ーナ。[Claims for Utility Model Registration] 1. An independent burner body with a structure that can independently adjust the primary air ratio at a constant differential pressure by using two types of burners: a main burner that supplies a lean mixture and an auxiliary burner that supplies a rich mixture. A combination of main and sub-burners is arranged in any desired number in parallel, and a secondary air inlet is provided between the main burners or between the main and sub-burners, and the The amount of fuel gas supplied to the main burner and auxiliary burner is 70 to 80%: 3
0 to 20%, and the air ratio of the mixture supplied to the main burner and sub burner to be 1.4 to 2, respectively.
．． 0 and 0.67 to 0.5, and the average air ratio of the entire burner is adjusted to be in the range of 1.2 to 1.7. 2. The semi-Bunsen type gas burner according to claim 1, characterized in that a flame stabilizing wall is provided around the flame opening of the auxiliary burner to improve flame stability of the auxiliary burner. 3. The semi-Bunsen gas burner according to claim 1, wherein the secondary air inlet is located above the flame ports of the main and sub burners. 4. The semi-Bunsen type gas burner according to claim 1, wherein the flame opening slits of the main burner and the flame opening slits of the auxiliary burner are provided so as to be orthogonal to each other.
