A burner (10) equipped with a main combustion unit (20), which burns a premixed gas in which a fuel gas and air have been mixed with a first air-fuel ratio, and multiple flame stabilization units (30), which are arranged so as to sandwich therebetween the main combustion unit (20), and which burn a premixed gas at a second air-fuel ratio that is lower than the first air-fuel ratio, and enables stable flame formation. |
