Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a burner, and is used as a burner for drying grains, etc. If the burner is configured to send combustion heat forward by strong ventilation around the outer periphery of the combustion tube in the center where the combustion flame is generated, a portion of the ventilation will flow into the front of the combustion tube in a spiral shape and generate the combustion flame. Disturbing the flame will inhibit the spread of the flame.

The present invention has taken the following technical measures to eliminate such defects. That is, a vaporizing cylinder 1 that vaporizes fuel by rotation, and a combustion disk 2 located on the outer periphery of this vaporizing cylinder 1 that spouts forward the vaporized fuel sent from this vaporizing cylinder 1 are located in the center, and the combustion flame is directed forward. A heater 4 for igniting the vaporized fuel ejected from the combustion disk 2 is provided on one side of the combustion tube 3 that guides diffusion into the combustion tube 3, and the upper and lower parts of the combustion tube 3 except for the heater 4 on the rear side are equipped with heaters 4. The burner is provided with diffusion plates 5 and 6 that protrude outward from the outer peripheral edge of the combustion tube 3 and provide resistance to air blowing.

With this configuration, the present invention has the following technical effects. That is, while the fuel passes through the rotating vaporizing cylinder 1, it is vaporized and ejected forward from the combustion disk 2, ignited by the heater 4 and burned, and the combustion flame is spread across the front surface of the combustion cylinder 3.
It is sent forward by the air flowing forward around the outer periphery of the combustion tube 3, and the air flowing around the outer periphery of the combustion tube 3 is resisted by the upper and lower diffusion plates 5, 6. The combustion flame spreads easily in the upper and lower parts, and the heater 4 of the combustion tube 3 provided on one side is located in the part where this combustion flame does not easily spread, making it difficult to overheat. This prevents the fuel from becoming oil droplets on the lower end side of the fuel cell 3, making it easier to achieve complete combustion.

In the illustrated example, the vaporizing tube 1 has a conical shape, and its center portion is fixed to the rotating shaft 7. Inside the vaporizing tube 1, a blowing guide tube 9 at the tip of the blowing cylinder 8 is positioned. An ejection chamber 10 on the back side of the combustion disk 2 is provided at the outer circumferential end of the vaporization passage between the outer circumference surface of the combustion chamber 1 and the outer circumference surface of the vaporization cylinder 1, and an ejection hole 11 is provided in the combustion disk 2. The combustion tube 3 has a cylinder wall facing forward on the outer periphery of the combustion disk 2. A heater 4 is provided near one side of the peripheral wall of the combustion tube 3, and the combustion disk is connected from the peripheral wall on the opposite side. 2. A frame sensor 12 is provided to protrude toward the front surface. Reference numeral 13 denotes a fuel nozzle, which is projected into the tip of the guide tube 9. The resistance plates 5 and 6 are provided over appropriate widths on the upper and lower sides of the blower tube 8, and their outer edges are appropriately extended outward from the outer peripheral edge of the combustion tube 3.

When the rotation shaft 7 rotates the vaporization tube 1 and fuel is supplied from the nozzle 13, it is vaporized as it travels through the vaporization tube 1 to the ejection chamber 10 of the combustion disk 2, and is ejected forward from the ejection hole 11. The vaporized fuel is ignited and burned by the heater, and the flame is sent forward at the front of the combustion tube 3 by the air around the outer periphery. As a result, the blowing force is weakened, so the flame spreads in the vertical direction, and the heater 4 and flame sensor 12 on both left and right sides generate strong air blowing close to the outer peripheral surface of the combustion tube 3, causing the flame to spread outward. It's difficult.
