| Abstract: | The paper describes how a certain power plant has been using the, at present advanced VDF technique, recal culated and redesigned the clearances of part of its air preheater's sealings, which were then retrofitted into non-adjustable dual sealings. How the retrofit had been effectuated and the special features of the project are also being presented at the same time. Air leakage after retrofit reduced considerable, increasing the boiler's efficiency and the set's loading capability. The economic merits are remarkable. |
