The present invention relates to a method and to a device intended for spontaneous combustion of a fuel comprising organic, vegetable or mineral materials, the device comprising a combustion chamber, at least one fuel injection means, at least one air inlet, hot fumes discharge means. Chamber () comprises a cylindrical shell (), the discharge means comprise a pipe () having the same axis as the chamber and arranged inside said chamber, and fuel injection means () is arranged substantially tangential to said cylindrical shell so that the fuel follows a circular motion around said pipe in the chamber.

Method and device for the autocombustion of oily organic waste,comprising a tangential heating furnace

Combustible compositions in the form of homogeneous water-in-oil and/or organic emulsions, deriving from heterogeneous fatty waste and containing solid particles in suspension are prepared by carrying out a dynamic homogenisation operation and an emulsification operation in the presence of an emulsifying agent and/or a base such as an alkali or alkaline-earth metal hydroxide. These combustible compositions can be used for combustion in a variety of furnace types.

The invention concerns a device for producing hot water comprising at least one burner (,) arranged to produce rapid combustion inside the combustion chamber. The combustion chamber consists of a sealed container (,) delimiting an internal volume separated from the water so as to allow dry combustion. Said container (,) is immersed in a water section (,) and it is extended by at least one smoke gas diffuser (,) diffusing the smoke gases above the water section within a mass of water showered by spraying means (,). A layer of nodules (,) can be interposed on the path of the smoke gases and the sprayed water so as to increase the thermal exchange generated, by direct contact between the smoke gases and the water spray, and by conduction between container (,) and water section (,). The invention enables to achieve excellent thermal efficiency levels while producing smoke gases with a reduced CO ratio.
