CHAR REMOVAL PIPE

摘要

Provided is a char removal pipe comprising 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).

1. A char removal pipe comprising:
a removal pipe; a perforated plate that partitions the interior of the removal pipe into a powder channel and a gas chamber; and an assist gas supplying device that supplies an assist gas to the gas chamber, wherein the perforated plate is formed such that a pressure loss when the assist gas flows from the gas chamber to the powder channel through the perforated plate is greater than a calculated pressure loss calculated based on a pressure loss when the assist gas flows through accumulated powder that is formed due to powder flowing through the powder channel being accumulated on the perforated plate.
