Abstract
The utility model discloses a highly efficient internal combustion type coal powder burning apparatus with an ignition source. The burning apparatus comprises an external cylinder, internal bushings of different levels, a central cylinder and a support block. The central cylinder in the internal bushings and internal bushings of different levels are concentrically arranged; sections are gradually enlarged level by level and are connected by the support block. The utility model is characterized in that the inside of the central cylinder, the internal bushings of different levels and the external cylinder is provided with a convex flame-stabilizing block. The apparatus can enhance the disturbance of air, improve the degree of turbulence, and enhance the combustion. At the same time, the apparatus can provide high-concentration coal powder for the ignition source and create high-concentration conditions for ignition of coal powder in the central cylinder. The flame-stabilizing block in the internal bushing of each level and the external cylinder can not only provide conditions for ignition of each level, but also can have the function of cooling the pipe wall of the internal layer; meanwhile, the apparatus can prevent slagging.
Description
Technical field
The utility model relates to pulverized coal combustion, is specifically related to a kind of steady flame piece of coal burner of the internal combustion type that is used to have incendiary source.
Background technology
Traditional industry coal-burning boiler ignition trigger and low-load combustion-stabilizing are to rely on to be installed on the oil inflame that near the oil burner the burner sprays into and to come firing coal-dust.Can address the above problem though be used for the coal burner of conventional fuel-economizing, have the bigger problem of igniting initial stage combustible loss, the inadequate shortcoming of burner internal combustion.
Summary of the invention
The purpose of this utility model provides a kind of internal combustion type pulverized coal burner that efficiently has incendiary source, be intended to overcome the technical deficiency of traditional Plasma powdered-coal burner to elementary firing coal-dust and multistage steady combustion existence, use this device simultaneously and make burner wide, flameholding the accommodation of coal, wind speed, wind-warm syndrome.
For achieving the above object, the technical solution of the utility model is achieved in that
A kind of internal combustion type pulverized coal burner that efficiently has incendiary source, the steady flame piece of one group of convex is laid at the interval in burner tube, and described steady flame piece is provided with on a place or sectional position, many places, constitutes single-stage or multilevel hierarchy.
Aforesaid a kind of internal combustion type pulverized coal burner that efficiently has incendiary source, the burner cylindrical shell comprises urceolus, inner sleeve at different levels, central tube and back-up block; Central tube and inner sleeve at different levels are placed with one heart in its inner sleeve, and amplify step by step in the cross section, and connect with back-up block; Be laid with the steady flame piece of convex in central tube, inner sleeve at different levels and urceolus inside.
Aforesaid a kind of internal combustion type pulverized coal burner that efficiently has incendiary source, on the barrel that is positioned at same cross section of the uniform or non-uniform centering tube in steady flame block gap, inner sleeve at different levels and urceolus inside, above-mentioned arrangement is multistage or single-stage.
Aforesaid a kind of internal combustion type pulverized coal burner that efficiently has incendiary source, the windward side that is shaped as of steady flame piece is plane or curved surface, lee face be shaped as plane or curved surface, described windward side or lee face and each barrel meets at right angles or acute angle.
Aforesaid a kind of internal combustion type pulverized coal burner that efficiently has incendiary source, steady flame piece is disposed in the exit of this grade sleeve or is arranged in inside.
Compared with the prior art the utility model has following good effect:
1, the interior steady flame piece of central tube has been strengthened the disturbance of air, improves the overheavy firing of turbulence degree, and the coal dust of high concentration is provided for incendiary source simultaneously, for the coal dust of lighting central tube is created superior condition;
2, the steady flame piece in inner sleeves at different levels and the urceolus has been strengthened the disturbance of air, improves the overheavy firing of turbulence degree, creates conditions for this grade igniting simultaneously, plays the effect of cooling inner layer tube wall again, also prevents slagging scorification;

The specific embodiment
Understand and the enforcement this patent for better, provide specific embodiment below in conjunction with accompanying drawing and describe the steady flame piece that originally is used for coal burner in detail.
Fig. 2 is the structural representation in cylindrical shell cross section, steady flame piece place, steady flame piece be uniformly at intervals with tube in.
In embodiment 1, what light at first is the dense side coal dust that enters after the deep or light separation of deep or light of process of central tube, then lights the dense side coal dust after the deep or light separation that enters the steady flame piece of process between central tube and the low one-level inner sleeve, lights step by step, amplify step by step, coal dust is fully burnt.Reduce combustible loss, improve efficiency of combustion, reduce NOx content.Under the effect of steady flame piece, have the air overheavy firing of strong turbulence degree behind the coal dust in incendiary source is lighted inner sleeve, improve efficiency of combustion.For subordinate's ignition provides sufficient energy.
The quantity of steady flame piece can be selected by calculating, and the planform of steady flame piece can be various.
The multistage uniform steady flame piece that is used for coal burner of embodiment 2 is seen Fig. 3.Fig. 3 is the steady flame block structure of the coal burner of secondary layout.The arrangement form of front and back stages can be the same or different, and the quantity of layout can be the same or different.The structure of steady flame piece can be the same or different.Wherein one-level is arranged in the outlet of sleeve.
Fig. 4 to Fig. 6 is the structural representation of steady flame piece, and they are respectively the steady flame block structures in rectangle, trapezoidal and curved surface cross section.As seen from the figure, the windward side of steady flame piece can be designed to plane or curved surface, and the shape of lee face also can be designed to plane or curved surface.The shape of described windward side or lee face reaches with the disturbance of the formed angle of each barrel by air to be needed to be provided with.
Sequence number is described as follows among the figure:
The 1-incendiary source; The 2-back-up block; The 3-inner sleeve; 4-urceolus; 5-central tube; 6-steady flame piece.
