Air curtain incinerator

1. A method of incinerating waste comprising the steps of:

providing a firebox, at least one fuel-burning burner unit for directing a flame into the firebox, and air curtain means for providing a sheet of high velocity air flow over a top opening of the firebox;

loading the firebox with waste;

activating the at least one burner unit until waste combustion is sustainable without energy from the at least one burner unit, and then deactivating the at least one burner unit to allow waste combustion to proceed on its own;

activating the air curtain means;

monitoring particulate release from the waste combustion;

reactivating the at least one burner unit if particulate release rises above an acceptable range, and then deactivating the at least one burner unit when particulate release is in the acceptable range.

2. The method according to claim 1 , wherein the step of monitoring particulate release is performed visually using the Ringlemann smoke scale.

3. The method according to claim 1 , wherein the step of monitoring particulate release is performed by one or more opacity sensors.

4. An incinerator apparatus comprising:

a frame, wherein the frame includes front and rear opposite ends, a pair of spaced skids extending from the front end to the rear end for contacting the ground, and a tow coupling at the front end;

a firebox supported on the frame, the firebox including an open top and a plurality of walls defining a combustion chamber;

a fuel supply tank supported on the frame;

a fuel-burning generator supported on the frame in communication with the fuel supply tank, the generator supplying electric power;

a fuel-burning burner unit in communication with the fuel supply tank, the burner unit being arranged to direct a flame into the combustion chamber; and

air curtain means supported on the frame and powered by the generator for providing a sheet of high velocity air flow generally across the open top of the firebox; and

a control room adjacent the firebox, wherein the fuel supply tank and the generator are housed in the control room.

5. The apparatus according to claim 4 , wherein the control room is proximate to the front end of the frame.

6. The apparatus according to claim 4 , further comprising an automatic fuel injector regulating flow of fuel to the burner unit and a controller connected to the fuel injector, whereby output intensity of the burner unit is adjustable by the controller.

7. The apparatus according to claim 6 , further comprising at least one sensor connected to the controller for providing feedback to the controller for automatically adjusting the output intensity of the burner unit.

8. The apparatus according to claim 7 , wherein the at least one sensor includes a temperature sensor measuring temperature in the firebox.

9. The apparatus according to claim 7 , wherein the at least one sensor includes an opacity sensor measuring the opacity of smoke from combustion of the waste material.

10. The apparatus according to claim 6 , wherein the controller is housed in the control room.

11. The apparatus according to claim 10 , further comprising an operator interface in the control room in communication with the controller for enabling an operator to enter commands to the controller.

12. The apparatus according to claim 10 , wherein the burner unit is located remotely from the control room.

13. The apparatus according to claim 10 , wherein a plurality of burner units are provided.

14. The apparatus according to claim 13 , wherein at least one of the plurality of burner units is located remotely from the control room.

15. The apparatus according to claim 13 , wherein at least one of the plurality of burner units is located adjacent to the control room.
