Replace your Pyrolitic Torch or Catalytic System
Pyrolytic generation of water vapor is costly, dangerous and limits your maximum growth rate.
The RASIRC Steamer has demonstrate increased growth rate and uniformity by elimination of non-stoichiometric oxygen or hydrogen gas needed to prevent popping in the furnace.
The growth rate of the oxide layer is directly related to the effective diffusion coefficient of the water molecules into the oxide layer and the equilibrium concentration in the immediate area. When excess gas is added to the water vapor, the partial pressure of water vapor is lowered and slows the diffusion of water into the oxide film. The result is lower driving force and slower growth rate.
The RASIRC Steamer generates ultra high purity steam at a constant positive pressure. By eliminating the excess oxygen or hydrogen gas and blanketing the entire furnace tube in pure water vapor, even the loading end of the furnace tube reaches maximum theoretical growth rate.
The RASIRC Steamer eliminates contaminants. The RASIRC Steamer uses a non-porous hydrophilic membrane that selectively allows water vapor to pass. Selectivity is significant with up to 1,000,000x relative to nitrogen molecules. In the vapor phase, the membrane only passes water vapor. All other molecules are greatly restricted, so contaminants in water such as dissolved gases, ions, TOCs, particles, viruses, bacteria, pyrons, and metals can be removed in the steam phase.
