Abstract:
Calculate ejecting coefficieat of jet flow using heat balance analysis
method , the heat balance is between the heat release of working steam
expansion and the heat absorbing of mixing gas to be pressed, this
process is heat insulation processing in every stage ejector and the
state at exhausting port of ejector must be located truthful
superheating situation. Experimental ejecting property of steam-jet pump
which is designed has high degree of adaptability comparating with the
rata of desiging . Mass flow to be ejected gas by unit mass flow of
working steam at same degree of vacuum is increased and the energy
consumption is decreased.
Key words: Steam-jet pump Ejecting coefficient of jet flow
