Tip leakage aerodynamics over stepped squealer tips …

2011-1-1 · The mid-chord leakage flow pushes the leakage flow separation line out of the tip gap exit, but this mid-chord penetration occupies a very narrow area. The downstream leakage flow penetration is so strong that the leakage flow separation line is located farther away from the tip gap exit and its occupation area is much wider than the mid-chord one.

Bottom Ash

McEnroe and Schroeder (8) have shown that the leakage or leachate rate through the drain layer is related to its degree and depth of saturation. With BA''s lower permeability of approximately 10 −4 to 10 −5 cm/s compared to typical daily and intermediate cover material permeabilities reaching 10 −3 cm/s—the amount and depth of saturation will be reduced.

Bottom Ash

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.
