Bottom Ash an overview ScienceDirect Topics
Bottom ash is the residue that is fused into heavy particles that drop out of the furnace gas stream (air and combustion gases). Table 10.3 presents the chemical composition properties of bottom ash. These particles are formed at the bottom of the furnace. Bottom ash consists of coarser and heavier particles than fly ash (Torrey, 1978).The color of bottom ash ranges from gray to black.
