A system and method are disclosed for lancing gas into an environment, such as a furnace, wherein an inner conduit is in communication with a gas supply and adapted to transport a gas at a first mass flow rate, and an outer conduit is in communication with a gas supply and adapted to transport a gas at a second mass flow rate. The first mass flow rate is greater than the second mass flow rate, preferably at least two times greater. The distal end of the inner conduit is preferably recessed back at a distance from the distal end of the outer conduit.
