The situation of localization for manufacturing power generation equipments used in Huaneng Power Plants has been presented and reviewed.The rapid development of power generation equipments used in Huaneng Power Plants

from technologies being initially imported from abroad and being manufactured at home to all being domestically researched

designed and manufactured

from capacity of unit being 300 MW to capacity of 1 000 MW

and from unit of subcritical parameter to unit of ultra-supercritical parameter

has been achieved.At present

the indices of units

such as condition of equipments

efficiency in operation

and coal consumption in power generation etc.

all have reached the advanced level over the world.In addition to the entire units

the localization of manufacturing auxiliary equipments and parts

such as feed-water pumps of boilers

pipelines

heating surface tubes of boilers

air-cooled condensers

diesel generators

automatic control systems

rotor forgings for steam turbines

excitation systems

resins for condensate polishing treatment

flue gas desulpurizaton systems

and all kinds of valves etc.

has also been presented.
