Definitions

  • At least the portion of the heat contained in the exhaust gas downstream from the steam generator ( 20 ) is transferred, via a heat exchanger ( 38 ), to educts of the endothermic chemical reaction.
  • Heat is released in the course of the back reaction.
  • This heat that becomes free or is released in the course of the back reaction can be used for heating purposes, in particular for district heating purposes.
  • the water is provided at a temperature T 7 , for example, the water being supplied at the temperature T 7 to the heat exchanger 42 .
  • the water is heated to a temperature T 8 , for example the temperature T 7 being 65° C. (degrees Celsius) and the temperature T 8 being 100° C.
  • the temperature T 8 is thus greater than the temperature T 7 , the water having the temperature T 7 upstream from the heat exchanger 42 , and the temperature T 8 downstream from the heat exchanger 42 .
  • the water has a pressure of 14.5 bar, the water being provided at this pressure and at the temperature T 7 , and supplied to the heat exchanger 42 .
  • the use of the heat exchanger 38 makes it possible to realize a spatial separation of the educts of the forward reaction from the exhaust gas, such that the exhaust gas does not come into direct contact with the educts of the forward reaction.
  • the exhaust gas does come into direct contact with the educts of the forward reaction, and in this case flows onto, or around, the educts.
  • the heat exchanger 38 for example, is then omitted.
  • the use of the heat exchanger 42 makes it possible to realize a spatial separation of the educts and/or products of the back reaction from the water that is heated by means of the released heat, such that the water does not come into direct contact with the educts and/or products of the back reaction.
  • the water does come into direct contact with the educts and/or products of the back reaction, and in this case flows onto, or around, the educts and/or products.
  • the heat exchanger 42 for example, is then omitted.
  • thermochemical heat accumulator 34 it is conceivable to supply only a portion of the exhaust gas downstream from the steam generator 20 to the heat exchanger 38 , and/or only a portion of the water to the heat exchanger 42 , to ensure, in particular, an at least substantially continuous heating of the water by means of the thermochemical heat accumulator 34 .
