Abstract: The invention relates to a method of combustion, in which waste, especially household and/or industrial waste, is subjected to a process (T) comprising at least one step in which the waste is pyrolysed and a gas mixture containing hydrocarbons is created, and then a step in which gaseous hydrocarbons are brought into contact with steam and with an oxidizing agent, and resulting in the production of a final gas mixture (FM) containing carbon monoxide and hydrogen, and then at least part of the carbon monoxide and of the hydrogen is used, as a mixture, as fuel, for example in a blast furnace (F) or in a cement kiln.

Abstract: A device for atomizing a liquid fuel comprising a central liquid fuel feed passage for feeding with liquid fuel an outer atomizing-gas feed passage for feeding with atomizing gas, these being coaxial overall,an atomizing head extending said passages, the head being equipped for each fluid with one or more ducts which converge into one or more nozzles made in the head and emerging in a combustion region in which the nozzles release a mixture of atomized liquid fuel and of atomizing gas, which head is held at the end of the coaxial passages by a nut screwed onto a wall of the outer passage,wherein the central liquid-fuel feed passage is surrounded by the atomizing-gas feed passage and the atomizing head includes a skirt surrounding inlets to the ducts for the liquid fuel, which skirt is received inside the central passage and the skirt and the said passage respectively have externally and internally complementing cross sections.
