In this paper, it takes the 600MW coal-fired unit of Guangdong as the research object. On the premise of safety operation of the unit, the operation oxygen of unit is optimized and remarkable economic efficiency has been achieved. Both the economic efficiency of desulfurization system and the environmental properties of unit are included beside boiler, when compared with the traditional method, the...
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...
