A method for operating a gas and steam combined cycle power plant

摘要

The present invention relates to a method for operating a gas and steam combined cycle power plant 10 in which a high temperature steam is produced using exhaust gas from a gas turbine 12, The high temperature steam serves to drive at least one generator (30) using at least one turbine device (22) to generate a current, said method comprising the steps of: branching at least a portion of the generated steam off and storing the diverted steam in the steam accumulator 34; Directing at least a portion of the vapor stored in the vapor accumulator (34) out of the vapor accumulator (34); Heating the vapor delivered out of the vapor accumulator (34) using heat released during an exothermic chemical reaction; And - directing the heated steam to the turbine device 22, wherein the turbine device 22 is driven using the supplied heated steam.
