| Abstract: | The economical index of pre-and post class A maintenance is obtained from the thermal diagnosing test.300 MW under isolation condition,the corrected heat rate decreases 122 kJ/kWh.After class A maintenance,the HP efficiency is 84.02%,which is increased by 2.08%,compared with that of pre class A maintenance.The IP efficiency is 91.44%,which is increased by 0.64%.The LP efficiency is 90.33%,which is increased by 0.77%.According to the test data,the effect of Class A maintenance is evaluated. |
