Abstract

The invention provides a pulverized coal rich-lean separation arrangement for an octagonal direct flow anthracite-fired burner with double fireballs, characterized in that each boiler is provided with eight burner groups (10) located at the same elevation, with four burner groups (10) forming a first imaginary tangential circle (11) in the furnace (2), and the other four burner groups (10) forming a second imaginary tangential circle (12) in the furnace (2). Each of the burner groups (10) is divided into two subgroups in vertical direction, with the first burner subgroup (10) being called as a ?primary air/rich pulverized coal" burner and the second subgroup (10) being called as a ?primary air/lean pulverized coal" burner. The invention can allow the furnace wall heat release rate qHr of a burner area to be high and ensure timely ignition of pulverized anthracite air flow and boiler minimum stable load without auxiliary fuel support while meeting the heat power of the whole boiler.
