Diffuse combustion method and apparatus

摘要

A method supplies reactants, including fuel gas, to burners (116) that discharge the reactants into a furnace process chamber (115). In a stable flame mode of operation, stable flames are projected from the burners into the furnace process chamber. At a time when the furnace process chamber has a temperature at or above an autoignition temperature of the fuel gas, a diffuse combustion mode is initiated by supplying a selected burner with additional reactants, including reactants diverted from another burner, to blow off the stable flame at the selected burner.
