Abstract

PURPOSE:To carry out rapid vaporization by a method wherein an intermediate cylinder constituted into one body with a vaporization cylinder and installed therein is placed and a fuel supply device and an air blower are installed so that fuel charged into the vaporization cylinder together with combustion air is forced to collide with the vaporization cylinder nearly at right angles. CONSTITUTION:When a vaporization cylinder 14 is heated to a specified temp. by power supply to a heater 13, a fuel pump 25 and an air blasting fan 27 are operated and liquid fuel is supplied into the cylinder 14 from a fuel tank 26 through a fuel nozzle 24 and a part of combustion air is delivered into the cylinder 14 from an air nozzle 23 as primary air. Scattered fuel particles are instantly vaporized at the bottom or the side wall of the cylinder 14 to be formed into a mixture after being mixed with the primary air. The mixture is introduced by a mixture guide 19 in being mixed uniformly with a mixing plate 18 and then ejected from a cylindrical burner head 20 and ignited with an ignitor and combustion is carried out forming inward flames.

In the above configuration, when the vaporization cylinder 1 is heated by the heater 2 and primary air and liquid fuel are supplied into the vaporization cylinder 1 from the primary air nozzle 11 and the fuel nozzle 12, the fuel is transferred to the heated inner wall of the vaporization cylinder 1. The gas collides obliquely with the air, vaporizes while moving along the inner wall, mixes with the primary air, becomes an air-fuel mixture, exits through the first flame port 4 and the second flame port 6, and burns.

Problems to be Solved by the Invention However, in the above-mentioned conventional example, since the liquid fuel obliquely collides with the inner wall of the vaporization cylinder together with the air from the primary air nozzle, the splitting and diffusion of fuel particles on the wall surface is small, and The combustion lees and particles were accelerated by the air flow and vaporized while floating on the surface of the water, as if they were pebbles thrown, and the disadvantage was that the vaporization rate was slow. Furthermore, if the temperature of the vaporization cylinder is a little high, there is a problem in that the fuel just slides on the inner wall and no vaporization occurs at all.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides an intermediate cylinder that is integrated with the vaporizer cylinder within the vaporizer cylinder, and a liquid that is sent into the vaporizer cylinder together with the combustion air. A fuel supply device and a blower device are provided so that the fuel collides with the middle cylinder almost perpendicularly.

In the above configuration, the heater 13 is energized and the vaporizer cylinder 14
When the fuel is heated to a predetermined temperature, the fuel pump 25 and the blower fan 27 are activated, and the fuel is discharged from the fuel tank 26 to the fuel nozzle 2.
4, liquid fuel is supplied into the vaporization cylinder 14, and part of the combustion air is supplied to the air nozzle 23 as primary air.
It enters the vaporizer cylinder 14. The liquid fuel that has entered the vaporization tube 14 is accelerated by the primary air flow, collides almost perpendicularly with the middle tube 15 and splits, and is scattered in the vaporization tube 14 as small droplets. At this time, the velocity of the primary airflow is reduced by the collision with the middle cylinder 15, so the flow does not accelerate the fuel particles, but instead flows slowly into the middle cylinder 15.
It plays the role of transporting fuel particles to the rear side of the fuel cell 5 and expanding the vaporization area. The fuel particles scattered in this way are
It vaporizes instantaneously at the bottom and side walls of the air tank 4, and mixes with the primary air to form an air-fuel mixture. The air-fuel mixture is uniformly mixed by the mixing plate 1, and then exclusively by the air-fuel mixture guide 19, and is ejected from the cylindrical burner head 20 to the igniter (
(not shown), and combustion occurs while forming an inward flame. The burner head 20 is composed of a flame-holding tube 21 having a large number of small holes and a flame-holding net 22 tightly wrapped inside the flame-holding tube. On the other hand, from the blower fan 27, the blowing fan 27 was adjusted on day #9.
A part of it is supplied to the middle cylinder 15 which is erected integrally with the bottom of the vaporizing cylinder 14, and the rest is supplied to the outer cylinder 29. The combustion air that has entered the middle cylinder 15 is ejected through the center air port 16 in the axial direction of the shibana head 20, but is converted into secondary air at an angle to the flame from the burner head 20 by the diffusion plate 17 disposed above. Supplied. Furthermore, the combustion air supplied into the outer cylinder 29 is transferred to the burner head 20.
The outer peripheral air port 3 is opened as a ring-shaped gap near the top end.
The secondary air is ejected in the radial direction from zero and is supplied almost perpendicularly to the flame extending from the burner head 20.

In this way, secondary air is supplied to the combustion flame in the burner head &9 from both the inside and outside, so that complete combustion occurs and the flame length is shortened. In addition, since combustion heat is recovered to the carburetor cylinder 14 by heating the middle cylinder by flame, the middle cylinder 15 becomes hotter than other parts of the vaporizer cylinder 14, and fuel collision and fragmentation do not occur. There are also simple effects. That is, while the high-temperature wall surface of the middle cylinder 15 promotes the splitting and scattering of the colliding fuel and prevents tar adhesion on the collision surface, the fuel can be instantaneously vaporized by the slightly low-temperature vaporization cylinder wall of the middle cylinder. can.

Effects of the Invention As is clear from the above explanation, according to the vaporizer of the present invention, the liquid fuel collides with the combustion air almost perpendicularly to the middle cylinder installed in the vaporizer cylinder, and the splitting occurs. The latter fuel particles are dispersed over a wide area of the side wall and bottom of the carburetor cylinder, and in order to avoid being excessively accelerated by the airflow, the fuel particles have sufficient contact with the inner surface of the carburetor cylinder, resulting in rapid vaporization. effective.
