- the essence of the invention is the controlled ignition of a fuel gas mixture by the combination of an ignition source, with a flame.
- An ignition source is the energy that triggers the oxidation or combustion of the fuel gas mixture. This can be in particular a Corona opinion, the Barierreentladung.
- the flame-forming gas mixture is passed through or passed by the ignition source, so that a simultaneous ignition of the over the entire burner width is possible.
- the pulse frequency, the pulse ratio (On: Off) and / or the ignition of the ignition source can be varied over wide ranges, resulting in a high variability of the flame geometry and the flame parameter leads.
- the deposition behavior of the layer-forming components or the various surface modifications can be influenced in a targeted manner.
- FIG. 1 shows an embodiment of the device according to the invention in the operating state in an overview and Fig. 2: the embodiment of FIG. 1 in a cross section.
- the device according to the invention shown in Fig. 1 consists of a burner (1), a burner attachment (2), an anode (3), an operating state existing flame (4), a dialectic (5), a cathode (6) and a Exit geometry (7).
- a burner attachment (2) is mounted, on which in turn the electrically disabled barrier is mounted.
- the electrically impeded barrier consists of an anode (3) and a cathode (6) insulated with a dialectic (5).
- a non-combustible gas mixture can be introduced, which can be ignited via the dialectically impeded barrier, wherein the flame geometry is controllable by the barrier voltage and / or the pulse width of the barrier discharge.
- a non-combustible gas mixture can be produced inter alia by reducing the proportion of fuel gas in relation to the oxygen content (for example, from 5% to 2.75% in the case of propane gas). This reduces the required fuel gas concentration and thus the fuel gas consumption by more than 40% compared to conventional burners.
- Reactive and / or layer-forming substances or components such as, for example, organometallic compounds or suitable halides or hybrids, can be admixed to the fuel gas mixture either in powdery form, in gaseous form or in liquid form as a mixture (for example a solution or as a single component).
- This admixture with the fuel gas can be done either before the ignition of the same and thus before the ignition source, such as.
- the corona or barrier discharge or only after passing through the fuel gas mixture by the ignition source (corona or barrier discharge).
- a fuel gas for the flame can serve both organic gases and hydrogen.
- Oxygen is added to this fuel gas in an inert gas stream, it being possible for both nitrogen and noble gases to serve as the inert gas.
- the burner used is a commercial 300 mm long burner. On the burner, a 270 mm long and 30 mm high ceramic attachment with a 2.5 mm wide gap geometry is screwed on. At the upper edge of the gap, a cathode of Kanthai insulated with a 1 mm aluminum oxide alumina is attached over the entire width of the burner. The anode of Kanthai is adjusted parallel to the cathode with a distance of 2.5 mm. Between anode and cathode 100 kV barrier voltage are applied. The voltage source consists of a HV generator with a clockable input to which a function generator is connected. At the burner inlet, the propane fuel gas with the 0.6% precursor TMS (tetramethylsilane) is admixed via a Ventoridüse. The following volume flows are used:
- the pulsed clocking of the barrier voltage with 50 Hz in the ratio (On: Off 1: 2) achieves an optimal homogeneous deposition (30 nm) on glass samples, which passes at a distance of 20 mm at a speed of 170 mm / s under the flame become.
- a mixture of fuel gas, oxygen-containing inert gas and a film-forming gaseous, liquid or solid powdery additive by means of an ignition source (e.g.
- the ignition source for example, barium discharge is pulsed in the range between 0 Hz to 100 Hz, with a pulse ratio (on / off) of 2: 1 to 1: 3,
- the gas mixture or parts thereof pass through the ignition source (for example barrier discharge), the gas mixture or parts thereof at the ignition source (e.g.
- alkane preferably propane, butane or methane are used individually or in mixture,
- a hydrocarbon or a mixture of hydrocarbons is used as a fuel gas.
- the mixture in the composition is preferably below the explosion limit and does not form a self-supporting flame, Air or an oxygen-containing inert gas is added to the fuel gas and the mixture is preferably below the explosion or ignition composition,
- the mixture of air and propane gas is used in the ratio> 20 to 1, preferably 23 to 1 to 40 to 1,
- the layer-forming component separate from the carrier gas and fuel gas, is mixed with it after passing the ignition source (for example barrier discharge),
- the ignition source for example barrier discharge
- the fuel gas and the carrier gas pass the ignition source (e.g., barrier) and the film forming components pass it before the ignition
- the layer-forming component is an organosilicon or organometallic compound
- the layer-forming component is a hydride or halide
- the layer-forming compound is admixed with an organic liquid, preferably an alcohol,
- the layer-forming component is a metal salt dissolved in an organic, especially alcoholic, medium
- the ignition source e.g., barrier discharge
- the ignition source is formed in the form of a linear gap
- the ignition source e.g., barrier discharge
- the ignition source e.g., barrier discharge
- the gas guide through the ignition source (for example barrier discharge) has a vertical profile, the barrier preferably being arranged at the narrowest part of the vertical profile, the exit geometries used being different therefrom and
- Individual devices according to the invention can be arranged in cascades next to one another or behind one another over a substrate can be operated so that large areas of this substrate can be applied to the substrate by the deposition of film-forming substances or components from the flame.
- the maintenance / operation of a flame is made possible by means of a barrier discharge, wherein the flame is pulsed (flame "on” / flame “off”) continuously or discontinuously switchable.
