STEAM-AND-LIQUID JET DEVICE WITH PRESSURE OF LIQUID ACROSS OUTLET EXCEEDING PRESSURE OF WORKING STEAM Russian patent published in 1998 - IPC

FIELD: production of heated liquid with pressure exceeding pressure of working flow. SUBSTANCE: jet device includes body housing steam nozzle. Body is divided along pass of working medium into intake chamber, transition diffuser and mixing chamber. Area of minimum cross-section (f_n)_m of steam nozzle exceeds area of minimum cross-section (f_c)_m of mixing chamber. Relation of values of mentioned areas lies within limits 1.1 ≤(f_n)_m/(f_c)_m≤ 3.7. Two other versions of realization of jet device differ from the described one by relation of values of specified areas lying within limits 4 ≤(f_n)_m/(f_c)_m< 10 and 12 ≤(f_n)_m/(f_c)_m≤ 20. EFFECT: possibility of production of heated liquid flowing from outlet of jet device with pressure exceeding pressure of working flow. 3 cl, 1 dwg
