US Patent:

51037424, Apr 14, 1992

Filed:

Feb 6, 1991

Appl. No.:

7/651656

Inventors:

Joseph V. Valentino - White Plains NY

International Classification:

F23J 1500

US Classification:

110215

Abstract:

An exhaust system adapted for the selective control of the types and concentrations of emissions to the atmosphere in the off-gas of a combustion unit, the system including at least one chemical treatment chamber, at least one off-gas, kinetic energy reducing chamber communicating with at least one chemical treatment chamber and adapted to provide a reduced pressure off-gas region wherein the kinetic energy of the off-gas from the treatment chamber is diminished, at least one chemical reactor communicating with at least one treatment chamber and adapted to provide reactant chemicals in contact with the off-gas in the treatment chamber, at least one reactant chemical selecting system associated with at least one chemical reactor and adapted for presenting different chemicals and concentrations thereof to the off-gas in at least one treatment chamber, cooling apparatus for the off-gas in one or more selected portions of the exhaust system, and a control system communicating with the off-gas at one or more locations within the exhaust system for qualitatively and quantitatively analyzing the off-gas and actuating the selecting system in relationship to the gas analysis to provide selected reactant chemicals in predetermined quantities to at least one chemical reactor for contact with the off-gas to selectively control the types and concentrations of matter therein.

Filed:

Dec 18, 1991

Appl. No.:

7/809884

Inventors:

Joseph V. Valentino - White Plains NY

International Classification:

F23J 1500
B01D 5334

US Classification:

423210

Abstract:

An integrated, at least substantially self-contained and at least substantially closed-loop combustion process and system for the control of gaseous, ionic, colloidal, liquid or particulate matter, particularly noxious contaminants contained in the off-gas of a combustion unit, the system comprising a: (a) chemical treatment chamber; (b) a reactant source communicating with the treatment chamber and adapted to provide reactant chemicals in contact with the off-gas; (c) a reactant chemical selector associated with the reactant source; (d) a control device communicating with the off-gas within the combustion system for analyzing the off-gas and actuating the selector in response to the analysis to provide reactant chemicals for contact with the off-gas; (e) an expansion chamber communicating with the treatment chamber and adapted to provide a reduced pressure region of treated off-gas received from the treatment chamber means; (f) an exhaust port in the expansion chamber for discharging the off-gas, and (g) cooling means for cooling the off-gas in one or more locations within the combustion system.

Appl. No.:

8/662794

Inventors:

Joseph V. Valentino - White Plains NY

International Classification:

B01D 5334

US Classification:

422177

Abstract:

A substantially closed-loop system for use with a furnace wherein a fuel is burned and produces an off-gas, which system, by sensing appropriate parameters of the off-gas as it passes through the system, treats that off-gas in an optimized fashion in order to substantially eliminate the escape of contaminants and produce a substantial amount of useful by-products by one or more of (a) controlled treatment of the off-gas chemically and physically by employing a multi-flue compartmented and appropriately controlled treatment means, (b) the subsequent conversion of the essentially gaseous effluent from that treatment means into useful by-products, and (c) the subsequent conversion of the essentially non-gaseous effluent from the treatment chamber into useful by-products.
