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.

Abstract: The invention relates to an incinerator for crematories, including a combustion chamber provided with charge inlet, flue gas outlet, supply means for combustion air, heat supply means and ash outlet. The novelty resides in the fact that the combustion chamber is placed in a unit which is movable, between two positions, relative to at least one stationary end wall in which the charge inlet and the flue gas outlet are provided, and is divided into at least two compartments which communicate with each other at some distance from the flue gas outlet and are adapted to be positioned, one at a time, at respectively the charge inlet and the flue gas outlet. The heat supply means works in the compartment present at the charge inlet at just that moment, and the combustion gases from said compartment will pass the other compartment on their way towards the flue gas outlet.
