Kramer, R J

A waste incineration apparatus and method are provided having two serially connected combustion chambers for incineration of solid, semi-solid, and liquid waste material, each of which comprises combustible components. The combustion chambers are relatively positioned so that heated gaseous fluids produced by combustion of substantially solid and semi-solid waste are passed on to enhance combustion of liquids introduced into the second chamber. These gaseous fluids which are at a relatively high temperature include those that enable or support combustion of liquid waste and may also include those that are combustible when combined with additional combustion air. These gaseous fluids intermix with liquid waste entering the second chamber thereby enhancing the combustion characteristics of the liquid waste. Preferably, combustion in the first chamber is carried out in the presence of a substantial amount of excess air resulting in complete combustion and preheating of the remaining combustion air prior to its entry into the second combustion chamber. Alternatively, combustion in the first chamber is controlled by limiting the amount of combustion air admitted to that necessary to effect burning of the solids or semi-solids, but not sufficient for combustion of the gaseous fluids evolved as a result of the combustion process thereby forming a combustible gaseous fluid.
