Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
111 words
In an incinerator, a cylindrical housing of refractory material, a feed duct leading tangentially into said housing, a burner mounted in said housing adjacent said duct, a partition in said housing forming a narrow annular primary burning chamber and an axial secondary chamber, means for introducing waste and air into said burning chamber through said feed duct at a point adjacent the upper end of said primary burning chamber, said burner being mounted to discharge into said primary chamber in a direction substantially parallel to said duct, a baffle in said primary chamber disposed therein so that the combustion product produces a turbulent flue stream by transversing the annular primary chamber.
Claim 2
Dependent Claim
