What are the functions of a steam turbine condenser?

The function of a steam turbine condenser is to condense the exhaust steam from the steam turbine into water. In addition to condensing the exhaust steam for reuse in the boiler, the condenser also establishes and maintains a vacuum at the steam turbine exhaust. Below are detailed explanations of the steam turbine condenser: 1. Based on the method of steam condensation, condensers can be classified into surface-type and mixing-type. In surface-type condensers, steam, separated from the cooling medium, is condensed into liquid on the cooling surface. The cooling medium can be water or air. Water-cooled surface-type condensers are further divided into single-pass and double-pass types based on the flow direction of the cooling water. In mixing-type condensers, steam is condensed into liquid by mixing with the cooling medium. The condensed steam can be water vapor or vapor of other substances. 2. Excessively low vacuum in the condenser can severely impact the safe and economical operation of power plant units. One major cause of excessively low vacuum in the condenser is the scaling of condenser cooling tubes. Scaling in the condenser significantly affects its performance, not only increasing the turbine's terminal temperature difference and reducing the vacuum degree but also raising the exhaust temperature, thereby affecting the turbine's economy and safety.
Through years of driving experience, I've deeply realized that the turbine condenser plays a core role in heat dissipation and cooling within a car's air conditioning system. When the refrigerant exits the compressor as a high-pressure gas, the condenser located at the front of the vehicle dissipates heat through fan airflow and cooling fins, allowing the refrigerant to condense into liquid before flowing to the expansion valve for further cooling. If it malfunctions during summer drives, the AC fails, causing cabin temperatures to soar and increasing driver fatigue risks. I'm particularly attentive to regularly clearing dust and leaf blockages to prevent efficiency loss from blade contamination. This not only ensures cabin comfort but also protects the entire AC system from compressor overload damage. Proper maintenance also enhances energy efficiency, making long journeys more pleasant.
