Abstract

PURPOSE:To reduce a loss by overheat at the ignition heater by a method wherein injection holes for injecting gasified fuel are arranged and a part of an outer diameter part of a combustion cylinder for producing flame is bulged out in a sector shape and an ignition heater is arranged at the bulged part. CONSTITUTION:The combustion cylinder 2 injects the gasified fuel forwardly from the injection holes 1. When the fuel is ignited by the ignition heater 5, the fuel may generate a flame and combust. The flame expands fully in the outer diameter part of the combustion cylinder 2 and the heater 5 is located at the part of the bulged portion 4, so that even if the heater 5 is contacted with the large flame diameter, excessive damage may not be found and further since the heater 5 is located at the front part of the bulged portion 4 which is in part bulged out of the outer diameter 3 of the combustion cylinder 2, and therefore a part of the gasified fuel may expand at this part and the ignition may easily be performed.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a combustion tube of a burner, and aims to reduce overheating and burnout of an ignition heater.

For burner combustion tubes used in grain driers, etc.
It is normal to install a heater for ignition in the combustion tube where the combustion action of the fuel ejected while gasifying occurs, but in this configuration, the heater is located within the flame of the combustion tube and is prone to burnout. .

This invention aims to eliminate such defects, and for this purpose, the following technical measures have been taken. That is, a part of the outer diameter part (3) of a combustion cylinder (2) that is provided with a nozzle hole (1) for gasifying and ejecting fuel and emitting a flame is bulged outward in a fan shape, and this bulge is The combustion cylinder of the burner has a structure in which an ignition heater (5) is provided in the part (4).

With this configuration, the present invention has the following technical effects. Immediately, the combustion tube (2) is equipped with an ignition heater (5) to inject gasified fuel forward from the nozzle hole (1).
), it emits a flame and burns. The flame spreads completely inside the outer diameter part (3) of the combustion tube (2), but the heater (
5) is located in this part of the bulging part (4), so even if the heater (5) is in contact with the inside of a large flame, it is less likely to be damaged by overheating. Tube (2)
Because it is located in front of the bulging part (4) that bulges out in a fan shape in a part of the outside diameter AI (3), some of the fuel that has become scum spreads to this part, making it easy to ignite. It is. In addition, if the combustion width is made variable, especially through fuel supply, etc., the size of the flame will change and the temperature of the combustion tube will also change, but the above effect can be achieved at high temperatures, and red flames will not be mixed in as the outside temperature drops. Even if the number of combustion cylinders (
The outer diameter part (3) of 2) is made small so that the flame is enveloped in the center by blowing air, and the temperature in the center is maintained high to prevent the decline in fuel gasification and maintain a wide range of efficient combustion. It is.

46, in the drawing, the combustion tube (2) has an outer diameter part (3) forming an outer peripheral wall, a bottom plate part (8) (9) forming a blowhole (7), a blowhole (]), etc. , installed at the front end of the blower cover (11) that houses the motor 0 [phase], and protruding in the shape of a mountain at the center of the combustion cylinder (2). JQ3 is attached to the shaft 0.1 rotated by the motor 00, and the outer peripheral edge (+4) of the vaporizing cylinder 0 is directed toward the center of the bottom plate (9), so that the gasified fuel 23F can be exuded. 0 yen has 1 fuel sent from pump 00!
With a nozzle that emits 1" S, the inner circumference center G of the vaporization @ θ force is deflected. α7) is a feed

The fuel sent from the pump (lf9) is injected from the tip of the nozzle 0υ into the center of the vaporizer cylinder (12, or the fuel is rotated by the vaporizer r1?l+, i21., J motor 00, The fuel reaches the outer peripheral edge 04) while being diffused along the J plane within 1i' of this carburetor 0 seconds, and during this time, while the air sent through the bifu passes through the carburetor 02), The fuel is turned into scum, and the outer peripheral edge 04) and the bottom plate part (

1) If the flame is ejected from the curve to the front combustion tube (2) and ignited by the heater (5), a flame will be emitted and the flame will fill the outer diameter portion (3) of the combustion tube (2). Expanding, this combustion tube (2
) is sent forward by the wind flowing inside the blower tube (1 [phase]).

The heater (5) protrudes from the front surface of the firing tube (2) close to the outer diameter line (3) of the bulging portion (4).
