This patent describes a method of heating a furnace with a gas burner located adjacent to a furnace wall, to provide a reduced percentage of nitrogen oxide components in the furnace flue gas. It comprises burning a mixture of primary gaseous fuel and primary air in the furnace; guiding the products of combustion to form a combustion gas screen directed generally along a portion of the furnace wall adjacent to the burner; introducing a separate flow of secondary gaseous fuel in a path also directed toward the area along the portion of the furnace wall; and introducing secondary air along the burner, whereby the secondary air is contacted by and at least partially mixed with the combustion gas stream as the secondary air moves into position to react with the secondary gaseous fuel.
