Abstract (en)
[origin: EP0458685A1] The invention relates to a process for spraying a liquid with the aid of at least one auxiliary fluid, such as a gas, this process comprising the use of: - an annular flow of the said liquid (27), - an annular flow of a primary gas (38), - an annular flow of a secondary gas (23) which is identical to or different from the previous gas, the said process consisting in: a) directing the flow of liquid within the said flow of primary gas in the flow direction of the latter, b) producing an annular thin film of liquid by directing the coaxial flows of liquid and primary gas onto the periphery of a ring (30), one of the free ends of which is shaped in the form of a ridge, c) spraying the liquid at the end of the said ridge. According to the invention, the ratio of the total mass of gas with respect to the total mass of the liquid is less than 0.5. <IMAGE>
