US 5,101,739 A · Tire gassification and combustion system

Abstract

A system for disposing of materials such as vehicular tires and similar substantially organic matter and generating useful heat therefrom includes a first chamber, referred to as a gassification chamber, capable of holding a plurality of tires. The gassification chamber has an access way allowing for insertion of whole tires therein where they will be burned at a relatively low temperature resulting in incomplete combustion and the generation of combustible gases. A first air inlet is positioned substantially at the bottom of the gassification chamber with a first blower connected thereto. A gas outlet is positioned a first distance above the bottom of the gassification chamber confining the burning to the lower end of the gassification chamber. The combustible gas is removed and is conveyed to the lower end of a second chamber, referred to as a combustion chamber. A second blower is connected to a second air inlet at the bottom of the combustion chamber and an electric arc is used to ignite the mixture of air and combustible gas. A third air inlet is positioned a distance above the second inlet in the combustion chamber, and with a third blower connected to the third air inlet, promotes complete combustion of the combustible gases which are produced in the gassification chamber. The hot combustion products exit the combustion chamber relatively free of pollutants and are directed to a heat exchanger where the heat generated is put to a useful purpose.

Dependent claims

A system for disposing of a material such as vehicle tires and similar substantially organic matter and generating useful heat therefrom, the system comprising:

gassification means for holding an amount of the material to be disposed while the material is allowed to partially combust and for containing combustible gas produced thereby, the gassification means comprising a substantially air tight gassification chamber having at least one access way for inserting the material therein;
inlet means for receiving a controlled amount of oxygen containing gas into the gassification means, the inlet means comprising a tuyere disposed in the air tight gassification chamber and a blower connected to the tuyere;
removal means for removing the combustible gas from the gassification means, the removal means comprising a gas outlet located above the tuyere in the gassification chamber such that substantially amounts of the combustible gases produced by the partially combusted material exits through the gas outlet;
primary combustion means for receiving and mixing the combustible gas removed from the gassification means with an oxygen containing gas and burning the combustible gas;
and
means for directing the combustion products to a heat utilizing device.
