<p>1. Combined gas and steam turbine power station (46) with a coal gasifier (49) connected upstream of the gas turbine power station part (60), a pure gas pipe (57) connecting the coal gasifier with the combustion chamber (47) of the gas turbine (48), an air separation plant (79) connected upstream of the coal gasifier with an oxygen pipe (87) feeding the coal gasifier and a nitrogen pipe (88) leading to the combustion chamber (47) of the gas turbine (48), a nitrogen compressor (89) connected in the nitrogen pipe, and at least one air compressor (62, 77) connected upstream of the combustion chamber of the gas turbine and the air separation plant, characterised in that in the air pipe (78) leading to the air separation plant (79) in the direction of flow downstream of the end compressing air compressor (62, 77), a heat exchange device (82, 83, 84) is fitted, in which the nitrogen pipe (88) and the pure gas pipe (57) are connected to separate heat exchangers (82, 83) through which the end compressing air flows.</p> |
