Pyretron, a Variable Gas/Oxygen/Air Combustion System

This paper presents the engineering principles behind a new variable gas/oxygen/air combustion method called PYRETRONtm. The Pyretron increases flame luminosity and velocity by using oxygen to accelerate the pyrolysis of natural gas inside an extremely hot flame core contained in a specially structured and controllable flame envelope. In addition, the system provides increased controllability of the chemical inputs to provide for an excess hot oxidizer when needed for refining or to reduce the oxidation ability of combustion products when they will negatively impact product quality. These advances have application in the melting of copper, steel and aluminum, in the forging and rolling of steel where the process is sensitive to combustion products and in processes such as the melting of glass and the heating of ceramic products where both the product and the furnace are sensitive to uneven temperature distribution. The paper specifically illustrates the operating advances of the Pyretron from experience gained in steel making applications.
