Definitions

  • the present invention relates to the field of lighters and more precisely lighters designed to generate a colored flame controlled.
  • the present invention now aims to provide new ways to improve the performance of lighters colored flame.
  • the object of the present invention is in particular to propose a lighter generating a flame of lasting stability.
  • the present invention follows lengthy work on the study of the lighter flames, which led to the findings following.
  • Diffusion flames are characterized by the fact that the fuel and oxidizer are not mixed before reaching the area where they will burn.
  • the classic lighter and candle flames are typical examples of diffusion flames.
  • Important phenomena with these flames are diffusion phenomena of molecules of oxygen from the air to the center of the flame and diffusion of the molecules of fuel from the center of the flame to its periphery; they are the ones govern the shape and behavior of these flames.
  • Diffusion flames are often stabilized at the exit of a cylindrical tube. If the gas flow of fuel is sufficiently slow at the outlet so as not to create turbulence, we speak of a laminar flame. The usual form of such a flame is that shown in Figure 1.
  • the most commonly visible part is a yellow area b which is limited by a bluish border d. This bluish thickness d is not very bright compared to area b colored yellow. This set is surrounded by a layer of hot burnt gases f which rise mainly under the action of natural convection. These hot gases do not are usually not visible.
  • the yellow part b is characteristic of the presence of carbon, called soot in the language of the "combustionist". These soots are formed by the decomposition of carbonaceous molecules in fuel fuel under the action of heat. In this zone oxygen is in amount less than stoichiometry. Combustion is poor. Brought to high temperature when they approach the reaction zone, this soot emits a yellow-orange light, which makes the flame shine. They then burn on passing the reaction zone d and disappear in general. The hottest place is the reaction zone d of color blue. It is in this area that the chemical reactions take place heat generation. It roughly corresponds to the place where the fuel or fuel is mixed in proportion stoichiometric with oxygen.
  • the mixtures could not be done at this place only by diffusion of molecules: the fuel, which is located on the axis of the burner, diffuses towards the bluish lateral zone d, and the oxygen, present in the outside air, also diffuses laterally to supply areas where it is not initially present.
  • burnt gases mainly CO2 and water vapor
  • burnt gases mainly CO2 and water vapor
  • the oxygen must diffuse laterally from the outside air towards the bluish zone through a layer of burnt gases of thickness ⁇ , which depends on the height.
  • the width of the burnt gases is obtained: ⁇ ⁇ D 1/2 ox g ⁇ o ⁇ b ⁇ b -1/4 z 1/4 g represents the acceleration of gravity, ⁇ b the density of the burnt gases and z the height from the burner. It should be noted that the acceleration in the burnt gas can reach 5 or 6 times the acceleration of gravity.
  • the flames no longer remain stable. They start to oscillate vertically with a frequency of about fifteen Hertz. Flames elongate and retract periodically with an amplitude of oscillation 1 or 2cm. Flames are said to enter the "flickering" regime. The oxygen supply is improved and the average length of the flames is no longer linear with flow. With even higher flow rates flames become turbulent, i.e. the jet at the outlet of the tube is too fast to stay laminar. It goes into turbulent regime and the gas trajectories are then very disordered, although the direction mean remains parallel to the axis of the tube. These movements of agitation turbulent promote mixing between fuel and oxygen; other says the molecules will meet more quickly. This translates for a flow given by a constant flame height. However, in this turbulent regime, the flame height now depends on the speed Release.
  • the flames are lifted as soon as the speeds of output reach 7 or 8m / s.
  • the lift-off distance changes regularly with the speed and it is possible to reach several tens of centimeters for high speeds.
  • the flames are turbulent and often noisy. The flows and the speeds are such that the flames are forced to stay on the axis and they are very little sensitive to the effects of the agreement natural.
  • the "lifted" flames allow the fuel to partially mix with air before burning and to have a base of pre-mixed flame. This results in better combustion and in particular lower soot production. So the yellow part is less bright at the base of the flame and blue dominates.
  • premix are characterized by the fact that the fuel and the oxidizer are mixed before reaching the burner outlet.
  • the premix is achieved in a certain ratio which is defined by a wealth.
  • Wealth 1 corresponds to a stoichiometric mixture, it is say that the fuel and the oxidizer are in ideal proportions to completely react. If the mixture contains too much oxygen, we will speak of a flame “poor” in fuel and its richness will be less than 1. Conversely, we will speak of a "rich” flame when there is too much combustible ; wealth will then be greater than 1.
  • the flame spreads with constant speed.
  • the speed of deflagration of a methane-air flame, with a richness of 1 is 0.40 m / s.
  • V F V o sin ( ⁇ / 2). So if V o increases, the flame angle decreases and the flame is higher. The same applies if the flame propagation speed decreases. The speed of propagation depends on the composition of the mixture, but it passes through a maximum towards stoichiometry; that is to say that, for a fixed delivery speed, the flame is shorter if the mixture is close to stoichiometry.
  • the fuel premix flames are usually blue clear. They only start to emit yellow soot if the mixture is rich in fuel (too poor in oxygen).
  • a lighter 10 which includes a tank 20 adapted to receive combustible material 30 associated with flame coloring agents, means 40 capable of ensuring relaxation combustible material 30, means 50 capable of conveying the material fuel 30 to the expansion means 40 and means 60 suitable for ensure the ignition of the combustible material 30 at the outlet of the means of trigger 40.
  • the lighter 10 further comprises means 70 forming a valve capable of controlling the fuel release time 30.
  • the means 40 fulfill a double function: they form a static mixer and serve as regulator for fuel and agent of coloring associated with it.
  • the expansion means 40 are formed from an element which has no capacity adsorption, and therefore more precisely hydrophobic (no capacity water absorption), organophobic (no absorption capacity of organic molecules) and inorganophobic (no absorption capacity of minerals).
  • the expansion means 40 are formed of a porous material.
  • hydrophobic, organophobic and inorganophobic recommended in the context of the present invention allows avoid condensation on this element when opening the valve 70 and relaxation.
  • fluorinated polymers such as polytetrafluoroethylene (or PTFE) or polyolefins, such as in particular high density polyethylene (or PE).
  • the implementation by dissolution essentially consists in carrying out a mixture based on polymer and a solid filler, extrude and form a film using this mixture and dissolve the filler with a non-solvent of the polymer matrix.
  • Finely divided coloidal silica, granules of salts or equivalent means can be used as "fillers”.
  • surfactants such as sodium dodecyl benzene sulfonate.
  • a variant of the dissolution process can use a polymer of different nature of the matrix instead of the solid charge. This polymer is then extracted with a solvent.

  • the expansion means 40 are adapted to control a flow of fuel and associated coloring agent, upstream of the point inflammation, between 2 m / s and 8 m / s.
  • the lighter 10 is fitted, downstream of the fuel outlet, with a cover shown diagrammatically in FIG. 4 under the reference 80, comprising an orifice 82 of calibrated dimension, placed opposite the aforementioned fuel outlet, to reduce the fuel exit speed and thus avoid blowing flame and therefore stabilize it.

  • the means 50 adapted to convey the fuel 30, include, upstream of the ignition point, a venturi pump 100 (or “depression system”) adapted to control intake oxygen in order to obtain the stoichiometric ratio and optimize the combustion.
  • the convergent 122 of the jet pump is supplied by the fuel from tank 20. This prevents bad combustion of the fuel 30 does not generate a disturbing color and allows the coloring agent to fully produce its effect.
  • a Venturi pump provides an air supply at the base of the burner, which allows to start a premix which in turn allows oxidation very fast soot.
