Patent ID: 6966268

Claim:
A centrifugal combustion method using air-flow in a furnace, comprising the steps of: supplying air to a space formed between a first combustion chamber positioned at an upper part of a fuel tank and an outer tub wrapping said first combustion chamber through one or more ventilators tangentially connected to a lower part of said outer tub such that the air supplied through said ventilators is preheated and ascended with revolving inside of said space formed between said first combustion chamber and said outer tub; and, controlling the direction of the air-flow that ascended to the top of said space formed between said first combustion chamber and said outer tub so that the necessary amount of air descends inside of said first combustion chamber with revolving in contact with an interior wall of said first combustion chamber, and the remaining part of said air further ascends inside of a second combustion chamber located at an upper part of said first combustion chamber with revolving in contact with an interior wall of said second combustion chamber, the revolving of said air in contact with said interior walls of said combustion chambers being accomplished by the continuous supply of the air by said ventilators.
