Abstract

A low-pollutant system for waste materials treatment includes a process chamber for converting organic components of the waste materials into a flammable gas and a two-stage vortex burning chamber for complete combustion of the flammable gas. The vortex burning chamber includes a first substantially-horizontal combustion chamber and a second substantially-vertical combustion chamber disposed at a right angle to each other and communicating therebetween. The first combustion chamber has an inlet portion for receiving the flammable combustion gas from the gas generator means for injecting primary air into the first combustion chamber, thereby forming a mixture of air and the flammable gas and thereby igniting the mixture for partial oxidation thereof. The first combustion chamber has a converging distal portion for discharging the partially-oxidized mixture of air and the flammable gas tangentially into the second combustion chamber, where the gas is mixed with the secondary air which is injected tangentially into the second combustion chamber, thereby substantially completely oxidizing the partially-oxidized mixture of air and the flammable gas. The second combustion chamber has an outlet portion for discharge of the waste gas resulting from the two-stage combustion of the flammable gas and the solids separated from the gas.
