Abstract
Abstract An air-curtain incinerator for burning energetic materials. Both the volumef air and the angle at which air enters the fire box are remotely controllable. The combustion process is monitored, and the air volume and angle at which air enters the fire box are controlled to minimize the production of air pollutants by the combustion of energetic materials.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
132 words
An incinerator, comprising; a fire box; blower means for supplying air to said fire box connected thereto; air volume control means connected to said blower means, for controlling the volume of air supplied to said fire box; first monitor means for monitoring the volume of air supplied to said fire box connected to said air volume control means; a manifold connected to said air volume control means for injecting air into said fire box, said manifold having a plurality of nozzles; an air angle control means for controlling the angle at which air enters said fire box connected thereto; second monitor means for monitoring the angle at which air enters said fire box connected to said air angle control means; and third monitor means for monitoring combustion connected to said fire box.
Claim 2
Dependent Claim
132 words
An incinerator, comprising; a fire box; blower means for supplying air to said fire box connected thereto; air volume control means connected to said blower means, for controlling the volume of air supplied to said fire box; first monitor means for monitoring the volume of air supplied to said fire box connected to said air volume control means; a manifold connected to said air volume control means for injecting air into said fire box, said manifold having a plurality of nozzles; an air angle control means for controlling the angle at which air enters said fire box connected thereto; second monitor means for monitoring the angle at which air enters said fire box connected to said air angle control means; and third monitor means for monitoring combustion connected to said fire box.
Claim 3
Dependent Claim
18 words
