Performance of wood bottom ash in cement-based ...

Wood bottom ash (WBA) is a type of wood waste ash produced as a by-product from the incineration or combustion from wood-fired power plants, pulp and paper and wood-burning industrial facilities. It is the fraternal twin of the most common and popular fly-ash which is obtained from the same process.

Bottom Ash - an overview ScienceDirect Topics

Bottom ash is most often conveyed in a hydraulic system in which the ash is entrained in a high-flow, circulating water system and delivered to an ash pond or to dewatering storage bins. A simplified schematic of a hydraulic system is shown in Figure 6.24 [16].In this system, the bottom ash hoppers are filled with water to quench the hot ash, which may be as hot as 2,400°F, and are usually ...
