Abstract
A char removal pipe including a removal pipe (22), a perforated plate (26) that partitions the interior of the removal pipe (22) into a powder channel (29) and a gas chamber (30), and an assist gas supplying device (28) that supplies an assist gas to the gas chamber (30). The perforated plate (26) is formed so that the pressure loss when the assist gas flows from the gas chamber (30) to the powder channel (29) through the perforated plate (26) is greater than the pressure loss when the assist gas flows through accumulated powder formed by the accumulation, on the perforated plate (26), of powder flowing in the powder channel (29).
