Abstract

PURPOSE: To obtain uniform effluence velocity distribution to improve efficiency, by forming the section of the nozzle box part of a spiral casing in flat and symmetrical to the effluence direction.
CONSTITUTION: A sprial nozzle box part 21 is arranged so that the sectional shape of a flow passagw is in symmetrical to the direction of effluence to the nozzle throat part 22. The nozzle box part 21 has a flat shape in order to avoid sharp variation of shape, and is connected to the nozzle throat part 22 with smooth curve 23. Thus, the distribution B of effluence velocity in the radial direction in this invention becomes more uniform than the conventional A.
