THE AIM OF THE INVENTION IS A DEVICE (100) FOR COOLANT COOLING IN A GAS TURBINE (2) WHICH, WITH A RELATIVELY SIMPLE CONSTRUCTION AND LOW PLANT COMPLEXITY PERMITS A PARTICULARLY HIGH DEGREE OF EFFICIENCY IN USING THE HEAT PRODUCED ON COOLING THE COOLANT FROM A GAS TURBINE (2). SAID AIM IS ACHIEVED, WHEREBY A NUMBER OF INTERCONNECTED EVAPORATOR TUBES (140,150, 160, 170) FOR A FLOW MEDIUM, ARE ARRANGED IN A COOLANT CHANNEL (102), CONNECTED TO A GAS TURBINE (2), TO FORM FORCED THROUGHFLOW STEAM GENERATOR. SAID DEVICE IS PREFERABLY USED IN A GAS AND STEAM UNIT WITH A WASTE HEAT STEAM GENERATOR ON THE EXHAUST GAS SIDE OF A GAS TURBINE (2), THE HEATING SURFACES OF WHICH ARE CONNECTED INTO THE WATER-STEAM CIRCUIT OF A STEAM TURBINE. THE EVAPORATOR TUBES (140, 150, 160, 170) OF THE DEVICE (100) ARE THUS CONNECTED ON THE INLET SIDE BY MEANS OF SUPPLY LINE (40,112) TO THE FEED WATER TRAIN OF THE WATER-STEAM CIRCUIT OF THE STEAM TURBINE.(FIG 4) |
