Abstract
Abstract An incinerator generally including a combustion chamber, a flue, means for conducting combustion gases emanating from the combustion chamber to the flue, the conducting means including passage means for imparting a curved motion to the combustion gases, means disposed in the passage means for producing a plurality of electrostatic fields including a plurality of sets of spaced electrodes, each set of electrodes producing an electrostatic field through which a portion of the gases traverse, and means disposed either upstream relative to the means for producing a plurality of electrostatic fields, or in conjunction therewith, for ionizing the combustion gases, whereby contaminants including solids and gaseous molecules entrained in the combustion gases will be ionized by the ionizing means and subjected to cooperating centrifugal, electrostatic and gravitational forces as the gases traverse through the passage means to remove the contaminants from the combustion gases.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
111 words
An apparatus for removing contaminants entrained in a stream of gas comprising means for imparting a curved motion to said stream of gas, means for producing a plurality of electrostatic fields including a plurality of sets of spaced electrodes, each set of electrodes producing an electrostatic field through which a portion of said gases traverse, means disposed upstream relative to said means for producing a plurality of electrostatic fields, for ionizing said gases whereby contaminants entrained in said combustion gases will be ionized by said ionizing means and subjected to cooperating centrifugal, electrostatic and gravitational forces as said stream of gases flows through said apparatus, and means for collecting said contaminants.
Claim 2
Independent Claim
111 words
An apparatus for removing contaminants entrained in a stream of gas comprising means for imparting a curved motion to said stream of gas, means for producing a plurality of electrostatic fields including a plurality of sets of spaced electrodes, each set of electrodes producing an electrostatic field through which a portion of said gases traverse, means disposed upstream relative to said means for producing a plurality of electrostatic fields, for ionizing said gases whereby contaminants entrained in said combustion gases will be ionized by said ionizing means and subjected to cooperating centrifugal, electrostatic and gravitational forces as said stream of gases flows through said apparatus, and means for collecting said contaminants.
Claim 3
Dependent Claim
24 words
An apparatus for removing contaminants entrained in a stream of gas according to Claim 1 including means for removing contaminants deposited on said electrodes.
Claim 4
Dependent Claim
40 words
An apparatus for removing contaminants entrained in a stream of gas according to claim 2 wherein said means for removing contaminants deposited on said electrodes comprises means for injecting a fluid on said electrodes to wash the deposited contaminants therefrom.
Claim 5
Dependent Claim
54 words
An apparatus for removing contaminants entrained in a stream of gas according to claim 1 wherein the electrodes of each of said set of electrodes comprise elongated plates disposed sufficiently adjacent along the lengths thereof to provide an electrostatic field having sufficient strength to precipitate ionized contaminants entrained in said gas stream traversing therethrough.
Claim 6
Dependent Claim
23 words
An apparatus for removing contaminants entrained in a stream of gas according to claim 1 wherein said electrodes consist of spaced, rectilinear plates.
Claim 7
Dependent Claim
23 words
An apparatus for removing contaminants entrained in a stream of gases according to claim 1 wherein said electrodes consist of spaced, curved plates.
Claim 8
Dependent Claim
29 words
An apparatus for removing contaminants entrained in a stream of gas according to claim 1 wherein said electrodes consist of spaced, curved plates having substantially tangential trailing end portions.
Claim 9
Dependent Claim
44 words
An apparatus for removing contaminants entrained in a stream of gas according to claim 1 wherein said means for imparting a curved motion to said stream of gases functions to cause said stream of gases to follow a curved path about a horizontal axis.
Claim 10
Dependent Claim
93 words
An apparatus for removing contaminants entrained in a stream of gas according to claim 1 wherein said means for imparting a curved motion to said stream of gases comprises a curved passageway having a horizontal axis of curvature, said electrodes are curved and substantially parallel having a substantially horizontal axis of curvature, said electrodes are mounted on traversely disposed support members secured to opposite sidewalls of said passageway, having adjacent electrodes of opposite polarity insulated from each other, and means for injecting a washing fluid on the electrodes on which contaminants are deposited.
