| Our country is a coal-fired power generation as the main way of electricity production country,million kilowatt coal-fired generators as currently the world’s most advanced coal-fired generating set,with the national power industry "big pressure on the small" strategy,will gradually over a period of time in the future become the main form of the coal-fired power in our country.This paper the author participate in two induced draft fan energy-saving renovation project of a power plant: "induced draft fan a merger with desulfurization booster fan" and "small steam turbine driving induced draft fan",the two renovation project of necessity,feasibility,retrofit scheme,parameter selection,control policy,economy and so on to comb,and the two scheme is applied to a unit at the same time the energy saving effect,according to the millions of mw coal-fired generating set energy saving induced draft fan to realize the depth of a comprehensive renovation plan. |
