Portable combustion system with first and second air sources

A combustion system comprising:

• a combustion chamber frame having a combustion chamber frame first end and a combustion chamber frame second end;
• a base frame having a base frame first end and a base frame second end;
• the combustion chamber frame second end being pivotably attached to the base frame second end;
• the combustion chamber frame defining a combustion chamber;
• a perforated plate forming a bottom surface of the combustion chamber, and the perforated plate having a plurality of openings formed therein;
• the combustion chamber being open along at a top thereof to facilitate feeding of waste material into the combustion chamber;
• at least one blower for supplying combustion air to the combustion chamber to assist with combustion of the waste material;
• and
• the at least one blower being coupled to an air manifold for supplying a first source of combustion air across the top of the combustion chamber and forming an air curtain across the open top during operation of the combustion system, and the at least one blower being coupled to an air supply duct for supplying a second source of combustion air through a bottom surface of the perforated plate and into the combustion chamber to assist with combustion of the waste material contained within the combustion chamber;
• wherein a base plate is located below the perforated plate, a plenum is defined between the base plate and the perforated plate, and the plenum receives and distributes the second source of combustion air from the air supply duct through the plurality of openings formed in the perforated plate and into the combustion chamber.
