Embodiments of the invention can include systems and methods for facilitating varying coal pipes for a pulverized coal burner. In one embodiment, a method for improving operation of a pulverized coal burner (600) is characterised by at least one coal pipe (604) having an inner diameter (608), and an outer diameter (604). The method can include installing at least one sleeve (602) or at least one liner within the coal pipe (604) between the inner (608) and outer diameter of the coal pipe (604), wherein velocity of a primary air and pulverized coal mixture is increased in an upstream portion of the coal pipe. The method can also include reducing the at least one sleeve (602) or liner, wherein velocity (Vexit) of the primary air and pulverized coal mixture is reduced in a downstream portion of the coal pipe.
