ENERGY EXTRACTING PNEUMOHYDRAULIC TURBINE Russian patent published in 1998 - IPC

FIELD: power engineering. SUBSTANCE: working wheel of axial-flow propeller hydraulic turbine is installed in housing with guide vane and suction apparatus. Cylindrical housing is connected with solar collector and compressor air source. Turbine does not require high-level reservoir and operates as energy pump. Air floatability force is converted into energy of water flow which is delivered to working wheel from below due to overflow of water at its displacement from working part by compressed air delivered higher and lower than working members. Amount of compressed air at floating up takes heat stored in water and converts it into mechanical work. EFFECT: possibility of using solar energy and energy of heat stored in water and air. 2 cl, 2 dwg
