Abstract: An incinerating furnace, such as a cremation furnace or other batchwise chargeable furnace, is arranged with a main combustion chamber (1), from which the fumes are adapted to be led away through a following chamber arrangement (6-17) connected with a flue.

Abstract: A combustion process and a plant therefor, said process comprising the steps of introducing combustion material into a first chamber included in the plant and burning said combustion material therein, and finally burning out and treating in a second chamber residual products, such as gases and gas-borne components as well as slag, ash and the like passing into said second chamber from said first chamber.The novelty of the process resides in that the combustion in the first chamber is controlled so that a pyrolitic process takes place therein and that combustible gases expelled during said process are led to the second chamber in which the gases are burnt while yielding high heat which is utilized for melting the slag, the air and the like, and in that air or oxygen is supplied to bring about decarbonization of the slag.
