PURPOSE:To prevent generation of CO and combustion noise caused by clogging of dust etc. in air suction ports, by forming a combustion chamber of box type of an inner and an outer combustion walls, and the air and fuel necessary for combustion are fed into the chamber and by conducting full secondary combustion in an outer combustion chamber through small holes. CONSTITUTION:A combustion chamber 15 is monolithically formed into box type of an inside wall 10, made of U-shaped heat-resistant steel sheet, provided with a plurality of small holes 9, an outside combustion wall 13, made of heat-resistant steel sheet, provided with middle sized holes 11 in the red-heated wall part A and with small holes 12 in the lower part, both being assembled in an integrated body. An inside wall 21, made of heat-resistant steel sheet, is installed at the back of an internal combustion wall 10, and the top plate 22 of the inside wall is combined with a combustion wall 16. An outside wall 24, made of heat-resistant steel sheet, which is joined with a heat-resistant, permeable material, such as a heat-resistant glass 23, is provided to the front part of an outer combustion wall 13. By composing a burner in such a manner, radiation to one direction only can be obtained, and generation of CO and combustion noise caused by clogging in suction ports of the primary air due to dust and the like, are prevented, while a gas stove requiring small installation space is available by making the burner in a thin type. |
