Abstract
A combined gas and steam-turbine power generating station having a gas-turbine unit and a steam turbine unit, the gas-turbine unit having a gas turbine with a combustion chamber, a coal gasifier preceding the gas turbine unit, a heat exchanger plant including a raw gas/pure gas heat exchanger following the coal gasifier, a gas purifier following the heat exchanger plant, a pure-gas line leading from the gas purifier to the combustion chamber of the gas turbine, an air decomposition plant with a molecular sieve regeneration circuit preceding the coal gasifier and having an oxygen line feeding the coal gasifier and a nitrogen line leading to the combustion chamber of the gas turbine, and a nitrogen compressor connected in the nitrogen line, includes at least one air compressor preceding the air decomposition plant and the combustion chamber of the gas turbine, and an air line connecting the air compressor to an input of the air decomposition plant, the air line being divided into two parallel branches, one of the branches including therein a heat exchanger connected into the molecular sieve regeneration circuit of the air decomposition plant and the other of the branches including therein a nitrogen/air heat exchanger leading to the combustion chamber of the gas turbine.
