Abstract
A method for combustion in an industrial furnace having fuel and a first oxidizer to heat a material includes arranging at least one lance in a sidewall of the furnace; supplying a second oxidizer with an oxygen content of at least 85 percent by weight in the form of a jet traveling at at least sonic velocity to the interior of the furnace through the at least one lance; running the jet of the second oxidizer in the horizontal plane above the material between and essentially in parallel with two consecutive rows of the roof burners; balancing an amount of the second oxidizer supplied per time unit so that the oxygen content supplied via the second oxidizer constitutes at least 50 percent by weight of the total supplied oxygen per time unit in the furnace.
