The Machinery Section has introduced the \"Question of the Day\" feature, which not only helps to foster an active atmosphere for technical discussions and guide the direction of such exchanges but also provides users with financial rewards, enabling them to experience various cool features. True or False: During normal operation of a turbine, the vacuum in the condenser is created by the ejector. ( ) Correct answer: Wrong. A vacuum is created when steam condenses into water, resulting in a sudden reduction in volume; this leads to a high level of vacuum within the condenser. Requirement for answering the question: Please reply with the answer you believe to be correct. If you provide a detailed explanation or analysis of the question and answer, you will receive an additional reward. Extra rewards will be given if your answer is correct and your explanation is thorough and accurate. Feel free to answer the questions. Please note: We will close this thread after 24 hours, and at that time we will announce the best reply (the best assistance), as well as the answer and explanation. Please do not answer the question repeatedly. As a reward for your effort, if you post a topic in this section within two days that provides a detailed explanation of the knowledge points related to this question, please reply or leave a comment in this post to inform us, and we will have a moderator award you + charm points. It is not allowed to simply copy and paste; original content is preferred, with at least some organization by the user along with personal insights.

Error: After leaving the low-pressure cylinder, the exhaust steam enters the shell side of the condenser. Circulating water supplied by the circulating water pump flows inside the condenser tubes as a cooling medium, which is used to condense the exhaust steam into water. As steam condenses into water, its volume shrinks sharply, which creates a high vacuum inside the condenser
