Description of the Invention: [Technical Field of the Invention] [0001] The present invention relates mainly to a primary and secondary burner used in a gas furnace. [Prior Art] [0002] Conventionally, such a primary and secondary burner is composed of the following: a secondary burner comprising: a secondary burner body; a secondary burner cover placed on the secondary combustion II body, and a secondary combustion a mixed gas chamber is drawn between the zones; and a plurality of secondary burner flame holes are formed in the circumferential direction of the sub-burner cover; and the main burner comprises: an annular main burner body surrounding the pair Burner body; ring record: the age cover cover 'the rest of the main _ _, on the area between the main combustion body to draw a mixed gas room; and the direction = Lin Ji, the coffee touches across the square [ 0003] Flame hole i main burning =, generally, a spark hole is opened in the upper wall portion of the sub-burner cover by a spark plug, and the inner portion is extended from the upper inner side: the outer peripheral side of the cover is burned (refer to For example, in the above-mentioned example, the slit flame hole crosses the entire length of the main burner 4 201245638 mixed gas chamber. Since the mixed gas from the middle portion of the slit flame hole is obtained from the slit flame hole, the discharge flow rate of the mixed gas to the outer end portion is small. In the case of the present invention, the problem is to be solved. [Patent Document 1] [Patent Document 1] JP-A-2005-164058 (Invention) [0006] In the above anecdote, the present invention can provide a one-year-old autumn yarn to improve the performance of the burn-in. The method of solving the problem is the method of solving the problem. [0007] Qian Shuzhu, the present invention is a kind of main and auxiliary burner, which is composed of a main combustion state of a sizzling disc, the sub-burner comprising: a street burner, a > a sub-burner body; a hood cover placed on the sub-burner body The mixed gas chamber is taken out between the areas; and you/, the main body of the multi-burning flame hole is formed by the sub-sounding sound, and the heart is covered by the wall. The heart is separated by the circumference of the main combustion. The utility model comprises: a nuclear main burner body surrounding the sub-burner. The body burner body is woven with the main burner, and the main side and the burner are separated by a square side. : 5 201245638 Warp hole, which is narrower from the inner peripheral side of the upper wall The radial direction of the flame hole is extended between the flame holes of the main burner, and the surface of the flame is filled into the phase of the machine. 11 years old under the room. [0008] The body chamber is directly connected to the mixture. The mixed gas is reduced, and as a result, the flame generated from the outer end of the aperture is changed: [in the case of a plus. Therefore, in the slit flame [0009], the heart is difficult, and the burning performance is improved. And in the present invention, Preferably, the portion of the main flame that is ignited in the groove-shaped flame portion is formed on the lower surface of the lower wall, and the mixture gas flowing from the lower surface of the upper wall of the corresponding cover is ejected along the main burner cover, and the burning performance is introduced into the component from the slit. Radial outer end portion of the flame hole [0010] The circumferential surface is formed with the inner peripheral portion of the outer peripheral side of the cover, and the radially outer end portion of the projection is inserted into the recessed gap of the two recesses. The radially outer end portion of the slit flame hole 俾 communicates with the radial direction of the gas [0011] = gap", and can be prevented from being excessively discharged due to the flow between the concave portions. The flow rate of the main squirting, I 乂 is the cover lift or the yellow flame 201245638 is burnt poorly. [0012] The gas flows from the radial ends of the groove-shaped flame hole into the lower part: according to this 'mixed flame hole The jet stream of the mixed gas ejected by the part J: Prevents a small and continuous flame, and prevents the slit flame from being part of [0013] in the slit flame shape __ wheel micro' [Embodiment] [0015] Reference 8Π 2 is a 'burner of the embodiment of the present invention' from the sub-combustor i and surrounding the sub-combustor! =, the device contains a burner mixing tube U and the main burner is mixed with H, from the face of each nozzle (not The gas mixture from the mouth is produced in the mixing tubes η, 2i with the mixed gas of the artificial enthalpy. The two mixing tubes 11, 21 are partially passed through the downstream side - _ .u .R v Belonging to the downstream side portion of the sub-combustor mixing tube η, upward 丄 = Ua, and the downstream side of the main ugly H mixing tube 21, toward ^ 1 H tube 21a is composed of inner and outer 2 heavy cylinders. ^歼卜【0017】, and the main and auxiliary burners include: .. sub-burner body 12, fitting inner cylinder ua upper end; and annular main burner The main body 22 surrounds the sub-combustor body 12. The main burner body 22 smashes the upper end portion of the outer cylinder 21a, and is guided to the main burner body 2, the portion 22a and the sub-burner via the mixed gas of the future autonomous burner 201245638 The main body 12 is formed. [0018] The sub-burner cover 13 is placed on the sub-burner body 12, and the sub-manufacturer body 12 and the sub-burner 'cover 13 are attached to the door. Out::t,1 to the sub-burner flame hole u. The mixed gas chamber between the dry tray 13 is separated from the sub-burner [0019] ^ The body 22 is placed on the annular main burner cover μ, The main combustion hood cover 23, the tti 22 and the main burner cover 23 constitute the outer peripheral side peripheral wall portion 23a of the main burner, and the circumference of the main burner flame portion 24, in this