FIELD: process engineering.
SUBSTANCE: invention may be used in chemical industry. Device 1 and method are used to evaporate, at least, one of the following reagents, i.e. solution of reducer precursor and reducer precursor. Device comprises, at least, one electrically heated heating zone 2. Said heating zone 2 comprises, at least, one electrical heater 3 with heating resistor 4 self-adjusted nearby significant temperature. Electrical resistor 4 is characterised by electric resistance variation curve related to temperature and having, at least, one kink point. Curve of derivative of said electric resistance variation curve, in temperature range related to said kink point, features full width at the level of semi-peak, equal to not over 40 K. In the range of significant temperatures, said electric resistance variation curve features rise exceeding 1 Ohm/K.
EFFECT: simplified and fast adjustment of evaporation.
