Definitions

  • Means are provided in the head to enable the mixture for a slow burning rate to be distributed preferentially to .a selected section of one or several of the orifices thus constituting the slow burner.
  • the means may comprise a diffusing tube bringing the mixture into the head of the burner and distributing it through passages arranged so that the one or more corresponding to the selected section have lower pressure drops than those co-operating with the other flame outlet orifices.
  • the power at slow-rate is of the order of one-seventh of the nominal power. It is too great, in a general way, to maintain a liquid hot in a container, without reaching boiling point.
  • thermocouple safety device positioned close to the burner.
  • lt is therefore an object of the invention to provide very extreme slow burning rates, for example of the order of one-tenth to one-fifteenth of that of normal power, whilst avoiding the above-mentioned difficulties.
  • the power per unit surface will be easily increased, so that theintenthrough passages arranged so that the one co-operating 2 with the selected outlet cross-section above-mentioned has pressure drops distinctly less than those cooperating with the other outlet orifices.
  • the diffuser tube will have, on the side of the selected outlet section of the burner, a passage of large cross-section, whilst, to supply the other 1 outlet orifices of the burner, there will be provided on the periphery of said tube a certain number of small .or-
  • ifices adapted to make the mixture pass from the inside of this tube towards the one or more corresponding annular portions provided inside the head of the burner.
  • the gaseous flow is localised principally in front of the selected section whilst, from nominal flow-rate to the lower flow-rates, and at least to half flow-rate, the distribution of the gaseous mixture will be practically homogeneous over the whole perimeter of the burner.
  • the low pressure loss system that is to say through the above-mentioned low pressure drop passage, there will be supplied in priority the orifices of the selected section of the burner, of which thus the flames wil be able to retain a sufficientlength; resisting wind and capable in addition of co-operating with any ignition and/or safety devices.
  • the static pressure and the dynamic pressure will be sufficient both for overcoming all pressure drops and sup plying in practically uniform manner the various burner orifices.
  • the invention consists, apart. from the abovementioned features, of certain other features which are preferably used atthe same time and which will be more explicitly considered below.
  • FIGS. 1 and 2 show respectivelyin axial vertical section and in cross-section through the line II--II of FIG.
  • FIGS.3 and 4 illustrate similarly another embodiment of a burner according to the invention, comprising the use of various auxiliary members such an ignitor, a safety device, and wave tubes.
  • FIG. 5 is a sectional view taken along the lines v v of FIG. 2.
  • This burner is made to comprise, essentially and as is customary, a head 1 comprising a differing annular space 2, intended to distribute the combustible mixture to a plurality of outlet orifices distributed at the periphery of the burner or at least at a portion of this periphery, the said orifices consisting for example of crenellations 3 formed on the edge of a cover 4 applied on the head of the burner.
  • a diffuser member 7 arranged so as to enable:
  • a selected outlet section which will constitute the slow-burning orifices, for example two orifices 3, selected from the above-mentioned orifices 3, and being either of the same cross-section as that of the orifices 3, or a different cross-section (especiallY larger),
  • the diffuser 7, which can be fast to the cover 4 and applied, by its free edge, to the pipe 6, can include (FIGS. 1 and 2):
  • the diffuser 7 could be fast to the cover. It could be constructed in extension of the tube 6 as illustrated by way of modification in FIGS. 3 and 4, the orifices 10 being arranged for example in the shape of crenellations.
  • the respective cross-sections of the passage 8 and of the orifices '10, with respect to the orifices 3, and 3, 15, are of course suitable selected by the technician as a result of comparative tests, taking into account the desired results.
  • the cross-section of the passage 8 will be distinctly greater than that of the slow burning orifices 3,, Whilst in addition the overall crosssection of the orifices 10 will in general be such that these orifices lead to a higher pressure drop than that 6 due to the orifices 3 and 15.
  • the injector 5 delivers at full rate, that is to say for nominal burningrate, and that the pressures both static and dynamic are established in the head of the burner, the assembly ignites like a normal burner, at its nominal power. It is observed only that the two selected flames are a little bigger than the others.
  • the burner is changed suddenly to slow burning rate and the burner has also not had the time to heat up to its normal temperature, only the two selected flames remain lit, at least it is possible that this particular operation occurs.
  • the mixture supplies principally the orifices 3, but it also supplies the other cross-sections 3 and 15, in a way however which, the burner being again cold and the secondary air being in excess, cannot give rise to combustion.
  • the burner is heated, so that the air/gas mixture inside the burner is also heated, which involves a larger volume, hence a corresponding reduction in the proportion of air.
  • the increase in temperature has the effect of increasing the speed of propogation of the flame, which also facilitates ignition of the air/gas mixture.
  • the burner ignites at the orifices 3 and 15, with small slow burning flames.
  • the two selected flames have a relatively high heating power, in any case greater than that of the flames of a normal slow burning burner, and resist wind better,
  • thermocouple of an electro-element These flames are sufficient to supply the thermocouple of an electro-element.
  • FIGS. 3 and 4 it is shown how there can be installed for example:
  • thermocouple safety device at l3.
  • the ratio between the cross section of the passage 8 of the diffuser and the total cross section of the two selected orifices 3, is of the rsi afile
  • the total cross section of the orifices 10 of the diffuser is of thesame order of magnitude as the total cross section of the outlet orifices of the main flames.
  • the nominal and slow burning powers are for example
  • said diffuser member comprises a tube having passages arranged so that one or more of said passages correspond to the selected section and have pressure drops smaller than 'those passages co-operating with said other gas outlet 3.
  • the diffuser tube has on the side of the selected section, a large passage directing the mixture directly towards this section, and a plurality. of orifices of smaller cross section distributing the mixture to said annular space.
  • Burner according to claim 3 wherein the cross section of the large passage supplying the slowburner is several times greater than the selected section of the slow-burner orifices.
  • Burner according to claim 2 said being removable, wherein the diffuser tube is fast to said cover and has been adjusted on the end of the tube bringing the mixture from an injector.
  • Burner according to claim 8 wherein the passages of said diffuser are arranged in the form of castellations at the end of said tube under said cover of the burner. 10. Burner according to claim 1 wherein the slow burner is arranged so that its flames co-operate with an electric or electronic ignitor.
  • Burner according to claim 1 wherein the slowburner is arranged so that its flames co-operate with a wave tube.
