Journal of Mechanical Engineering| Резюме: | The reliability of a high-power turbogenerator largely depends on its cooling system. The trouble-free and efficient operation of this system, in particular the gas cooler, is a problem that has not been fully resolved as of now. A modernized design of a gas cooler for a 325 MW turbogenerator, featuring high-finned bimetallic tubes, is proposed in the paper. To substantiate the efficiency of such a design and determine the heat transfer reserve of the gas cooler, its thermal state was calculated. The obtained results showed that the water overheating in the gas cooler is 5 °C. At the same time, one section of the gas cooler provides heat loss removal of 1266 kW at a hydrogen flow rate of 6.66 m3/s and a cooling water flow rate of 200 m3/s, which meets the requirements for this gas cooler. |
