Heating industrial oven using burner involves reaction zone with pre-reaction zone in mixing and combustion chamber associated with burner nozzles and setting ratio of pulse flow densities of oxidant to fuel flow to between 0.45 and 10

摘要

The method involves using a burner to which a gaseous oxidant and a fuel are fed that react to form a reaction zone. A fuel flow emanates via a central burner nozzle (13) and an oxidant flow visa an annular burner nozzle (14) around the central nozzle. The reaction zone contains a pre-reaction zone in a mixing and combustion chamber associated with the burner nozzles and the ratio of pulse flow densities of the oxidant flow to fuel flow is set to a value between 0.45 and 10. An independent claim is also included for a pipe-in-pipe burner.
