发电厂“以大代小”模式及直接空冷新技术

The Mode of Replacing Small Units with large onesin Power Plant and the New Direct Air Cooling Technology

在国内以高参数大容量取代中低压燃煤机组实现“以大代小”模式，在国外以燃气／蒸汽联合循环实现“以大代小”模式。两者都可利用直接空冷技术。

In China the mode of replacing small unts with large ones refers to the replacment of coalfired unit by high data and large capacityWhile in foreign countries the mode refers to the realization of gasfired/steam combined cycleThe direct air cooling technology can be well adapted to the case
