A hazardous waste incineration system is provided in which a series of interconnected combustion chambers are employed to obtain successively higher temperatures in successive chambers, the gaseous products of combustion in each chamber being supplied to the next chamber in the series to act as a high temperature environment and promote the burning of hazardous wastes in successive chambers which require successively higher temperatures to become volatilized and break down into their constituent elements. Preferably, the successive chambers have successively larger volumes so that successively greater amounts of hazardous wastes, which may be of successively lower heat values and require successively higher temperatures to be broken down, may be burned in the successive combustion chambers of the series.
The method of disposing of hazardous wastes which comprises the step of, burning low viscosity, high heat value liquid hazardous waste at a relatively slow rate in a first combustion chamber, supplying the gaseous products of combustion to a second combustion chamber to act as a sustained high temperature environment therein, and burning in said second chamber at a substantially increased rate liquid hazardous waste of somewhat less heat value than the hazardous waste burned in said first chamber.
The method of disposing of hazardous waste, which comprises the steps of burning hazardous waste in a first combustion chamber at a relatively slow rate, supplying the gaseous products of combustion of said first chamber to a second combustion chamber to act as a sustained high temperature environment and promote the burning of hazardous waste therein, and burning hazardous waste in said second combustion chamber at a rate substantially greater than the rate at which hazardous waste is burned in said first combustion chamber.
