Externally mixing flat face burner

摘要

The burner has coaxial ducts for combustion gas and oxidation agent(s). Each inner central tube (7) is centred in the outer ducts (5) of the burner plate (1) by a centring and impingement plate (2) spaced from the burner plate. The centring plate comprises downwards conically widening apertures (6) in the same configuration as in the burner plate. There are lateral gas passage apertures for the oxidation agent inlet from an oxidation chamber (8) into the space (4) between the two plates (1,2).
