| Abstract: | Aiming at the problem that negative expansion difference is big and over the limit whenthe units extreme hot start of 65 MW unit after the commission in TJK Power Plant of Indonesia,finds out the main causes by technical analysis,frames the improvement project and puts in heavyrepair practice. The improvement result shows that the project solve problem of negative expansiondifference is big when the units in extreme hot start,after heavy repair the unit realizes start-up andshut-down at any time. |
