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 jaw crusher for bulky waste and like matter, comprising two groups of jaws or shanks movable towards and away from each other, the jaws or shanks within each group being spaced at an interval corresponding to the width of the jaws or shanks of the opposite group. The jaws or shanks of one group are adapted, as they move towards the other group, to travel at least partly into the interspaces between the jaws or shanks of the opposite group, and include driving units actuating at least one group of jaws or shanks in order to move them towards the opposite group. At least one of the jaws included in at least one group of jaws is movable relative to the remaining jaws of the same group, the jaws are individually movable by individually actuable driving units, and the driving units are provided with sensors for sensing exerted power and actuating a programmable central unit which controls the relative position of the jaws so that it will vary during the cutting-up operation.

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.
