Title:
ガス・蒸気複合タービン設備
Document Type and Number:
Japanese Patent JP4172914
Kind Code:
B2
Abstract:
A gas and steam-turbine plant having a heat-recovery steam generator which is connected downstream of a gas turbine on a flue-gas side is described. The heat-recovery steam generator has heating surfaces connected in a water/steam circuit of a steam turbine. Cooled air for cooling the blades can be directed via an evaporator to the gas turbine. The evaporator is connected on a secondary side to the water/steam circuit and opens on an outlet side into a steam-collecting chamber. The steam-collecting chamber is connected to a water/steam drum via feed pipes connected in parallel on a steam side. The intention is to ensure that, during the transport of the water/steam mixture from the evaporator to the water/steam drum, a separation of the two-phase mixture is reliably prevented. Therefore, the steam-collecting chamber has a number of sub-chambers, which are connected to one another and in each case assigned to a feed pipe.
