The article presents the results of thermal tests of the condenser of the steam turbine PT-25-90 UTZ during off-design operation. An increase in the pressure in the condenser for the possibility of heating the district heating water is considered. The pressure in the condenser was artificially deteriorated both by lowering the vapor pressure of the ejector and by reducing the flow rate of the cooling water. The maximum pressure was 70.8 kPa. The maximum exhaust steam temperature was 154 °C. The heat transfer coefficient of the condenser has deteriorated by 75% in comparison with the design mode of operation.

非设计模式下冷凝器的实验评估

本文介绍了 PT-25-90 UTZ 汽轮机冷凝器在非设计运行期间的热测试结果。考虑增加冷凝器中的压力以加热区域供暖水的可能性。通过降低喷射器的蒸气压和降低冷却水的流量，人为地降低了冷凝器中的压力。最大压力为70.8kPa。最高排汽温度为 154 °C。与设计运行模式相比，冷凝器的传热系数下降了 75%。
