摘要
以50 MW等级余热利用补汽式汽轮机组为研究对象,提出汽水分离器前蒸汽干度的测量方法,分析主汽阀、调节阀的压损情况,给出该类型机组的发电机输出功率的修正系数,并且依据ASME PTC6—2004规程对机组性能进行考核验证。试验结果表明:修正后发电机输出功率为53115.9 kW,比设计值(51510.0 kW)高出1605.9 kW,达到了性能设计的要求。
Taking a 50 MW class steam turbine with steam supplement for waste heat utilization as the research object,the measurement method of the steam dryness at inlet of the steam separator was proposed,and the pressure loss of main stop valve and control valve was analyzed.The correction coefficient of generator output power of this type of unit was given,while the unit performance was tested and verified according to ASME PTC6—2004 code.Test results show that the corrected generator output power is 53115.9 kW,which is 1605.9 kW more than the design value of 51510.0 kW.It is proved that the unit performance can meet the design requirements.
