Description of drawings

When reading with reference to the accompanying drawings, will know other purpose of the present invention, feature and advantage from following description.In the accompanying drawings, like reference numerals is represented counterpart in all views:

Fig. 1 is the viewgraph of cross-section according to burner of the present invention.

Fig. 2 is the top view according to burner of the present invention.

The specific embodiment

In the detailed description below, described many details and fully understood so that provide of the present invention.Yet, it will be understood by those skilled in the art that the present invention can implement under the situation of these details not having.In other situations, can not make the present invention fuzzy thereby describe known method, step and/or parts in detail.Now will be in detail with reference to the preferred embodiments of the present invention, its example shown in the drawings.

Embody burner of the present invention and totally be designated 10 in the drawings, and comprise tubular body 11, this tubular body longitudinally axis 12 is arranged, extends through shell 13 passes shell 13 with formation passage 14.Shell 13 is connected to tubular body 11 by jockey 15.Shell 13 comprises the air intake pipe 16 of the sidepiece that is connected to shell 13 and is arranged to passage 14 opening opposing 40 with shell 13.The opening 40 that the inner tubular member 17 of qualification internal chamber 21 is passed shell 13 is arranged in the shell 13.Inner tubular member 17 comprises the chamber inlet tube 18 of the sidepiece that is connected to inner tubular member 17 and is positioned at the opening 19 of the end of inner tubular member 17.

Inner tube 25 comprises hollow pipe 26, and an end of this hollow pipe is fixed with thread head (screw head) 27, and another end of stretching out is fixed with fuel supply device 28, and wherein this thread head passes opening 19 and is arranged in the inner tubular member 17.Fuel supply device 28 comprises the fuel tap that is connected to hollow pipe 26, is used for fuel supplying so that start or keep burning.Air or be introduced into inner tubular member 17 by chamber inlet tube 18 such as other gas of steam.Inner tubular member 17 is substantially annular shape, and its free end 23 forms discharges outlet, so as air or other gas internally the internal chamber 21 of tubular element 17 flow into tubular bodies 11.Inner tube 25 is rotated with respect to longitudinal axis 12 with one heart by the whirligig (not shown).

The air that 27 pairs of hollow parts in the inner tube 25 are introduced from chamber inlet tube 18 apply the rotation concentric with longitudinal axis 12, and this air along the longitudinal axis 12 with discharge outlet 23 motions of screw towards inner tubular member 17.The free end 23 of inner tubular member 17 is tangentially introduced tubular body 11, to produce around the axis 12 of tubular body 11 advance circularly in an orderly way 41 air and the vortex mixed of being carried secretly particle.

Tubular body 11 has the supply pipe 24 of the tubular body 11 that is connected to burner 10.Supply pipe 24 is connected to feeder equipment 29, so that air 42 and solid combustible burning material 38 are incorporated into burner 10.Supply organ pipe 24a more than one can be connected to tubular body.Feeder equipment 29 comprises the gear-box 30 that is connected to motor 31, and this motor is used for the transmission screw rod 32 of drive arrangement in hollow shaft 33.Transmit screw rod 32 around hollow shaft 33 rotations, the solid combustible of supplying with the hopper 34 of carrying the sidepiece by being installed in hollow shaft 33 burns material or particle 38, and discharges in the discharge end of hollow shaft 33.Burn material 38 by introducing tubular bodies 11 by supply pipe 24 such as solid combustible from the air of feeder equipment 29 or the stream of other gas with coal, timber and other burnable solid of particulate forms.

Between shell 13 and inner tubular member 17, space 22 is set.Tubular body 11 is tapered in a side, and is provided with the outlet 36 that is used for final burning.Conical in shape supplies a pattern the time (mode time) to a certain extent, burns before it flows into outlet so that solid combustible burns material 38.If the hollow parts of tubular element is a size, then possible material 38 is with speed outflow faster.High speed or pressure-air are introduced into shell 13 by air intake pipe 16, and with turbulization air in the tubular body 11 of burner 10, this further increases the air mixing uniformity and significantly improves the burner combustion performance.This also make heat energy that burning produces enough longitudinally axis 12 propagate long distance and arrive outlet 36, and therefore improve distributing of heat that burner 10 produces.Cause that with vortex mixed solid combustible burns material 38 and is driven with high speed along circular path from the high-speed air of inlet tube 16 in tubular body 11 from the air of inner tubular member 17.Preferably, air enters 44 tapering parts to guarantee all particle efficient burnings.

In the operating period of burner 10, solid combustible burns particle 38 and introduces tubular body 11 by supply pipe 24 by feeder equipment 29, and this solid combustible burns particle and carries by transmitting screw rod 32.In inner tubular member 17, start burning by fuel, and introduce air from chamber inlet tube 18 by air blast by fuel supply device 28.The heat that produces during burning in inner tubular member 17 is transmitted to leave in the mode of spiral flow and discharges outlet 23 and enter tubular body 11, and combustible material is introduced into this tubular body 11 from supply pipe 24.The high-speed air that is incorporated into the tubular body 11 from air intake pipe 16 causes that the eddy current heat and the entrained particles 38 of tubular element 17 generations internally are driven with high speed along circular path, therefore increase the burner combustion performance in tubular body 11.In this embodiment, the air intake pipe is identical with supply pipe.In another embodiment, the air intake pipe can be an inlet 16.

As the skilled person will readily understand, the present invention can easily be embodied as other concrete form and not depart from necessary characteristic of the present invention.Therefore, think that present embodiment only is exemplary and is not restrictive that scope of the present invention is provided by claim rather than provided by aforementioned description, and intention comprises all changes that drop in this scope.
