The second hollow tube body 1〇4 is provided with a first hollow tube body 102 and is disposed coaxially with the first hollow tube body to define an annular chamber chamber as shown in FIGS. 3A and 3B. It is shown that the clock of the second hollow pipe body is larger than the radius of the first hollow pipe body 1 () 2 . Wherein, the second hollow tube body has two inlet ends 104a and an outlet end lion, and has a blade, a group 112 adjacent to the outlet end 104b of the second hollow tube body, and the blade group 112 is from the second The wall of the hollow tubular body extends radially outward. Here, the above-mentioned blade may be inclined at an angle ' with respect to the axial direction a', that is, an atbach angle, or a material and a radial inclination angle', that is, a twist angle. As shown in FIG. 3A and FIG. 3B, the hollow cylindrical cylinder 1〇6 is provided with a second hollow tubular body 1〇4 and disposed coaxially with the second hollow tubular body 104 to define a ring shape=1〇. The radius of the empty cylinder 106 is greater than the radius of the second hollow tubular body. (4) The main cylinder 106 has an inlet end leg and a plurality of outlet ends, and the outlet end 106b is looped on the hollow cylinder wall. The opening. The third hollow pipe body 108 is connected with a hollow cylinder and is coaxial with the hollow cylinder. 设置6 is set to define an annular cavity m, wherein the radius of the third hollow pipe body iQ8 is larger than the radius of the hollow cylinder 106 And the third hollow tube body (10) has an inlet end and an outlet end 108b. The combustion chamber 110 is disposed at the outlet end of the first hollow tubular body 1 2, the second hollow tubular body 8 1 574 824 and the second hollow tubular body 〇 8 , and communicates with the first hollow tubular body 1 〇 2 'the first hollow tube body 104 and the third hollow tube body 1 〇 8. As shown in Fig. 2, the first hollow tube body 1〇2, the second hollow tube body 1〇4, the hollow cylinder tube 106, the third hollow tube body 1〇8, and the combustion chamber 11〇 are assembled. The structure is not intended to be 'where the first hollow tube body is withdrawn, the second hollow tube body is smooth, the hollow cylinder tube 106 and the second hollow tube body 1〇8 are provided with a plurality of screws 13 螺, nuts (3) And the thread, etc. _ 妓 mutual secret transfer, and the lock is fixed. From this, it can be seen that the first hollow tube body 102, the second hollow tube body temple, the hollow cylindrical tube ship, and the third hollow tube body (10) are detachable type elements. In addition, the front-funded type is not limited to the use of threaded screwing, but also can be used to facilitate the (four) bolt-to-the hollow tube body 102 and the second hollow tube body, while the hollow cylinder tube hits the third The hollow tube body (10) is fixed by welding. Please refer to FIG. 3A and FIG. B, respectively, which are schematic cross-sectional structures of the plane of the stereo disk of FIG. Referring to FIG. 3A and FIG. 3β, the chamber of the first hollow tube 102 is configured to receive a main fuel, and the outlet end of the first hollow tube is disposed in the combustion chamber 11 The combustion chamber is connected to one end and the main fuel is injected into the combustion chamber 11〇. The annular tube of the second hollow tube body is used to receive a main air, and the outlet end leg of the second hollow tube body is set at the end of the combustion chamber m - 11Q, _ county Air is injected into the combustion chamber no. Therefore, when the splitter main _ and the main air are in the first middle body 102 and the second middle _, the contact main air is slowly mixed in the combustion (four), and the concentration of the main fuel and the main air reaches the combustion equivalent. Production ratio (eq_le job tree will produce - diffusion flame. Therefore, the diffusion fire ^ fire 9 ^ length is longer, its radiation is higher. Continue to refer to Figures 3A and 3B, the hollow cylinder 106 The annular chamber C is for receiving the secondary fuel, and the annular chamber of the third hollow tubular body 108 is for receiving the secondary air, and the outlet end 108b of the third hollow tubular body 108 is S is further in the middle of the U0 and is connected to the combustion chamber 110. The above-mentioned main fuel or field material is, for example, a heavy oil, a diesel oil, a low calorific biomass synthetic oil. The main air or the secondary air is, for example, a low calorific value syngas belonging to a gas, a blast furnace gas, a converter gas, a low calorific value, and the like, but is not limited thereto. Referring to FIG. 3A and FIG. 4 simultaneously, A narrow section 140 is defined between the wall of the three hollow tubular body and the wall of the cylinder of the middle cylinder 106, and the hollow cylinder 1 is The outlet of the crucible 6 is connected and the 106b is connected to the narrow section 14〇, and the expansion section 15〇 is defined between the wall of the third hollow tubular body 1〇8 and the wall of the second hollow tubular body 104, and the expansion section 150 is opposite The narrow section 14〇 is disposed at the downstream. In other words, the annular chamber of the third hollow tube body is divided into a narrow section 140 and an expanded section 150, and the narrow section 140 is adjacent to the expanded section 15〇 for the ring. A difference is formed in the chamber 108c, and the step design is a backstep design. As shown in FIG. 3A, the blade group 112 extends radially to the second hollow tube 104 and the third. Between the hollow tubes 108 and the ring is disposed at the outlet end 10b of the third hollow tube 108. Therefore, when the secondary fuel and the secondary air are separately injected into the hollow cylinder 1〇6 and the third hollow tube At body 108, the secondary fuel will flow through the outlet end 1〇6b of the hollow cylinder 1〇6 to the narrow section 140′ of the second hollow body 108 and then mix with the q air in the third hollow body. When the mixed gas enters the expansion section I% from the narrow section 140, due to the thirst phenomenon caused by the difference of the structure, the mixed gas will first perform the first 1374883 Once mixed, the mixed gas flows through the blade group 112, and a second mixing is performed, and then injected into the combustion chamber 110 for combustion. Thus, the secondary fuel and the secondary air can be pre-combusted before combustion. After uniformly mixing, the combustion is further performed to generate a premixed flame, wherein when the mixed gas flows through the blade group 112, the angle of attack or the torsion angle of the blade group can be transmitted, so that the mixed body can be fully mixed. In other words, by the design of the blade group's attack domain twisting, the gas flowing therethrough generates a strong swirling flow for uniform mixing. In addition, the burner 100 further includes an igniter that communicates with the combustion chamber 110. 12〇, used to carry out the combustion reaction. Wherein, the igniter 120 is in a degree of presentation with the combustion chamber. The sensed state 122 is used to sense the flame generated in the combustion chamber, and the sensor interface is phased and woven, for example, riding an external line side (1; ¥ detector). Alternatively, the burner 100 may be provided with a flow control width (not shown) to control the flow of the primary/secondary fuel and the primary/secondary air. Alternatively, the burner 1 can be provided with an observation hole 124 for observing the flame generated in the combustion chamber 11〇.
