Abstract
Abstract The invention relates to a furnace for incinerating solid and liquid waste, the furnace having means for preheating the furnace chamber and for supplying heat in addition to that produced by combusting the waste. According to the invention, the furnace chamber is divided in two compartments by a divisional wall not substantially inhibiting heat transmission, one compartment to receive liquid waste, and the other to receive solid waste, each compartment having separate means for supplying air for the combustion.
