## Abstract

A high cuisine burner capable of establishing a high heating power or temperature with a low combustion noise and adjusting the heating power easily. The burner comprises: an inner mixing tube for mixing combustible gas and air; a gas head fitted on the upper end of the inner mixing tube and having a plurality of inner flame holes; an air inlet tube arranged concentrically outside of the inner mixing tube and having a plurality of outer flame holes in the circumference of the upper end thereof; a device for blowing additional air into the air inlet tube; a gas head tube fixed on the outer side of the upper end portion of the air inlet tube; and an outer mixing tube extending from the gas head tube for mixing further combustible gas and air, whereby the additional air fed from the air inlet tube is blown between the outer flame holes and the inner flame holes. The burner may further comprise a flame hole cap fastened in the upper end of the gas head tube and having the plurality of outer flame holes.

## Claims

### Claim 1

A burner for feeding a mixture of combustible gas and combustion air from an inner mixing tube to a gas head so as to inject the mixture of gases from a plurality of flame holes of the gas head, comprising:
said inner mixing tube, with an upper end, for mixing combustible gas and combustible air;
said gas head being fitted on the upper end of said inner mixing tube and having said plurality of inner flame holes;
an air inlet tube, with a upper end and an outer side, arranged concentrically outside of said inner mixing tube and having a plurality of outer flame holes in the circumference of the upper end thereof;
means for blowing additional air into said air inlet tube, whereby the additional air fed from said air inlet tube is blown between said outer flame holes and said inner flame holes;
a gas head tube fixed on the outer side of the upper end portion of said air inlet tube; and
an outer mixing tube extending from said gas head tube for mixing further combustion gas and further combustion air.

### Claim 2

A burner for feeding a mixture of combustible gas and combustion air from an inner mixing tube to a gas head to inject the mixture of gasses from a plurality of flame holes of the gas head, comprising:
said inner mixing tube, with an upper end, for mixing combustible gas and combustible air;
said gas head being fitted on the upper end of said inner mixing tube and having a plurality of inner flame holes;
an air inlet tube, with a upper end and an outer side, arranged concentrically outside of said inner mixing tube;
means for blowing additional air into said air inlet tube;
a gas head tube, with an upper end, fitted on the outer side of the upper end portion of said air inlet tube;
an outer mixing tube extending from said gas head tube for mixing further combustible gas and combustible air; and
a flame hole cap fastened on the upper end of said gas head tube and having a plurality of outer flame holes, whereby the additional air fed from said air inlet tube is blown between said outer flame holes and said inner flame holes.
