Definitions

  • Combustion equipment for pulverized solid fuels of known boilers for thermal power stations, or possibly ovens comprises, in addition to the main burners, ignition and combustion support burners whose function is to ensure start-up operations at cold and assistance at low loads of the main burners.
  • the document EP-A-0 057 895 describes a device for direct ignition of poor pulverized solid fuels in cold combustion chambers, and for supporting combustion at low loads. It comprises a make-up and ignition igniter operating with gas produced by the gasification of lean fuel and a main igniter operating with pulverized lean fuel. The combustion air sent to the igniter outlet is put into turbulence. This device requires that one has the gas produced by the gasification of the lean fuel. It does not provide means for translating the conduit for introducing pulverized solid fuel, or a flame detection device.
  • Document DE-C-916 663 relates to a device for introducing solid fuel sprayed into a burner comprising an axial tube movable in translation inside an annular tube for introducing secondary air. But the burner does not have a refractory orifice, or a conduit for introducing tertiary oxidizing gas, neither an ignition member, nor a flame detection member.
  • Document US-A-4 381 718 relates to a burner having in common with the present invention the members a), b), c), d), e) and f) above.
  • the conduit for the introduction of pulverized solid fuel is fixed, and it does not include a flame detection device.
  • the object of the present invention is to provide an ignition burner and support for combustion using pulverized fossil fuel, which has a lower operating cost than an ignition and support burner for fuel oil or gas, and easily adapts to frequent stops and prolonged operations at low load.
  • the ignition and support burner for solid atomized fossil fuel according to the invention is characterized in that the conduit for introducing the solid atomized fuel is provided with translation means making it possible to adjust the length of the premix chamber of the solid fuel and of the first fraction of secondary oxidizing gas lying between the end of this duct and the inlet of the flue gas, and in that a flame detection device is arranged near its flue gas.
  • the burner according to the invention is provided with means for adjusting the respective flow rates of the first and second fractions of secondary oxidizing gas in the annular conduits.
  • the ignition and support burner according to the invention preferably comprises an additional igniter consisting of one or more injectors of liquid or gaseous fuel distributed in the wall of the flue.
  • the invention further extends to combustion chambers with main burners and ignition and support burners for atomized fossil fuel.
  • each ignition and support burner is arranged between two main burners, vertically or laterally with respect to a main burner and at the level thereof, but in this case, the third conduit for introducing tertiary oxidizing gas is concentric with the flue and surrounds it.
  • each ignition and support burner is in the axis of a main burner, or placed in the arrival of secondary oxidant gas therefrom, or even laterally adjacent thereto, but in this case, the third conduit for introducing tertiary oxidant gas is concentric with the flue and surrounds it.
  • the tertiary oxidant gas of the ignition and support burner can also be introduced in part by the main burner.
  • the axial pipe or tube 1 provides a central supply of pulverized coal transported by primary air in relatively dense phase (several kg of coal pulverized per kg of air, and for example from 4 to 10 kg of coal per kg of air).
  • This tube is surrounded by a first duct or annular tube 2 for secondary air inlet, coming from the duct 3, at a flow rate adjustable by a flap 4.
  • the axial tube 1 can slide inside the annular tube 2, of which it crosses the wall by a seal 5 allowing its translation.
  • the periphery of the end of the tube 1 is provided with fins 6 for rotating for the secondary air coming from the annular tube 2. These fins 6 make it possible to produce, at the outlet of the tube 1, by turbulence, an intimate mixture of the fuel and part of the air.
  • the air arriving through the annular tube 2 can be preheated to promote the ignition of the fuel.
  • the axial position of the end of the axial tube 1 is adjustable by means of a handle 21 for controlling the translation of this tube, which makes it possible to modify the length L, and consequently the volume of a premix chamber 10, between the end of the axial tube 1 and the bottom of the outlet 12, so as to adapt it to the flow rate and to the quality of the powdered coal admitted by the tube.
