摘要：
In this paper, it takes the 1000MW ultra supercritical coal-fired unit as the research object and describles the runback process of primary air fan. With the curve, some mainly processes including the amount of fuel, hot primary air pressure of the header, inlet air pressure of each mill, negative pressure of furnace, superheat degree of middle point and feed-water flow were analyzed. The coal-water ratio of primary air fan can provide reference for dealing with the analogic accident by the similar unit. At the same time, some valuable datas can be used during the coal pulverizing system of large electric generation unit.
