通过硫化氢的部分燃烧形成硫蒸气。操作喷枪以使在燃烧室内喷枪点火产生火焰。至少一个含硫化氢的第一可燃气流从喷嘴的第一区域供给火焰。从喷嘴流出的第一氧化气产生的至少一个第二气流与第一可燃气在火焰处混合。从围绕并与第一区域间隔的喷嘴的第二区域供给火焰第三气流。至少一个第四气流与第二可燃气在火焰处混合。至少一个第五也即最外气流与第二可燃气在火焰处混合。 Sulphur vapour is formed by partial oxidation of hydrogen sulphide. A burner is operated so as to establish a flame in a furnace in or into which the burner fires. There is supplied to the flame from the first region of the mouth of the burner at least one flow of a first combustible gas comprising hydrogen sulphide. At least one second flow of a first oxidising gas is caused to issue from the mouth of the burner and mix in the flame with the first combustible gas. There is supplied to the flame from a second region of the mouth of the burner surrounding and spaced from the said first region at least one third flow of a second combustible gas comprising hydrogen sulphide. At least one fourth flow of a second oxidising gas is caused to issue from a region or regions of the mouth of the burner surrounded by said second region and mix in the flame with the second combustible gas. At least one fifth, outermost flow of a third oxidising gas is caused to mix in the flame with the second combustible gas. A resultant gas mixture including sulphur vapour, water vapour, sulphur dioxide, hydrogen and residual hydrogen sulphide is withdrawn from the furnace.
