Abstract: A three-chambered combustion burner is provided with a seed fuel under pressure to burn simultaneously injected waste products such as incompletely combusted exhaust fumes or air entrained combustible solid waste. An explosive mixture is provided in a first chamber and ignited. The heated and pressurized gas products are ejected into a second smaller combustion chamber into which air is injected. The hot and incompletely combusted products in the second chamber explosively reignite and are ejected into a yet smaller third combustion chamber. Air is again injected into the third combustion chamber wherein the products again explosively reignite to be ejected through a jet nozzle. The heat energy output of the burner or its propulsive momentum thrust may be utilized as appropriate in other applications. The toxicity of the gaseous or solid waste products burnt in the chambers is reduced and oxidized by the injection of air and hydrolization of water also injected with the waste products.
