Definitions
- the present invention relates to a catalytic combustion device with vaporization of liquid fuel on a hot wall, thereby making it possible to optimize the preparation of the air-fuel mixture in a combustion zone.
- this technology is based on lowering the combustion temperatures. It allows the NO x to drop to around 20 ppm, but this reduction is often done to the detriment of carbon monoxide and unburnt fuel emissions, which are increased.
- Catalytic combustion is an attractive solution to meet the increasing severity of pollutant standards.
- the catalytic combustion chamber advantageously replaces the conventional burners, because it allows better control of the total oxidation of the fuel in a very wide range of values of the air / fuel ratio, thus making it possible to work under optimal conditions which reduce high emissions of nitrogen oxides, unburnt fuels and carbon monoxide.
- the essential characteristic of this particular type of combustion is to ensure the complete oxidation of the fuels at a relatively low temperature (below 1000 ° C.), compared with conventional combustion.
- catalytic combustion makes it possible to burn a wide variety of compounds.
- catalytic combustion is thus multiple: radiant panels and tubes, catalytic stoves, gas turbines, cogeneration, burners for boilers, catalytic sleeves for tubular reaction systems, production of hot gases in the field of direct contact heating and reactors with catalytic plates, etc.
- the possible fields of application of catalytic combustion are described in the literature for example in “Catalytic Combustion: Current Status and Implications for Energy Efficiency in the Process Industries, Heat recovery System & CHP, 13, n ° 5, pp 383-390 , 1993 ".
- Combustion catalysts are generally prepared from a monolithic substrate, ceramic or metal, on which is deposited a thin support layer consisting of one or more refractory oxides, with a surface and porosity greater than that of the monolithic substrate . On this support layer is dispersed the active phase most often comprising essentially metals of the platinum group.
- the most common reactor configuration is a reactor comprising several catalytic zones: the inlet catalyst (s) being more specifically dedicated upon initiation of the combustion reaction, the following serving to stabilize the combustion reaction
- This mixture must be produced as quickly as possible, and in the most homogeneous manner while limiting the risks of auto-ignition.
- the invention relates to a catalytic combustion device comprising a main combustion zone comprising at least one catalytic stage, at least one air / fuel mixing zone, said mixing zone comprising at least one pressurized air inlet, and means for injecting a liquid fuel, characterized in that the injection means project the liquid fuel onto a wall heated by the combustion of the air / fuel mixture in the area of main combustion so as to allow the vaporization of said fuel in contact with this wall.
- the invention it is possible to very substantially reduce the diameter of the liquid droplets by sending a primary liquid jet over a surface of temperature greater than the maximum boiling temperature of said fuel under the pressure conditions of the combustion zone.
- This primary liquid jet can advantageously come from any injector or spraying system known to those skilled in the art.
- injectors are used which allow primary spraying of the fuel with liquid droplets whose average diameter is between 5 and 60 ⁇ m (10 " ⁇ meter), preferably between 10 and 40 ⁇ m.

- ⁇ a temperature above or below 100 ° C at said temperature, preferably a temperature above or below 50 ° C at said temperature and very preferably a temperature above or below 20 ° C at said temperature.
- Control of the temperature of the wall will therefore condition the size of the droplets and may be carried out according to any technique known to those skilled in the art.
- Such an injection strategy has many advantages during the preparation of the air-fuel mixture, in catalytic combustion: - Compared to a conventional configuration of catalytic combustion device with premixer and catalytic section, an arrangement having such a mode injection allows faster vaporization of the liquid fuel, especially those with fairly high final vaporization temperatures. This is the case for certain diesel fuels for example. Under these conditions, the air-fuel premix can be obtained more quickly.
- the arrangement object of the present invention can also contribute to the cooling of the walls of the combustion or post-combustion zones or of the zone which conveys the hot gases to the expansion turbine.
- the hot wall on which the fuel is sprayed is the wall of the combustion or post-combustion zone or of the zone carrying the hot gases from the combustion or that of the starting equipment which can be for example , a flame combustion chamber, an electric heater or any other device known to man ] of Art.
- the means allowing the injection of the liquid fuel are injectors carrying out a primary spraying whose orientation and characteristics are calculated to obtain the most homogeneous possible distribution of the fuel in the air of combustion and the size of the droplets from said injector is between 5 and 60 ⁇ m, preferably between 10 and 40 ⁇ m and very preferably between 20 and 30 ⁇ m.

- This pilot burner can also be equipment known to those skilled in the art and reputed to emit little nitrogen oxides, such as for example systems in which combustion air is rotated in blades, with injection. fuel inside the blades, or part of the blades, or in the immediate vicinity of these blades.
- this comprises an air-fuel mixing zone 11 situated downstream of the distribution box 3, liquid fuel injectors with mechanical spraying 12 distributed evenly for example around the periphery of the mixing zone 1 1 and the catalytic section 5.
- the injectors 12 produce a jet of liquid fuel directed towards the hot wall 13 of the pilot burner 4, and make it possible to carry out a primary spraying of this fuel with liquid droplets whose average diameter is between 5 and 60 ⁇ m (10 '6 meter ) and preferably between 10 and 40 ⁇ m.
- This jet is preferably substantially perpendicular to the hot wall.
- substantially perpendicular it is understood that the angle between the surface of the hot wall with respect to the axis of the jet is very preferably between 80 ° and 100 °.
- this angle can be between 40 ° and 140 ° and preferably between 60 ° and 120 °.
- the wall 13 is heated by the combustion of the air / fuel mixture in section 5 and in contact with the hot wall, the liquid fuel is vaporized by dividing into very fine droplets of a few microns ⁇ (10 "s m) of average diameter which are entrained by the combustion air.
- the number of injectors, their orientation relative to the hot surface and the characteristics of the injectors are calculated by a person skilled in the art for obtain the most homogeneous distribution of the fuel in the gas flow, once the fine droplets are sprayed in.
- the air-fuel gas mixture then enters the catalytic section 5, which most often consists of one or more monoliths in parallel and or in series, in order to limit the pressure drops
- the catalytic section 5 most often consists of one or more monoliths in parallel and or in series, in order to limit the pressure drops

- the combustion air circulates in a substantially annular peripheral space 104.
- the fuel is introduced by means of injectors 105 fixed and substantially evenly distributed on the external wall 106 of the external wall of the annular space 104.
- injectors can be mechanical (without spraying assistance) or pneumatic (with spraying fluid assistance) or any other equivalent device.
- the jets produced by these injectors are directed towards the hot wall 107 which separates the annular space 104 from the zone 108 which can be an after-combustion zone or even simply a connection zone between the catalytic section 103 and the expansion turbine (not shown in the figure) and, in contact with this hot wall, the liquid fuel is sprayed into very fine droplets.
