Large particle ash mitigation system |
摘要 |
Embodiments describe an arrangement for reducing the amount of LPA that reaches a NOx reducing apparatus such as a SCR system. The arrangement includes deflection elements, screens, means for dislodging any LPA that might become lodged in the screens, an aperture for removing the ash through, hoppers or collection means and an ash conveyance system. The arrangement is positioned in a region of ductwork with a reduced gas flow such as the SCR reactor. The screens are positioned relative to one another to direct the LPA downward toward an aperture for removal. In one embodiment the positioning of the screens creates a half-trough or inverted pyramid appearance when placed next to a vertical wall in the flue gas ductwork or the SCR reactor. The low point of the trough is in communication with the aperture allowing the LPA to exit the flue ductwork.
