Abstract
Abstract A high efficiency domestic furnace incorporates means for separating and neutralizing flue gas condensate. Acidic condensate from the flue gas products of combustion is neutralized by contact with neutralizing material in a housing through which the condensate is flowed. The use of the neutralizer in connection with a high efficiency domestic furnace permits discharge of the condensate directly to the household drain. The neutralizer is arranged to be self-flushing and defines a serpentine, series flow path and is arranged to discharge the neutralized condensate as a result of the entry of additional acidic condensate at its inlet. To enhance the operation of the neutralizer, it is arranged to be vibrated during normal operation of the furnace.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
105 words
In a domestic furnace having means for burning fuel resultingly producing gaseous products of combustion having water vapor therein, and means for exhausting said gaseous products of combustion, the improvement comprising: separating means associated with said exhaust means for converting said water vapor to a liquid condensate and removing said condensate from said products of combustion; conducting means for conducting said condensate from said separating means; condensate treatment means for receiving said condensate from said conducting means and reducing the acidity thereof; and means for imparting mechanical movement to said condensate treatment means during the operation of said furnace to maintain the neutralizing effectiveness thereof.
Claim 2
Dependent Claim
105 words
In a domestic furnace having means for burning fuel resultingly producing gaseous products of combustion having water vapor therein, and means for exhausting said gaseous products of combustion, the improvement comprising: separating means associated with said exhaust means for converting said water vapor to a liquid condensate and removing said condensate from said products of combustion; conducting means for conducting said condensate from said separating means; condensate treatment means for receiving said condensate from said conducting means and reducing the acidity thereof; and means for imparting mechanical movement to said condensate treatment means during the operation of said furnace to maintain the neutralizing effectiveness thereof.
Claim 3
Dependent Claim
22 words
The domestic furnace structure of claim 1 wherein said means for imparting mechanical movement comprises means for vibrating said condensate treatment means.
Claim 4
Dependent Claim
23 words
The domestic furnace structure of claim 1 wherein said means for imparting mechanical movement is energized substantially concurrently with said fuel burning means.
Claim 5
Dependent Claim
25 words
The domestic furnace structure of claim 1 wherein said means for imparting mechanical movement comprises an electro-mechanical component normally energized during operation of said furnace.
Claim 6
Dependent Claim
98 words
In a domestic furnace having means for burning fuel resultingly producing gaseous products of combustion, and exhaust passage means for exhausting the gaseous products of combustion free of addition of water vapor thereto, the improvement comprising: condensate treatment means arranged to receive condensate from said exhaust passage means which may result from a low temperature condition of said products of combustion in said passage means including a housing containing a neutralizing material for contacting condensate delivered to said housing; and means for vibrating said housing for at least a portion of the time said burner is in operation.
Claim 7
Dependent Claim
98 words
In a domestic furnace having means for burning fuel resultingly producing gaseous products of combustion, and exhaust passage means for exhausting the gaseous products of combustion free of addition of water vapor thereto, the improvement comprising: condensate treatment means arranged to receive condensate from said exhaust passage means which may result from a low temperature condition of said products of combustion in said passage means including a housing containing a neutralizing material for contacting condensate delivered to said housing; and means for vibrating said housing for at least a portion of the time said burner is in operation.
Claim 8
Dependent Claim
40 words
The domestic furnace structure of claim 5 wherein said furnace includes a blower and said condensate treatment housing is mechanically coupled to said blower such that said housing is vibrated by said blower during periods when said blower is operating.
Claim 9
Dependent Claim
105 words
In a domestic furnace having a burner, a heat exchanger for receiving gaseous products of combustion from said burner, exhaust means for receiving products of combustion from said heat exchanger, condensate treatment means disposed in spaced relationship to said exhaust means, and passage means connected to said exhaust means and arranged to conduct condensate therefrom to said treatment means for treatment of the condensate, the improvement comprising: a source of vibration that is energized during periods when said burner is operating; and means coupling said source of vibration to said condensate treatment means to vibrate said treatment means for maintaining effectiveness of the treatment means.
Claim 10
Dependent Claim
105 words
In a domestic furnace having a burner, a heat exchanger for receiving gaseous products of combustion from said burner, exhaust means for receiving products of combustion from said heat exchanger, condensate treatment means disposed in spaced relationship to said exhaust means, and passage means connected to said exhaust means and arranged to conduct condensate therefrom to said treatment means for treatment of the condensate, the improvement comprising: a source of vibration that is energized during periods when said burner is operating; and means coupling said source of vibration to said condensate treatment means to vibrate said treatment means for maintaining effectiveness of the treatment means.
Claim 11
Dependent Claim
37 words
The furnace structure of claim 7 wherein said condensate treatment means includes a housing defining a condensate flow path therethrough and particles of condensate treating material are contained within at least a portion of said flow path.
Claim 12
Dependent Claim
21 words
The furnace structure of claim 7 wherein said source of vibration comprises a blower for circulating air through said heat exchanger.
Claim 13
Dependent Claim
23 words
The furnace structure of claim 9 wherein said blower includes an external housing and said condensate treatment means is mounted to said housing.
Claim 14
Dependent Claim
14 words
The furnace structure of claim 7 wherein said passage means comprises a flexible conduit.
