摘要
以级内损失理论为依据,提出分别计算级内湿汽损失和其他级内损失的湿蒸汽区抽汽焓的计算模型。应用该模型分别计算了不同厂家、不同工况下的汽轮机组湿蒸汽区抽汽焓。结果表明:该计算模型具有良好的计算精度和适用性。
A calculation model was proposed for extraction enthalpy in wet steam region of a steam turbine based on stage loss theory by calculating the wet steam loss and other losses separately. The model was then used to calculate the extraction steam enthalpy of different turbines under various conditions. Result show that the calculation method has high precision and good adaptability.
