Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
27 words
The process of oxidative disposal of a liquid waste stream according to claim 1 wherein said oxidation catalyst is one of the group containing Pt and Pd.
Claim 2
Dependent Claim
96 words
Apparatus for oxidative disposal of a liquid waste stream made up primarily of organic materials diluted with water comprising, in combination, a furnace chamber provided with a combustion burner and a vaporous product exhaust port, a liquid waste stream introduction nozzle disposed substantially coaxial with said combustion burner and in opposition thereto, said nozzle distributing said liquid waste stream predominantly as a frustoconical envelope of liquid droplets substantially enclosing the flame of said combustion bUrner, means introducing air into said furnace chamber, and oxidation catalyst means in series flow circuit with said vaporous products exhaust port.
Claim 3
Dependent Claim
32 words
Apparatus for oxidative disposal of a liquid waste stream according to claim 3 wherein said combustion burner is of a type functioning with a range of 0-1500 percent excess air or more.
Claim 4
Dependent Claim
29 words
Apparatus for oxidative disposal of a liquid waste stream according to claim 3 provided with means controlling the fuel supply responsive to the sensed temperature in said exhaust port.
