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 (1) comprises a cylindrical shell (11), the discharge means comprise a pipe (6) having the same axis as the chamber and arranged inside said chamber, and fuel injection means (7) is arranged substantially tangential to said cylindrical shell so that the fuel follows a circular motion around said pipe in the chamber.

1. A method of generating heat energy, comprising combusting a fuel comprising organic vegetable or mineral material in a device comprising a combustion chamber, at least one fuel injection means, chamber preheating means provided in the vicinity of the fuel injection means, at least one air inlet,
1. A method of generating heat energy, comprising combusting a fuel comprising organic vegetable or mineral material in a device comprising a combustion chamber, at least one fuel injection means, chamber preheating means provided in the vicinity of the fuel injection means, at least one air inlet, and hot fumes discharge means, said chamber comprising a cylindrical shell, said discharge means comprising a pipe having the same axis as the chamber and arranged inside said chamber, and the fuel injection means being arranged substantially tangential to said cylindrical shell so that the fuel follows a circular motion around said pipe in the chamber, wherein an annular volume of the combustion chamber is determined in order to optimize combustion by adjusting the transit time of the hot gases.2. A method as claimed in claim 1, wherein the composition and/or spraying of the fuel is adjusted so as to have a sufficient amount of fine droplets and/or particles to optimize spontaneous ignition of the fuel.3. A device intended for spontaneous combustion of a fuel comprising organic, vegetable or mineral materials, said device comprising a combustion chamber, at least one fuel injection means, chamber preheating means provided in the vicinity of the fuel injection means, at least one air inlet, and hot fumes discharge means, characterized in that said chamber comprises a cylindrical shell, said discharge means comprise a pipe having the same axis as the chamber and arranged inside said chamber, and the 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 and comprises three concentric tubes intended for injection of the fuel, of the air allowing said fuel to be sprayed and of the combustion air.4. A device as claimed in claim 3, wherein the injection means comprises a spray nozzle consisting of a disk pierced with a port allowing passage of the sprayed fuel jet, the shape of the disk being such that it creates swirls favouring air/fuel mixing in the chamber.5. A device intended for spontaneous combustion of a fuel comprising organic or vegetable materials, said device comprising a combustion chamber, at least one fuel injection means, chamber preheating means provided in the vicinity of the fuel injection means, at least one air inlet, and hot fumes discharge means, characterized in that said chamber comprises a cylindrical shell, said discharge means comprise a pipe having the same axis as the chamber and arranged inside said chamber, and the 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, wherein the fuel is a mixture of water and of organic or vegetable matter ground into bits whose average size is less than 10 mm.6. A device as claimed in claim 5, wherein the fuel injection means is arranged at a distance from the end of discharge pipe and the length of said pipe in the combustion chamber is determined to obtain a sufficient transit time of the products during combustion in the chamber before they are discharged through said pipe.7. A device as claimed in claim 5, wherein two diametrically opposite fuel injection means are provided.8. A device as claimed in claim 5, wherein the chamber comprises at least one secondary air inlet opening onto the vicinity of the end of the discharge pipe.9. A device as claimed in claim 8, wherein said air inlet is substantially tangential to said shell and so oriented that the secondary air in the chamber moves in the opposite direction in relation to the motion of the fuel.10. A device as claimed in claim 8, wherein there are two diametrically opposite air inlets.11. A device as claimed in claim 5, wherein said preheating means comprise inlets for hot air coming from burners.12. A device as claimed in claim 5, wherein the chamber comprises, in the lower part thereof, reception and discharge means intended for the ultimate combustion residue.13. A device as claimed in claim 5, wherein the discharge pipe cooperates with a heat exchanger in order to provide hot water or steam.14. A device as claimed in claim 5, wherein a fan provides combustion air, a compressor provides spraying air, a pump supplies the injection means with fuel.15. A device as claimed in claim 5, wherein at least one additive is added in order to stabilize the combustible mixture.16. A device as claimed in claim 5, wherein an amount of hydrocarbons is added in order to miss the moan net calorific value of said mixture.17. A device as claimed in claim 5, wherein the organic matter comes from greasy waste.18. A device as claimed in claim wherein the greasy waste comprises waste from palmipeds.19. A device as claimed in claim 19, wherein the fuel is a mixture of water and of organic, vegetable or mineral matter ground into bits whose average size is less than 5 mm.20. A device as claimed in claim 19, wherein at least one additive is added in order to stabilize the combustible mixture.21. A device as claimed in claim 19, wherein an amount of hydrocarbons is added in order to raise the mean net calorific value of said mixture.22. A device as claimed in claim 19, wherein the organic matter comes from greasy waste.
