摘要： PURPOSE: A gas dispersing plate of a fludized bed furnace is provided to decrease the passage pressure difference of reducing gas, to improve dispersion efficiency by equalizing the current speed distribution of the reducing gas in a radius direction and to save operation cost. CONSTITUTION: A gas dispersing plate formed with plural eruption holes(2) is prepared so that resistance against reducing gas passing through each eruption hole of a board member(1a) is decreased. Herein, the reducing gas supplied from a lower part of a reducing furnace passes through the eruption hole. In passing through the plate member, the passage pressure difference generated on an upper and a lower face of the plate member is decreased. In addition, dispersion effect is improved by equalizing the current speed distribution of the reducing gas in a radius direction so that reactive efficiency is increased on the fludized bed.
