The disposal and utilization of ash residues from PFBC

Circulating Fluidized Bed Boilers

“…For that reason, sometime low-grade fuels, such as coke breeze or pond slurry, are added to the clay mix for making bricks. Pilot-scale experiments (Carr and Price 1987) have shown bricks containing fluidized bed ash as a fuel additive to have the compressive strength in an acceptable range of 10-30 MPa.…”

“…These fillers are used to increase the volume of the product while retaining the mechanical strength within a reasonable limit. No processing difficulty is reported (Carr and Price 1987) in adding up to 60 % fluidized bed ash in polypropylene and 40 % in polyurethanes. The mechanical strength of the polymers is, however, compromised.…”
