ABSTRACT:
A method of incinerating in a main combustion chamber leading directly to two consecutive reburn stages. The main combustion chamber accepts bulk refuse onto a hearth floor. In the first reburn tunnel, a burner maintains the temperature of the gases above a predetermined set point. Above that set point, the burner assumes a low setting. Below it, a high setting increases the heat produced. Alternatively, the gas may go to its high setting below a first set point; to its low setting above a second set point; and proportionate at temperatures between them. This chamber also receives outside air to assist in the actual combustion process. From the first reburn chamber, the gases go to a second reburn chamber to complete the combustion. There, they receive additional oxygen for this purpose. At temperatures above a set point determined near the third chamber, additional air enters to prevent excessive temperatures. Fume burning of hydrocarbon containing gases may also take place in the double reburn tunnel. The entering gases should have a velocity of about 40 ft./sec. and the entrained particles should have a size less than about 100 microns.