case, the number of main burner flame holes 24. The main ^ direction is separated to form a large-diameter channel melon and the main combustion! The mixed gas of the tube 21 is self-ignited via the mixed gas chamber ii= The area between the 2242g burner cover 23 is drawn [0020], so that ==, ===/, by means of the cover 23 can be relative to the main combustion body. The vertical wall 22e 'main combustion [0021] And the main and auxiliary burners are provided: Mars plug 3, facing the main burner cover 23; and 'with thermocouple 4 gamma burner / = age 2 toward the sub-combustion cover, burning 112 , the main burner 8 201245638 side by side 3 into 25, the remaining tank paste - material, the direction of the 接近 close to the slit? hole 26, from the central extension of the flame hole 25 toward the radial outward, the autonomous burner flame hole 24 toward the slit flame The hole is 26% odor, and the flame hole 25 is burned. The hole is burned. The state of the burn is cut toward the state of the main burner 2, and the self-squeezing device is burned. ζFrom ^1f勒焰孔Η The flame hole 24 is burned. The slit flame hole 26 faces the main burner [0023] When the outer periphery of the cover 23 is applied to the main burner chamber, the mixture is burned from the slit, and the mixed gas ί H6 radially outer end portion 26a or radially ^Mixed ΐί f ί ^Slit, the slit flame hole 26 has a small amount of mixed gas at the radially inner end. That is, the hole 25 is burned between the sub-burner flame hole 14 and ==, and there is a significant problem in that the radial outer end of the slit flame hole 26 is wide. If the discharge flow rate of the fire body generated in the radially outer end portion 26a is small, the injection child, the im'tree money burner view here, in the present embodiment, for example, the intermediate portion is formed to face the main burner 2 The mixed gas; the slit flame hole 26 is a groove-shaped flame hole portion 26b. And in the main _ crying =, to the lower part of the surface closed to the outer end - 28, 俾 方 ^ ^ 201245638 to the gap 28b. Further, a slit flame hole 2 radial gap 28b is formed. And in the main burning crying cover j shouting 2 such as '俾 connect the part of the slit flame hole 26, shape & cover ^ upper decoration 23c upper surface outer peripheral kiss [0027] $ Cheng Chao search outwards to the lower slope The corner portion 29. The depth of the upper projection 27 other than the projection 27 is smaller than the outer peripheral side wall portion 23a of the outer peripheral side. Further, the recessed portion is formed in a portion of the slit flame hole 26 radially outward, and a portion of the flame hole 24, the shape 24a, and the small flame hole 24b located at the center in the circumferential direction of the slit flame hole %. Further, the large-flame hole recessed portion 28c on both sides of the concave portion 28 is formed as a slit flame hole. The directional = outward is more concave - the grade 28c extends radially outward. Rainbow is smashing outwards.卩26a, 俾 from the depressed portion [0028] successively, the main combustion; If the groove-shaped flame portion 26b of the intermediate portion is not directly discharged, the flow rate is reduced, and the self-sewed flame hole 26 is used to spray the mixed gas between the portions. The flow rate increases. And the "combined gas" along the main "outer end portion 26a" of the "Kunming gas" due to the protrusion 27 flows toward the lower surface of the radially outer disk ^ 23c has a direction toward the radial direction of the outer side of the red eight 1 ^ £ | b + square /, inside The party is ~. Therefore, the mixed gas is discharged from the radially outer end portion 26a: AHm6 j through the outer end portion 26a to the end portion 2, and the heat is merged with each other to form a circumference between the two 28 and the protrusion η. The square flows radially outward. Therefore, there may be a gap between the 27 gaps 28b to the radially outer end of the hole 26 adjacent to the slit flame of the self-connecting radial gap 28b, and the component in the direction of the direction, 2=]b and the slit The flame hole formed by the thin a portion between the flame holes 26 is again 'moved through the outer wall of the main burner body 22, and the protrusion π radial 201245638 = the radial outer end of the mixture 26 in the up and down direction between the ends The portion 26a is ejected, but the second self-hole is again from the radially outer end of the slit flame hole 26 = the majority of the body is purely between the concave portion 28 and the projection 27 117^^: I?!: !—^ 1, ^ 旦 , " ^ Γ / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / The bottom of the groove is deeper than the lower surface of the upper wall portion 23e other than the projection 27, and (4) [0032] The burn-out property between the outer end portions 26a also becomes good. The narrowness _ 妒 ii 26 continues to widen the portion of the outer end portion 26a and widens the side of the flame portion. As a result, a large amount of the burnt flame iL portion 26a' is ejected, and the main burner flame hole ΓΪ5ί' is formed as shown in Fig. 5, and the wide flame hole portion 26a, ‘Z. The kernel may have a shape in which the widened flame hole portion 26a' is a circular hole shape. For example, the present invention is limited to the embodiment, but the present invention is not in the above-mentioned (four), and is on the outer peripheral side of the main burner cover 23. 201245638 The portion of the anastomosis concave portion 28 is shaped to extend the flame holes 24a, 24b, but the side circumferential direction is narrow and narrow 'between the forming portions of the adjacent concave portion 28, that is, the main burner flame hole 24 and the slit flame hole % From the 27th, the radial direction is outside: 2: body: time outside: can form a sudden [schematic description] [0014] Figure 1 is a schematic diagram of the main and auxiliary burners of the embodiment of the present invention A cross-sectional view of the burner.
