Definitions

  • the two heat exchangers 2.5 are replaced by one Heating gas 56 heated, which in the case of a burner fired boiler flue gas or in the case of waste heat utilization a gas turbine can be exhaust gas.
  • a line 20 runs from the separator 6A a further pump 21 and a further control element 22 to the outlet line 4, in particular to the warm end the first heat exchanger 2.
  • feed water flowing into the container 6 can alternatively flow into the flow line 15, as indicated by the dashed arrow 38.
  • the Steam drum 6 a line 26 with a pump 27 and a Control element 28 to the cold end of the first heat exchanger 2 or to the inlet line 3.
  • the dashed lines is drawn, branches from the flow line 15 a line 45 which merges into line 26.
  • the second control element 11 in the bypass line 8 and the control element 28 in the line 26 are in the open position, the pump 27 is in operation.
  • FIG. 9 shows a circuit arrangement according to an eighth embodiment of the invention with a Rotary drum evaporator with the steam drum 6 as second thermal system.
  • water can escape the flow line 15 via line 30 into the line 54 stream.
