| Abstract: | Aiming at the domestic 600 MW supercritical once-through boilers in Guangdong Datang International Chaozhou Power Plant, the scope, scheme, technological process and the quality acceptance standard of steam pipe blowing were analyzed, and the parameters of steam pipe blowing selected. There were two phases of pipe blowing by steam, steady pressure for the first phase while the combination of steady pressure and falling down pressure for the second. The pipe blowing was successful with the prospective effect achieved, which accumulated experience for comprehensively using steady pressure and falling down pressure in pipe blowing of supercritical once-through boilers. |
