receives the waste to be incinerated. An ignitionburner is provided in the first chamber to ignite the waste; the burner automatically turns off at waste incineration temperature.
Burning of the refuse is accomplished in three zones, each zone being provided with proper temperature and a supply of regulated air at low velocity by means of natural aspiration, controlled by thermal feedback wherein the changing of the refuse fire changes the heat and vacuum applied to a conduit and orifice system of fire air injection resulting in automatic combustion control. A second combustion chamber is spaced above and communicates with the first chamber. Separators are provided in each chamber for separating partially burned particles from the fully burned combustion gases and preventing the particles from rising beyond the respective separators. An after-burner is arranged to project a substantially horizontal flame into the second combustion chamber; the flame produced by the after-burner substantially filling the cylindrical second chamber and reducing any microscopic particles or unburned gases which have passed through the separators. The second chamber passes fully reduced combustion gas to the stack at a temperature of 2,000° Fahrenheit.
