Provided is a fuel supply pipe structure that can be compactly configured even when interchanging a biomass fuel and a coal fuel in the operation thereof, with equipment being shared as much as is practicable. The fuel supply pipe structure comprises: an upper pipe (49) that is connected to a fuel supply device (50) for supplying unpulverized fuel in a prescribed supply amount; a lower pipe (45) that is connected to a pulverizer (5) and conducts fuel to the pulverizer (5); and an exchange unit that is provided between the upper pipe (49) and lower pipe (45) and enables exchanging of a rotary valve (47) and a short pipe. 本发明提供一种即使在切换生物质燃料与煤炭燃料来进行运用的情况下，也能够尽可能地共享设备而紧凑地构成的燃料供给配管结构。所述燃料供给配管结构具备：上部配管(49)，与以规定的供给量供给粉碎前的燃料的燃料供给机(50)连接；下部配管(45)，与粉碎机(5)连接而将燃料引导至粉碎机(5)；及替换部，设置于上部配管(49)与下部配管(45)之间且被设为能够将回转阀(47)与短管进行替换。
