JPS584A - Combustion cylinder of oil burner - Google Patents

Abstract

PURPOSE:To enable perfect secondary combustion, in the titled combustion cylinder of an oil burner of the system in which combustion air is supplied to the flame spreading device through the clearance between the flame cylinder and the heat rays transmission cylinder, by making the flame cylinder larger in diameter than the heat rays transmission cylinder. CONSTITUTION:The heat transmission flame cylinder 7 provided on the outside of the secondary combustion chamber A is made larger in diameter than the heat transmission cylinder 5, being installed vertically on the non-heat transmission cylinder 4. The air to be supplied outside the flame spreading device 6 is fed through the clearance B between the flame cylinder 7 and the heat transmission cylinder 5. With this system, therefore, combustion air is introduced from the bottom of the combustion cylinder to be supplied outside the flame spreading device 6 passing through a long passage. This long air passage helps alleviate the effects of a sudden change in disturbances, such as a blast hitting the combustion cylinder, before combustion air reaches outside the flame spreading device 6, with the result that secondary combustion flame is prevented from flickering and that generation of smoke, carbon monoxide and hydrocarbon gas is almost completely suppressed.

Description

Detailed Description of the Invention This invention not only improves combustion performance, but also positions the center of gravity of the combustion tube downward, so that even if the combustion tube is tilted during normal ignition operations, it can easily return to its original position. In other words, as shown in the figure which is an embodiment, an outer cylinder 3 is provided on the outside of the inner flame cylinder 1 and the outer flame cylinder 2, and the outer cylinder 3 is located at the lower part. It consists of an opaque cylinder 4 and a heat ray transparent cylinder 5 at the upper part, and heat rays are radiated outward from the upper part of the red-hot outer flame cylinder 2, and a flame contact device 6 is installed above the inner flame cylinder 1. At the same time, the combustion air is supplied to the flame contact device 6 through the inside of the inner flame tube 1, and all fresh air is supplied to the outside of the flame contact device 6 to perform secondary combustion. The heat ray transmitting flame tube 7 on the outside of the combustion chamber A has a larger diameter than the heat ray transmitting tube 5 and is installed upright from the opaque tube 4, and allows air to flow from the gap B between the heat ray transmitting tube 5 and the flame tube 7 to the flame contacting device 6. This relates to the combustion tube of an oil combustor that is supplied with Reference numeral 8 denotes an air hole in the non-transparent cylinder 4, which supplies all the air to the WMB.

Further, 9 is a partition plate of the secondary combustion chamber A, and 1 tlB of air is sent from below the partition plate 9 to the flame expansion plate 6.It is a central cylinder installed inside the 10-piece inner flame cylinder 1, and is in contact with the flame. Air is supplied to the inside of the device 6.

] 1 is the core inner cylinder, 12 is the core outer cylinder, 13 is the core, and the core] 3
protrudes into the gap C between the inner and outer flame tubes 1 and 2, and the inner and outer flame tubes].2 are mounted on the core and inner and outer flame tubes 1].12. 1
4 is a flange of the core outer cylinder 12, which looks into the lower part of the impermeable cylinder 4. Since the structure is as described above, the primary combustion is carried out in the combustion section composed of the inner and outer flame cylinders 1 and 2 and the outer cylinder 3. During combustion, the upper part of the outer flame cylinder 2 becomes completely red hot and radiates heat rays to the outside.When the amount of oil vaporized is large, such as by increasing the amount of protrusion of the wick 3, complete combustion is performed only by the primary combustion, and the internal combustion is not completed. - The combustion gas coming out of the outer flame tubes 1 and 2 contains a large amount of unburned gas (incomplete combustion gas). Six flame contact devices installed above the inner flame @1 burn unburned gas, and combustion air is supplied from inside the inner flame tube 1. Inner Flame Cylinder] A large amount of unburned gas cannot be combusted with only internal combustion air, and fresh air must be supplied from outside the flame contact device 6.

In this invention, the flame WJ7 outside the secondary combustion chamber A is transferred to the heat transmitting tube 5.
It has a larger diameter and is set upright from the opaque tube 4, and the air to be supplied to the outside of the flame contact device 6 is supplied from the gap B between the flame tube 9 and the heat transmitting tube 5. The air is supplied from the air holes 8 of 4.

For this reason, combustion air is taken in from the lower part of the combustion tube and passes through a long flow path before being supplied to the outside of the flame contact device 6, so sudden changes in disturbance conditions such as strong wind blowing into the combustion tube can occur. Even if it occurs, the long flow path interferes and reaches the outside of the flame contact device 6. At 1, the sudden change stops and the fluctuation becomes gradual.

Therefore, it was possible to prevent the secondary combustion flame from dancing, and the generation of oil smoke, carbon monoxide, and hydrocarbon gas was almost eliminated.

Also, since the flame tube 7 is positioned not only outside the secondary combustion chamber A but also outside the outer tube 3, the center of gravity of the flame tube 7 is lowered, and the center of gravity of the flame tube 7 is lower. Since the outer diameter of the supporting opaque cylinder 4 is 100cm wide, the angle of inclination of the combustion cylinder is reduced when one side of the combustion cylinder is fully lifted during ignition operation and when the tip of the wick 13 is ignited with a flame or ignition heater. Due in part to the low center of gravity of the cylinder, the amount of wobbling when the combustion cylinder was returned to its original position was kept very small despite the tall combustion cylinder.

As described above, according to the structure of this invention, secondary combustion is very incomplete combustion. Therefore, it is possible to obtain a combustion tube that fulfills the original purpose of performing secondary combustion of the incompletely combusted gas generated by secondary combustion and thereby achieving complete combustion. The ease of ignition has also been improved to the extent that it can be compared with conventional combustion tubes, despite the heavy combustion sludge, and the practical performance has been significantly improved.
