And a gas burner in which 24 secondary air discharge holes 13 each having a diameter of 6 mm and upper and lower auxiliary air discharge holes 4 each having a diameter of 6 mm were formed. Then, the position of each auxiliary air discharge hole 14 was made coincident with the gas mixture air outlet 12, and the gas mixture was supplied and burned using a blower 19 having a maximum air volume of 3.0 m 3 / min and a maximum static pressure of 50 mmAg. . As a result, the position of the auxiliary air discharge hole 14 is changed to the gas mixture jet 1
Compared to the case where the gas burner is displaced from 2, the combustion noise of the gas burner of the present invention is reduced by about 30%. When the measurement was performed with the block 7 installed, the combustion noise was further reduced. When the height of the block 7 is higher than the upper edge of the lower secondary air discharge hole 13b, the flame lifts, and when the height of the block 7 is lower than the lower edge of the lower secondary air discharge hole 13b. The flame turned yellow. Therefore, the height of the block 7 is preferably lower than the upper edge of the lower secondary air discharge hole 13b and higher than the lower edge of the lower secondary air discharge hole 13b.
