STEAM-AND-LIQUID JET DEVICE WITH PRESSURE OF LIQUID ACROSS OUTLET EXCEEDING PRESSURE OF WORKING STEAM

摘要

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 (fn)m of steam nozzle exceeds area of minimum cross-section (fc)m of mixing chamber. Relation of values of mentioned areas lies within limits 1.1 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 10 and 12 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
