Abstract
A multi-stage exhaust apparatus to reduce the emission of pollutants from a fossil fuel furnace and to achieve greater efficiency in the energy consumption by such furnace. The multi-stage exhaust may include a vacuum chamber boiler, a submerged pump vacuum chamber, a bath scrubber, and a clean air tower. The system may further include a secondary submerged vacuum chamber and a secondary bath scrubber.
Claims16
A vacuum chamber boiler comprising:
- an elongate body having a sidewall defining a cavity therein,
- a sealing plate extending across said cavity and sealingly engaging with an interior surface of said sidewall to define a boiler chamber in a lower portion of said cavity and a vacuum chamber in an upper portion of said cavity;
- and
- a smokestack substantially contained within said boiler chamber and extending from a first opening at bottom of said boiler chamber to a second opening in said sealing plate, said smokestack adapted to communicate exhausts received from a furnace through said first opening and said second opening, said second opening in communication with said vacuum chamber;
- wherein said boiler is adapted to receive a source of liquid for producing steam, and the vacuum chamber is adapted to receive a vacuum source applied to an outlet of said vacuum chamber.

A bath scrubber comprising:
- a main chamber defined by an outer wall of said bath scrubber;
- said main chamber having a lower portion adapted to contain a volume of a of chemical water bath to a fill line of said main chamber and an upper portion defined above said fill line;
- an inlet defined in said lower portion adapted to receive exhausts from fossil fuel combustion contained in a furnace;
- a perforated plate extending across the lateral and longitudinal aspects of said main chamber beneath said fill line;
- and
- an outlet defined in said upper portion adapted to evacuate said exhausts from said bath scrubber.

An apparatus for cleaning flue gas, comprising:
- a vacuum chamber boiler comprising:
- an elongate body having a sidewall defining a cavity therein,
- a sealing plate extending across said cavity and sealingly engaging with an interior surface of said sidewall to define a boiler chamber in a lower portion of said cavity and a vacuum chamber in an upper portion of said cavity;
- and
- a smokestack substantially contained within said boiler chamber and extending from a first opening at bottom of said boiler chamber to a second opening in said sealing plate, said smokestack adapted to communicate exhausts received from a furnace through said first opening and said second opening, said second opening in communication with said vacuum chamber;
- wherein said boiler is adapted to receive a source of liquid for producing steam, and the vacuum chamber is adapted to receive a vacuum source applied to an outlet of said vacuum chamber;
- a bath scrubber comprising:
- a main chamber defined by an outer wall of said bath scrubber, said main chamber having a lower portion adapted to contain a volume of a of chemical water bath to a fill line of said main chamber and an upper portion defined above said fill line;
- an inlet defined in said lower portion adapted to receive exhausts from fossil fuel combustion contained in a furnace;
- a perforated plate extending across the lateral and longitudinal aspects of said main chamber beneath said fill line;
- and
- a vacuum outlet defined in said upper portion and connected to a vacuum source;
- wherein said vacuum source comprises a vacuum pump, connected to said vacuum chamber outlet via a conduit, wherein said vacuum pump is submerged in a circulating source of cooling fluid contained within a vacuum station external to said vacuum chamber boiler.
