| Abstract: | T23 steel waterwall leakage of 1 000 MW tower-type boiler frequently occurs in the region of 48-70 m. An analysis is conducted on the causes of T23 steel waterwall leakage of the Ninghai 1 000 MW ultra supercritical boiler unit and some counter measures are proposed, which has eliminated the hidden leakage trouble of waterwall and reduced the times of unplanned unit outrage. |
