Description

[Detailed description of the invention] This invention increases the height of the combustion flame of a white-yellow flame combustor, obtains combustion flames of uniform height, and also obtains a medium-wide variable range of combustion amount. It is.

In conventional white-yellow flame combustors, the upper end of the combustion flame is The heights of the flames were extremely uneven, and the lower flame height areas in particular gave the impression that incomplete combustion was occurring more than in reality compared to other areas. For this reason, making the combustion flame large gives an unfavorable impression when the heights are uneven, so measures are taken to make the combustion flame smaller so that the unevenness is not noticeable. The amount of heat was reduced, and the performance when used as a stove was expected to deteriorate. This invention is intended to prevent the above-mentioned drawbacks, and is capable of supplying a large amount of air at a slow speed to petroleum vapor or petroleum combustible gas in a linear or annular combustor that burns petroleum with a white-yellow flame. An air rectifying cover 3 is provided sandwiching the combustion wick 1 or combustible cylinder 2 provided, and a plurality of flame tubes 4 are arranged in succession on the upper part of the air rectifying cover 3.
The height of the main core 1' is made higher than the part directly below the flame pulp 4.

In addition, in the embodiment, the combustion wick 1 has a main wick 0 1' and an auxiliary wick r.
The height of the auxiliary core 1'' is higher than the highest part of the main core 1'. In the figure, 5 is an oil tank, 6 is a core vertical axis, and 7 is a core reader. When the upper and lower wicks 6 rotate, the combustion wick 1 inside the core blade skin cylinder 7 moves up and down.As a white-yellow flame combustor, air is guided to the upper end of the combustion wick 1 by an air rectifying cover 3. Even if it is a type in which the petroleum vapor vaporized from the combustion wick 1 is directly combusted by carrying out a fuel cell, the combustion wick 1 is protruded into the gap between the combustion cylinders 3 made up of perforated plates, and the oil obtained by performing primary combustion. Air rectifier cover 3 to combustible gas
The petroleum combustible gas may be combusted with a white-yellow flame by supplying air which is transferred by 3' is an upper air rectifying cover, and a fresh air inlet 8 is raised between it and the lower air rectifying cover 3.

9 is a communication hole on the top air rectifying cover,
The list corresponds to a plurality of flame cylinders 4.

This type of white-yellow flame combustor sucks combustion air by the draft generated inside the flame tube and supplies it to petroleum vapor or petroleum combustible gas. The cylinder becomes thicker, and local draft fluctuations and local resistance changes in the combustion air supply path directly affect combustion, and the oil vaporized from the combustion wick does not burn directly above the combustion wick, causing a strong draft. This appears as variations in the height of the combustion flame.

However, in this invention, since a plurality of flame tubes 4 are arranged in succession on the upper part of the air rectifying cover 3, the flame tubes 4 become thin and long.

For this reason, there is almost no difference in the draft generated between each flame tube 4, and since this draft acts directly on the combustion wick 1 directly below, the oil vaporized from the combustion wick 1 is always guided to the flame tube 4 directly above. It is something that In particular, a region where the draft is extremely weak is created between the flame tubes 4, so even if the combustion wicks 1 are continuous, the oil vaporized from the combustion wick 1 cannot be seen with the naked eye. It acts as a partition and prevents petroleum gas from flowing into the flame tube 4 other than directly above.

As described above, there is almost no difference in the draft of the flame tubes 4, and there is also almost no difference in the amount of oil and gas supplied per flame tube 4, so the height of the combustion flames formed is also almost the same. The uneven height of the combustion flame can now be completely prevented.

If the uneven height of the combustion flame no longer occurs, it becomes possible to supply air in stages to increase the height of the combustion flame, and a large amount of heat rays can be emitted from the large combustion flame, making it an excellent feature as a heater. was gotten. On the other hand, the linear or annular combustion wick 1 is formed by a main wick 1' and an auxiliary wick 1'' in close contact with each other, and the height of the main wick 1' is uneven so that the part directly below the flame tube 4 is higher. , the amount of oil that vaporizes from the main core 1' increases directly below the flame tube 4, that is, in the convex portion of the main core 1', and conversely, between the flame node 4 and the flame tube 4, it vaporizes in the concave portion. Since the amount of oil is small, even when the combustion wick 1 is raised high, oil gas will not flow into the flame tubes 4 other than directly above, and the variation in the amount of oil gas flowing into each flame tube 4 will be due to the combustion wick 1. Even when it's high, it's almost gone.

Therefore, even if the height of the combustion wick 1 is changed by rotating the wick vertical axis 6, the amount of oil gas flowing into each flame tube 4 can vary over a wide range regardless of the position of the combustion wick 1 according to the wick vertical axis 6. There was no variation across the board. Furthermore, when the combustion wick 1 is in the wick storage tube 7, the oil has also soaked into the auxiliary wick 1'', and during ignition, the ignition flame passes through the auxiliary wick r rather than the main wick 1' and spreads to the entire combustion wick 1. Therefore, even if there are irregularities on the main wick 1', the flame transfer is completed in a short time and combustion is started.Furthermore, once combustion has started, the volume of the combustion wick protruding from the wick housing tube 7 is: Even if the height of the auxiliary wick 1'' is higher than the main wick 1' and is constant, it changes according to the unevenness of the main wick 1', and the height of the auxiliary wick 1'' changes according to the unevenness of the main wick 1'. There is still a large amount of oil vaporized directly below the area.

Therefore, even if the main core 1' is uneven, excellent fire transfer performance can be obtained.
