AUTONOMOUS POWER PLANT WITH FLUIDYNE ENGINE Russian patent published in 1999 - IPC

FIELD: heat-power engineering; plants working by Stirling cycle. SUBSTANCE: during operation of engines 1 and 2, forced oscillations of columns of liquid arise in outlet tubes 8 and 9. Reciprocating motion of columns of liquid in tubes 8 and 9 causes motion of gas through chamber 7 setting turbine 10 in rotation and generating useful mechanical or electrical energy; synchronism of motion of levels of columns of liquid in outlet tubes 8 and 9 (in their anti-phase) is determined by shift in phase between fluidyne engines 1 and 2 adjusted through throttle valve 11. EFFECT: enhanced efficiency of plant as a whole; simplified procedure of conversion of oscillatory motion in outlet tubes of engine into useful mechanical or electrical work. 1 dwg
