METHOD OF POWER CONVERSION OF GAS STREAM (VERSIONS) AND DEVICE FOR ITS IMPLEMENTATION (VERSIONS) Russian patent published in 2009 - IPC F03D1/04 F03D9/02 

FIELD: mechanical engineering.

SUBSTANCE: method of power conversion of gas stream consists in that gas stream is divided for concentric gas streams with variable in the direction of feeding ring cross-sections. Gas streams are shifted relative to each other in the direction of delivery, many-stage ejected and they are accelerated by means of introduction of output cross-section of channel of following stage of ejection into critical section of channel of previous stage of ejection and again are joined into waste gas flow. Gas flow is fed to separation to the last ejection stage in the form of stream with cross sections of ring configuration, herewith aggregate of central parts of cross sections of ring configurations composes unreclaimable for separation and conversion central cylinder-shaped part of gas stream. Inner diametre of cross section of stream at input cross-section of channel of the last ejection stage is less than diametre of input cross-section. Inner diametre of cross-section of stream at critical section of channel of the last ejection stage is less than diametre of this critical section. Central cylinder-shaped part of gas stream is sealed isolated from direct action of moving gas stream with border of insulation, located at section from input cross-section of channel of the last ejection stage up to critical section of channel of last but one ejection stage, it is left opened from the side of critical section of channel of last but one ejection stage of gas stream, sealing connected it with opened or closed volumes, located out of limits of moving gas stream.

EFFECT: efficiency rising.
