Diffuse combustion method and apparatus

摘要

A method supplies reactants, including fuel gas, to burners that discharge the reactants into a furnace process chamber. 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.

1. A method comprising:
supplying reactants, including fuel and combustion air, to burners that discharge the reactants into a furnace process chamber; projecting stable flames from the burners into the furnace process chamber; and at a time when the furnace process chamber has a temperature at or above an autoignition temperature of the fuel, initiating flameless combustion in the furnace process chamber by supplying a selected burner, of the burners, with additional reactants diverted from a burner, of the burners, other than the selected burner, to blow off the stable flame at the selected burner.
