Incinerator for unsegregated refuse

Claim 1

An incinerator for the treatment of unsegregated refuse containing organic matter, comprising a. an injecting chamber for refuse, b. a rotary distributor at the bottom of said injecting chamber for even distribution of said refuse, c. an annular drying chamber for drying the refuse received from said rotary distributor, d. an annular dry distilling chamber for pretreating, heat cracking and dry distilling the refuse from the annular drying chamber, e. an annular oxidizing chamber including blow nozzle means for introducing a gasifying agent containing one-third to onefourth of the quantity of air sufficient for complete combustion of said refuse, f. these annular chambers communicating in sequential arrangement from top downwardly so that the gas generated in these chambers rises upwardly, g. a gas duct having a gas collecting branch communicating with said annular drying chamber to collect and lead out from said annular chambers gases generated within same, said generated gases including corrosive and toxic components, h. a residue reservoir communicating with said annular oxidizing chamber and including a flame chamber having a downwardly directed, axially located first burner therein, i. a secondary incinerating chamber below said rEsidue reservoir and having a second burner therein, j. a port connecting the bottom of said residue reservoir with said secondary incinerating chamber, k. a water cooling chamber communicating with the bottom of said secondary incinerating chamber, l. and further ducting connecting said gas duct with said first burner and said second burner, whereby, in use, said generated gases are collected by said gas duct and utilized as the heat source for said flame chamber and said secondary incinerating chamber.

Claim 10

A method of treatment of unsegregated refuse containing a substantial portion of organic matter, comprising the steps of introducing said refuse into an incinerator through a port proximate the top thereof, passing said refuse in downward direction sequentially over a rotary distributor, thence through an annular dry-distillation chamber, thence through an annular oxidizing chamber below said dry-distillation chamber, introducing steam and hot air into said oxidizing chamber where the quantity of air introduced is from one-fourth to one-third that necessary for combustion of said residue, hot gases being generated in said annular chambers, passing said refuse from said oxizing chamber through a residue reservoir chamber below said oxidizing chamber, said residue reservoir chamber being supplied with hot gaseous combustion products which bring about partial melting of said refuse to a residue, passing said partially molten residue through a port into an incineration chamber below said residue reservoir chamber, and introducing said hot gases with added air into said first and second burners to complete the combustion of said residue, thereby making the incineration of said refuse substantially self-sustaining.

Claim 11

A method of treatment of unsegregated refuse containing a substantial portion of organic matter, comprising the steps of introducing said refuse into an incinerator through a port proximate the top thereof, passing said refuse in downward direction sequentially over a rotary distributor, thence through an annular dry-distillation chamber, thence through an annular oxidizing chamber below said dry-distillation chamber, introducing steam and hot air into said oxidizing chamber where the quantity of air introduced is from one-fourth to one-third that necessary for combustion of said residue, hot gases being generated in said annular chambers, passing said refuse from said oxizing chamber through a residue reservoir chamber below said oxidizing chamber, said residue reservoir chamber being supplied with hot gaseous combustion products which bring about partial melting of said refuse to a residue, passing said partially molten residue through a port into an incineration chamber below said residue reservoir chamber, and introducing said hot gases with added air into said first and second burners to complete the combustion of said residue, thereby making the incineration of said refuse substantially self-sustaining.
