Abstract
A burner with a burner head (B) and a flame tube (F) is provided, with the burner head (B) having a concentric outlet arrangement of air and fuel feed nozzles. Following this a mixture of low-nitrogen air and fuel is produced, which is ignited in a chamber (11) in the interior of a hollow body (20). Hard-to-burn, noncombusted gas compounds flow upon exiting from the hollow body (20) along the exterior surface thereof back into the region before the hollow body (20) and flow again together with low-nitrogen air into the chamber (11) for combustion. This additional combustion increases the energy yield of the fuel and reduces the quantity of pollutants in the exhaust.
