Abstract: Using heat balance analysis method based on the working
steam in mixing gas at exhausting port of ejector to be located
superheating situation to calculate ejecting coefficient, the heat
balance analysis consider both relation on expansion of working steam
pass to compression of mixing gas and influence of the temperature
difference on inlet state of ejector pass to outlet state of nozzle, and
that the influence of heat value change on gas mixing process. That is
concentrate the all change relation on heat value at ejector working
into calculating result. So that not only the real temperature of mixing
gas at exhausting port of ejector can be achieved but the coincidence
degree is increased between calculating result and real value at
working.
