Abstract

Disclosed are a method and an burner apparatus for burning oil and/or gas as fuel. In said method and apparatus, a combined flame (16,3) is generated by means of individual flames (16.1 and 16.2), and a hollow flame is formed within the combined flame, downstream of a fire tube (1) and upstream of the combustion process. In a separate embodiment, exhaust gas can recirculate within said hollow flame. A baffle plate (3) that is disposed inside the air flow is an important structural element for forming the hollow flame.
