During startup and shutdown process of the units with large capacity and high parameters
the auxiliary steam is usually used as seal steam supply.Thus
the construction investment and operation cost will have to be increased.In order to reduce the investment and operation cost in Huaneng Hegang Power Plant
transformation on draining system of main steam and reheat steam were conducted.Moreover
the startup and shutdown operation procedure was also modified.After the improvement
the unit realized startup and shutdown with no auxiliary steam.Besides
the investment and operation/maintenance cost of the boiler's startup was dramatically saved.
