    摘要: A gas burner having first flame openings for discharging a stable and self-combustible high-concentration gas and second flame openings for discharging an unstable and non-self-combustible low-concentration gas, with the first and second flame openings being disposed alternately with each other. The effect of stable flame formations at the first flame openings assists stabilization of flame formations at the second flame openings adjacent thereto. Consequently, the gas burner as the whole may have a high air excess ratio to reduce its NOx generation and to prevent incomplete combustion. Further, if a rectifying member is provided in the second flame opening, it becomes possible to enlarge the opening area of the second flame opening without disturbing its flame formation, whereby the burner will achieve further reduction in NOx generation and combustion noise and also improvements in its combustion load and ignition performance.
