Through study on features

application and development state of air-cooled units

and combining with experiences in design

manufacture

and construction of 60 MW and 100 MW wet cooled ultra-supercritical units in our country

as well as analysis carried out by domestic manufactures for the progress of key technologies in research

development

and design sectors of large-scale air-cooled units

it is believed that the development of large-scale air-cooled units is feasible at present.At the same time

indices of the large-scale air-cooled units

such as water-saving rate

coal consuption rate

etc.

have been analysed

pointing out the necessity and feasibility of developing large-scale air-cooled units in regions of water shortage and coal abundance.
