Abstract
A hybrid burner has a main burner operable with premixing combustion and an auxiliary burner operable with premixing and/or diffusion combustion alone or operable to furnish a pilot light for the main burner. A fitting connects at least one hybrid burner to a main supply apparatus and an auxiliary supply apparatus. The fitting includes a change-over element. A main feed line communicates between the change-over element and the main supply apparatus, an auxiliary feed line communicates between the change-over element and the auxiliary supply apparatus, a main tie line communicates between the change-over element and the main burner and an auxiliary tie line communicates between the change-over element and the auxiliary burner. The change-over element is operable in at least one first and at least one second switching state. In the first switching state the main feed line communicates with the main tie line and the auxiliary feed line communicates with the auxiliary tie line. In the second switching state the main feed line communicates with the auxiliary tie line and the auxiliary feed line is blocked. A switchable throttle element is connected in series with the auxiliary tie line …
