FIELD: process engineering. ^ SUBSTANCE: invention relates to fluid evaporator. Proposed method consists in feeding into feed line 3 one first partial amount of fluid making a portion of preset volume at first discharge rate 17 and one second partial amount of fluid, other than the first one, at second discharge rate. Said partial amounts, are, at least, partially evaporated to produce vapor film between partial mount of fluid and feed line wall. Partial amounts are fed via feed line 3 to evaporation surface 5. Said partial amounts are fed onto portion of evaporation surface 5, its position being varied depending upon, at least, one of the following parameters: I) magnitude of partial amount of fluid, and II) discharge rate 17 of partial mount of fluid. ^ EFFECT: efficient evaporation, primarily, of urea. ^ 15 cl, 7 dwg |
