Abstract
Abstract A method and apparatus for incinerating liquid waste materials. The incinerator of the present invention has a heated combustion bed of aggregate particles contained in a combustion vessel. The vessel is agitated by mechanical means to provide a constant motion to the particles in the bed. The aggregate particles are of relatively large size to eliminate the likelihood of solidification of the aggregate on shut down. Liquid waste materials, which may vary widely in viscosities and may contain widely varying concentrations of solid matter, are introduced into the combustion vessel and incinerated therein. Exhaust means are provided.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
81 words
Apparatus for incineration of liquid waste materials comprising a combustion vessel, a combustion bed of aggregate particles having an average particle size substantially larger than the size of sand, mechanical means for agitating said combustion vessel so as to create a constant motion among said particles of said combustion bed, means for preheating the combustion bed to the combustion temperature, means for introducing liquid waste materials into the combustion vessel, and means for maintaining the combustion bed at said combustion temperature.
Claim 2
Dependent Claim
81 words
Apparatus for incineration of liquid waste materials comprising a combustion vessel, a combustion bed of aggregate particles having an average particle size substantially larger than the size of sand, mechanical means for agitating said combustion vessel so as to create a constant motion among said particles of said combustion bed, means for preheating the combustion bed to the combustion temperature, means for introducing liquid waste materials into the combustion vessel, and means for maintaining the combustion bed at said combustion temperature.
