| description | To provide compatibility between combustion efficiency and suppression of transport problems of sludge fed to a heating furnace.SOLUTION: A sludge feeder pertaining to an aspect of the present disclosure is an apparatus for feeding sludge to a furnace that heats cement raw materials. This sludge feeder has a hopper that contains sludge, a screw feeder that feeds sludge in the hopper downstream by rotating a screw in an internal space connected to an outlet of the hopper, and a pouring part that supplies liquid at least to the portion of the internal space connected to the outlet. The pouring part supplies liquid to the connection portion so that when the connection portion is partitioned into two virtual areas at the center in the sludge feeding direction, the amount supplied to one area located upstream is greater than the amount supplied to the other area located downstream.SELECTED DRAWING: Figure 5
【課題】加熱炉に供給される汚泥の輸送トラブルの抑制と燃焼効率との両立を図る。【解決手段】本開示の一側面に係る汚泥供給装置は、セメント原料を加熱する加熱炉に対して汚泥を供給する装置である。この汚泥供給装置は、汚泥を収容するホッパと、ホッパの排出口に接続された内部空間においてスクリューを回転させることで、ホッパ内の汚泥を下流に送り出すスクリューフィーダと、少なくとも内部空間のうちの排出口との接続部分に液体を供給する注液部と、を備える。注液部は、汚泥を送り出す方向の中央で接続部分を２つの仮想的な領域に区画したときに、上流に位置する一方の領域への供給量が、下流に位置する他方の領域への供給量よりも多くなるように、接続部分に液体を供給する。【選択図】図５ |
