Patent ID: 7584905

Claim:
A fuel combustion catalyst delivery apparatus comprising: a storage vessel containing a liquid, the liquid including one or more catalytic materials, the storage vessel including surfaces exposed to the liquid, the surfaces of the storage vessel being inert to the liquid, the storage vessel for coupling to or coupled to a nebulizer, the nebulizer for converting the liquid to an aerosol to be delivered into an intake air of a combustion zone, the aerosol including the one or more catalytic materials, the nebulizer including surfaces for being exposed to the liquid or the aerosol, the surfaces of the nebulizer including a first surface for converting the liquid in contact with the first surface to the aerosol, the first surface for being exposed to the liquid and the aerosol, the surfaces of the nebulizer being inert to the liquid or the aerosol, the surfaces of the first surface being inert to the liquid and the aerosol, the surfaces of the storage vessel, the surfaces of the nebulizer and the first surface capable of maintaining inertness for over 200 hours of operation of the nebulizer or for over 1000 hours of exposure to the liquid or the aerosol, wherein the nebulizer includes a piezoelectric device and wires; the piezoelectric device includes a first surface and electrical contacts; the surfaces of the nebulizer include surfaces of the piezoelectric device, the electrical contacts and the wires; wherein the surfaces of the piezoelectric device, the electrical contacts and the wires are for being exposed to the liquid or the aerosol; the surfaces of the piezoelectric device, the electrical contacts and the wires are inert to the liquid or the aerosol; and wherein the nebulizer further includes a retention chamber containing the piezoelectric device; the piezoelectric device is not mechanically attached to the retention chamber or any other component of the nebulizer; the surfaces of the nebulizer include surfaces of the retention chamber; the surfaces of the retention chamber are for being exposed to the liquid or the aerosol; and the surfaces of the retention chamber are inert to the liquid or the aerosol.