  • the second duct or annular secondary air introduction tube 7 is supplied by the duct 8. It is provided with a flow adjustment flap 9, and is equipped at its end with rotation fins 11. L The air arriving through the annular tube can be preheated to promote ignition of the fuel.
  • the flow rates and proportions of air passing through tubes 2 and 7 are adjusted according to the quality of the coal.
  • the opening itself is provided with a refractory lining 13.
  • This opening comprises an igniter 15 of low power (of the order of 1% of the total power of the burner), which can operate either with gas or with fuel oil domesticated. It can be replaced by an electric igniter, with arc periodically spouting between electrodes.
  • an additional gas igniter is arranged in the quill. It consists of several injectors such as 16, 17 distributed in the wall of the flue in the ignition zone.
  • a flame detector 20 which also monitors the flame of the pulverized fossil fuel.
  • Tube 1 Primary air (tube 1) -15 to 30 Kg / h (charged with 4 to 10% of coal / Kg of air).
  • First secondary air (tube 2) at 20 ° C to 300 ° C 50 to 300 Kg / h.
  • Second secondary air (tube 7) at 20 ° C to 300 ° C - 50 to 300 Kg / h.
  • the length of the premix chamber is adjustable between 100 and 500 mm depending on the flammability of the carbon.
  • FIG. 2 represents an arrangement of an ignition and support burner with respect to the main burners, in the case of a boiler hearth with tangential heating.
  • the ignition and support burner 22 is arranged between two main burners 23, 24 of rectangular section each of which is surrounded by a rectangular opening 25, 26 for introducing secondary air and framed between two rectangular orifices (27, 29 ; 28, 30) secondary air intake.
  • the orifices 27, 28 are used both for the admission of secondary air to the main burner and of tertiary air to the ignition and support burner. In such a provision, admissions 18, 19, as mentioned in Figure 1, are deleted.
  • FIG. 3 represents another possible arrangement of the ignition and support burners with respect to the main burners, in the case of a boiler hearth with tangential heating.
  • the main burner 31 is arranged on an edge of the hearth, of rectangular cross section.
  • the ignition and support burner 32 is disposed laterally, on the face 33 of the hearth adjacent to this edge, in a circular opening obtained by deforming at this location the tubes constituting the wall of the hearth.
  • the ignition and support burner conforms to Figure 1.
  • FIG. 4 shows a relative arrangement of the main burners and of the ignition and support burners in a front-heating boiler home.
  • the main burners 41 are distributed in two rows on the face 40. They comprise an external tube 42 and an internal tube 43 which delimit a central inlet 45 for primary air and a peripheral inlet 46 for secondary air.
  • the ignition and support burners 44 are arranged in the axis of the main burners 41. These ignition and support burners 44 conform to that of FIG. 1, but in this case the tertiary air intakes 18, 19 are deleted.
  • Figure 5 shows another possible arrangement.
  • the main burners 51 are distributed in two rows on the face 50. They comprise an external tube 52 and an internal tube 53 which provide a central inlet 55 for primary air and a peripheral inlet 56 for secondary air.
  • the ignition and support burners 54 are arranged in the secondary air inlet of the main burners 51. In this case also the tertiary air inlets 18, 19 of the ignition and support burners 54 are eliminated.
  • Figure 6 shows another possible arrangement.
  • the burners 61 are distributed in two rows on the face 6 0 . They comprise an external tube 62 and an internal tube 63 which delimit a central inlet 65 of primary air and a peripheral inlet 66 of secondary air.
  • the ignition and support burners 64 are each in an adjacent position relative to a main burner 61. In this case, the ignition and support burners 64 are in accordance with that of FIG. 1.
  • the ignition and support burners can be supplied with the same charcoal as the main burners, or with charcoal of different nature and / or particle size.
  • ignition and support burners can operate independently of the main burners.
  • the invention can also be applied to burners or hearths burning lignite.
