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.

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.

A combustion chamber of a gas turbine working on liquid fuel includes a tubular enclosure ( ) having at least one pressurized air inlet, a liquid fuel injection means ( ) positioned on or in proximity to the longitudinal axis (XX&prime;) of the tubular enclosure, and an outlet to the turbine. The fuel injection means ( ) includes a series of orifices ( ) arranged so as to create separate fuel jets, the jets being arranged in the direction of the generatrices of a cone with an angle ranging between 30&deg; and 60&deg; at the vertex thereof. The chamber includes at least two types of pressurized air inlets placed close to each other, the first one ( ) taking in the air helically around the longitudinal axis of the combustion chamber, the second air inlet ( ) being tangential to enclosure ( ) so as to create, around the fuel jets, counterrotating flows intended to improve mixing of the air and of said fuel. The assembly preferably works at a pressure ranging between 2 and 30 bars and with a fuel/air ratio ranging between 0.4 and 0.8.

The invention describes a nozzle and a burner for oil-well tests comprising a plurality of nozzles. The nozzle comprises means for injecting an air-oil mixture to be burnt in the direction of a combustion zone, the flow of air at the outlet of the nozzle allowing the air in the air-oil mixture to create an air induction effect, that is to say entrainment of air, which is sufficient along the whole length of the jet to ensure the combustion.

Low pollution burner for oil-well tests

A parallel flow liquid fuel burner is disclosed which has a device for injecting fuel in a central flame stabilizer; the stabilizer comprises a blade-containing rose situated around a central hub itself situated around the injection device and the injection device comprises several fuel injection orifices adapted to provide separate elementary flames.
