THERMAL UNIT Russian patent published in 1997 - IPC

FIELD: thermal engineering; thermal power stations. SUBSTANCE: thermal unit has compressor, combustion chamber, combustion chamber fuel feeder, device for energy release from working medium. Combustion chamber and device for energy release from working medium are provided with duct of nonconducting material with two parts placed at certain angle to each other and joined at ends. Duct section at its part-to-part joint is made of conducting material in the form of concave surface. This section is concave portion of convexo-concave hollow body. Outer surface of convex part is electrically connected to one pole of DC supply better through load resistor. Second pole of current supply is connected to duct fuel feeder. Compressor outlet is connected to at least one end of duct. EFFECT: improved design. 7 cl, 2 dwg
