Premixed combustion gas burner having separated fire hole units
A premixed combustion gas burner having separated fire hole units including a tube-shaped burner whose front face is opened and inner portion is of a hollow tubular shape so that the whole fire hole units of the burner can be separated to thus prevent deformation due to thermal expansion, in which fire hole units each having a number of fire holes formed at a predetermined distance from one another are disposed in both edge lines and the inner portion on the upper end face, and loaders each having a predetermined space are formed between the fire hole units; and a plate-shaped burner which is made of a plate-shaped material having a pin structure formed on the bottom thereof so as to be mounted on the loaders formed in the tube-shaped burner, in which fire hole units having a number of fire holes formed at a predetermined distance are disposed in the form of a slit along both the edge lines of the upper end face. Here, the number of fire holes forming the fire hole units of the tube-shaped burner and the plate-shaped burner are formed with a uniform size by a press, and a cooling water tube is disposed to penetrate the fire holes through fitting holes formed on the lateral surface of the tube-shaped burner and fitting holes formed on the pin-structure formed on the bottom of the plate-shaped burner, in correspondence to the fitting holes of the tube-shaped burner.
1. A premixed combustion gas burner having separated fire hole units comprising:
a tube-shaped burner having an opened front face and a hollow tubular shaped inner portion wherein the whole fire hole units of the burner can be separated to prevent deformation due to thermal expansion, the fire hole units, each having a number of fire holes formed at a predetermined distance from one another, disposed in both edge lines and an inner portion on an upper end face, and loaders, each having a predetermined space, formed between the fire hole units; and
a plate-shaped burner made of a plate-shaped material having a pin structure formed on a bottom thereof so as to be mounted on the loaders formed in the tube-shaped burner, the fire hole units, having a number of fire holes formed at a predetermined distance, are disposed in the form of a slit along both the edge lines of the upper end face.
2. The premixed combustion gas burner of claim 1 , wherein the number of fire holes forming the fire hole units of the tube-shaped burner and the plate-shaped burner are formed with a uniform size by a press.
3. The premixed combustion gas burner of claim 1 , wherein a cooling water tube is disposed to penetrate the fire holes through fitting holes formed on a lateral surface of the tube-shaped burner and fitting holes formed on the pin-structure formed on the bottom of the plate-shaped burner, in correspondence to the fitting holes of the tube-shaped burner.
