Abstract:

Abstract:The steam pressure, temperature and other parameters of the outlet steam of the platen superheater, the exhaust steam of the highpressure cylinder, the outlet steam of the lowtemperature reheater and the first extraction of the turbine were analyzed and compared. Based on this, the rational steam source selection modes for soot blower of the subcritical, supercritical and ultra supercritical unit were introduced. The economic efficiency of different selection modes was analyzed quantitatively. Combining with the practical operation situations of multiple domestic units, by means of rational selection of steam source for soot blower, the purpose of energy conservation was achieved.
