The PyreTron™ patented burner uses independently controlled streams of gas, air and oxygen to overcome the conventional limitations of oxygen use. It produces a flame with high temperature, luminosity and velocity, increasing both radiative and convective heat transfer.
This is accomplished by using an oxygen staged combustion approach which accelerates fuel pyrolysis inside an extremely hot flame core, contained in a specially structured flame envelope.
In the first combustion stage, the fuel is mixed with a sub-stoichiometric amount of pure oxygen inside the central portion of the flame, creating a fuel rich flame core, in which the fuel is partially combusted and pyrolyzed.
This pyrolysis of fuel in the flame core creates a cloud of micro particles of carbon and hydrocarbon radicals of extremely high emissivity and temperature, due to the complete elimination of nitrogen inside the flame core. The second oxidizer, usually air or oxygen-enriched air, is introduced in the second combustion stage, the fuel lean zone, to complete the combustion reaction in the final combustion zone.
By combining oxy-fuel and air flame, flue gas heat losses are reduced while available heat and productivity are increased:
