Combined Gas-and-Steam Power Plant

Abstract

The present disclosure relates to power plants. Teachings thereof may be embodied in methods for operating a combined gas-and-steam power plant and/or combined gas-and-steam power plants. For example, some embodiments may include a method for operating a combined gas-and-steam power plant comprising: generating steam with waste gas from a gas turbine; driving a generator for providing electrical current via a turbine device; and using at least part of the heat in the steam to affect an endothermic chemical reaction.

What is claimed is: 
     
         1 . A method for operating a combined gas-and-steam power plant, the method comprising:
 generating steam with waste gas from a gas turbine;   driving a generator for providing electrical current via a turbine device; and   using at least part of the heat in the steam to affect an endothermic chemical reaction.   
     
     
         2 . The method as claimed in  claim 1 , further comprising performing an exothermic chemical reaction fusing products of the endothermic chemical reaction;
 wherein heat is released by the exothermic chemical reaction to heat at least part of the combined gas-and-steam power plant.   
     
     
         3 . The method as claimed in  claim 2 , further comprising generating steam with heat released in the exothermic chemical reaction to heat at least part of the combined gas-and-steam power plant. 
     
     
         4 . The method as claimed in  claim 2 , wherein a heat exchanger transfers at least part of the heat released to the at least part of the combined gas-and-steam power plant or to a medium for heat storage. 
     
     
         5 . The method as claimed in  claim 1 , wherein at least part of the heat in the steam is used during normal operation of the combined gas-and-steam power plant to effect the endothermic chemical reaction, wherein normal operation includes driving the generator and providing electrical power with the generator. 
     
     
         6 . The method as claimed in  claim 5 , further comprising, after normal operation, supplying heat to the combined gas-and-steam power plant by means of the released energy, whilst the provision of electrical power effected by the generator is halted. 
     
     
         7 . The method as claimed in  claim 1 , further comprising transferring heat from the steam through a heat exchanger to educts of the endothermic chemical reaction. 
     
     
         8 . A combined gas-and-steam power plant comprising:
 a turbine device;   a generator driven by the turbine device to provide electrical power; and   a gas turbine exhausting waste gas for generating steam for driving the turbine device;   a reactor supplied with heat from the steam to affect an endothermic chemical reaction in the reactor.
