A burner of the air adjustment type using a liquid fuel includes a fuel chamber including a bottom wall, a peripheral side wall and at least one fuel gas opening on the top surface portion of the fuel chamber and a burner proper including a fuel chamber attachment, an inner gas chamber and a plurality of final gas openings arranged and distributed annularly on the ceiling wall of the gas chamber. The burner proper further includes variable air openings connected to the gas chamber, wherein an annular variable air passage surrounding the fuel chamber and being connected to the variable air openings at a position lower than the position of the fuel gas opening is formed between the inner face of the peripheral side wall of the gas chamber of the burner proper and the outer face of the peripheral side wall of the fuel chamber. The fuel gas opening, the final gas openings and the annular variable air passage are arranged in such a positional relationship that when the variable air openings are opened, a variable combustion layer is formed in the gas chamber between a fuel gas stream extended from the fuel gas opening to the final gas openings and a variable air stream on the periphery of a fuel gas stream connected to the variable air openings. |

DETAILED DESCRIPTION Methyl alcohol can easily be synthesized from various raw materials such as natural gas, petroleum, solid carbon, petroleum pitch and the like, and it is liquid in the normal state and is completely burnt at relatively low temperatures.
Further, by combustion, methyl alcohol is converted to an odorless gas consisting solely of H.
sub.
2 O and CO.
sub.
2.
In view of easy availability, easiness in handling, prevention of environmental pollution and low manufacturing cost, methyl alcohol is apparently one of the promising fuels.
Therefore, it is desirable to develop a burner such as a range in which methyl alcohol is used as a fuel and the foregoing defects involved in the conventional alcohol ranges are overcome or moderated.
It is therefore a primary object of the present invention to provide a burner of the air adjustment type using a liquid fuel, especially methyl alcohol, in which by simple means of changing the amount of air flown into the burner, multi-staged adjustment of the heating power in a broad region can be accomplished.
Another object of the present invention is to provide a burner of the air adjustment type in which the maximum heating power is uniformly maintained at a level sufficiently applicable to ordinary cooking and the like throughout the burning operation, namely at ignition, during normal combustion and just before exhaustion of the fuel and incomplete combustion is effectively prevented in any stage of the burning operation.
Still another object of the present invention is to provide a burner of the air adjustment type in which the heating power can be adjusted promptly and precisely in follow-up of the change of the amount of supplied air, namely the time lag in the adjustment of the heating power is remarkably shortened.
A further object of the present invention is to provide a burner of the air adjustment type in which occurrence of undulation or intermission of flames caused in the above-mentioned conventional burners of the air adjustment type, namely occurrence of a phenomenon that flames are disturbed and rendered unstable when completely closed air openings are opened or the air openings are kept in the slightly opened state, can be effectively prevented
