Definitions

  • the invention relates to a magnetoaerodynamic apparatus, comprising, for the hot gas circulation, a combustion chamber connected to a properly so called magnetoaerodynamic duct, and within the walls of which a coolant ows.
  • this coolant which can be the combustive component of the combustion mixture, is on the one hand to maintain the walls at a temperature permissible with the heat resistance characteristics of the materials known at present, on the other hand to recuperate the calories which pass through these walls and use them to preheat the combustive.
  • the object of the present invention is a magnetoaerodynamic apparatus using the above mentioned principles of the main patent, but comprising two magnetoaerodynamic conduits arranged'side by side and head to tail in the magnetic field of a single electromagnet.
  • the coolant is compulsorily the combustive component used for the combustion, or an element of this combustive.
  • the coolant is fed into the wall, in the vicinity of the combustion chamber, and flows in the same direction as the conducting gases from which the electricity is drawn. At the end of its run, the coolant is directly injected into the combustion chamber adjacent to the other magnetoaerodynamic conduit.
  • Such method exhibits many advantages which can be classified into two categories: thermal advantages and electrical advantages.
  • the antisystematic-type circulation i.e. in which the coolant iiows in the same direction as the gas to be cooled, has the advantage 'to maintain the whole surface of the cooled wall at a more homogeneous and more constant temperature.
  • the section available for the coolant between the two magnetoaerodynamic conduits so as to set the heat transfer coefficient to the correct value.
  • both electric circuits can be series connected whence a compact apparatus delivering a voltage which will be twice that of a single generator.
  • the intermediate electrodes are interconnected, no problem of connection arises from the juxtaposition of both generators.
  • FIGURE 1 is a longitudinal section of a device according to the invention.
  • FIGURE 2 is a cross-section according AA of the same device.
  • two magnetoaerodynamic generators G1 and G2 are arranged in a same refractory unit R.
  • Each of these two head-to-tail assembled generators comprises an inlet Cal or Ca2 for the fuel, a combustion chamber Ch1 or Ch2 and a nozzle T1 or T2.
  • the electrodes are represented by E, E1 and E2 being the external connections.
  • the combustive component assigned to G1 generator is fed into O1 and flows along the whole G2 generator before being fed into I1 in Chl combustion chamber.
  • the combustive component assigned to G2 generator is fed into O2 and liows along the whole G1 generator before being fed into I2 in C112 combustion chamber.
  • pole pieces which must create a field perpendicular to both electrodes and gaseous iiow can not be shown in the figure, since they are parallel to the projection plane.
  • FIGURE 2 it can be seen the fitting of pole pieces N and S and the arrangement of the cooling pipes around the magnetoaerodynamic conduit.
  • a power plant comprising: a first housing defining a first combustion chamber portion and a fluid communicating first exhaust portion; a second housing defining a second combustion chamber portion and a fluid communicating second exhaust-portion; said first and second housings being mounted closely adjacent to and substantially parallel to each other; said first combustion chamber portion being closely adjacent to and transversely aligned with said second exhaust portion; said second combustion chamber portion being closely adjacent to and transversely aligned with said first exhaust portion; first conduit means for conducting a coolant fluid from said first combustion chamber portion to said first exhaust portion in closely adjacent heat exchange relationship, and for discharging the thus heated coolant into said second combustion chamber portion; second conduit means for conducting a separate coolant fluid from said second combustion chamber portion to saidsecond exhaust portion in closely adjacent heat exchange relationship, and for discharging the thus heated coolant into said first combustion chamber portion.
  • each of said housings constitute an independent magnetohydrodynamic generator having electrodes; and including field means for producing a magnetic field for lboth of said magnetohydrodynamic generators.
  • housings are constructed of integrally joined common refractory material; and each of said conduit means consisting of passages formed in said refractory material of said housings.
  • housings are constructed of integrally joined common refractory material; and each of said conduit means consisting of passages formed in said refractory material of said housings.
