The invention relates to a a gas and steam turbine device, and the refrigerant for cooling the gas turbine of the device. The gas and steam turbine (1) with a waste steam generator (4) which, seen from the flue gas, is located upstream from the gas turbine. The heated surfaces of the waste steam generator are connected to the steam-water circuit (20) of a steam turbine (21), the gas turbine being submitted to a reliable cooling process under various operating conditions. In order to refrigerate the gas turbine (6) coolant, the inventive system comprises a heat exchanger (74) which is connected, on the secondary side, in the water-steam circuit (76) linked as a locking element to the water-steam circuit (20) of the gas turbine (21).
(ZH) 一种燃气和蒸汽轮机设备及冷却该设备中燃气轮机用冷却剂的方法。该燃气和蒸汽轮机设备(1)包括一蒸汽轮机设备和一燃气轮机设备，该燃气轮机设备具有一空气压缩器(8)、一燃烧室(10)、一燃气轮机(6)，其中，该燃气轮机(6)的烟气侧与一个余热蒸汽发生器(4)相连，后者的发热面接入一个汽轮机(21)的水-汽环路(20)中；为了即使在不同运行条件时也可确保燃气轮机的可靠冷却，根据本发明，来自空气压缩器(8)的空气(L)输入燃气轮机作为燃气轮机的冷却剂，并且一个为冷却燃气轮机(6)用冷却剂而设置的热交换器(74)在次级侧接入与所述汽轮机(21)的水-汽环路(20)可截止地连通的一个独立的水-汽环路(76)中。
