Abstract: The technical features of the current main coal storing modes in large coalfired power plant were described briefly, and the coal storing technology using paralleling multisquare bunkers was introduced emphatically. Combining with the coal yard extension scheme for 1000 MW units of a power plant in Eastern Guangdong, the technicaleconomical comparison between the paralleling multisquare bunkers mode and other coal storing modes was carried out. The application conditions of coal storing technology using paralleling multisquare bunkers in large coalfired power plant were expounded. 

Key words: coal bunker, multi-bunkers, coal storing technology, applying conditions
