Definitions

  • the invention has for its object in one unit Generate steam and in a piston engine in mechanical Convert energy.
  • the steam generation is achieved in that with a commercially available burners gaseous or liquid fuels in a combustion chamber made of ceramic material or Highly heat-resistant steel can be burned. This creates temperatures of over 1,000 ° C in the combustion chamber.
  • the advantage of this method is that weak gases such as biogas, landfill gas or wood gas over a longer period Burning period burned at very high temperature become. Remaining pollutants that are after the Purification of the gases should still be in these at the high temperatures and over the duration of the Cracked burn time.
  • Flash steam is used for steam generation, which means that there is a water jacket around the ceramic combustion chamber . This water is superheated to hot water and then fed to the expansion space of the steam engine, where it evaporates. The expanded steam is expelled from the piston through the opened valves.
  • Fig.1 shows such a steam engine.
  • Fuel is supplied to the burner 14 through the control plug 13 .
  • the fuel is burned and hot water is generated in the ceramic combustion chamber 15 .
  • the 16 thermometers and 17 manometers display the current status of the hot water.
  • the safety valve 18 is blown off.
  • the pressure sensor 11 measures the actual pressure in the hot water chamber and controls the pressure maintaining pump via the controller 10 .
  • the angle sensor 4 which controls the solenoid valves 6 via the control device 5 .
  • the control unit 5 of the time and duration can be eiocyte 6 for opening the solenoid valves.
  • Fig. 8 Fig. 1 When steam is sprayed in, a pressure builds up above the piston 12 , which opens the control piston 6 against the spring 4 via the control line 1 . The resulting pressure also presses the condensate 16 through the opening 7 into the feed water tank. About 20 ° after TDC , the piston 12 closes the control line 1 so that no further pressure presses on the control piston.
