High temperature condensate return facility is the key equipment in a closed condensate return system. Combined with jet pump and centrifugal pump, the new facility can solve the cavitations exist in transporting high temperature saturated condensate of centrifugal pump by increasing the pressure of jet pump. The dissertation analyses the differences between the theories of jetting under the return facility and that of single jet pump so as to set forth some basic concepts of jetting formulas under the condition of return facility. Consequently, the basic jetting formulas and the formulas of cavitations under that condition can be deduced, so as the efficiency formulas, characteristic formulas and performance formulas.
