Particle size analysis of Fly ash Variation of pH with mixing time for Rheogram of mixed fly ash slurry
(ESP-1 + ESP-2 + Bag-filter) with best coal sample (ESP-1 + ESP-2 + Bag Filter)
Bottom ash samples (Best Condition) with 10% bottom ash, at CW = 55%

Feasibility study on combustion of pet-coke coal fuel mix in a fluidized bed reactor & reduction
of emission through appropriate dosages of chemical reagents during combustion.
The R&D project has been taken to study the SO2 gas Characterization studies of coal, petcoke & limestone
capture efficiency during combustion and further improve samples were done. Proximate/Ultimate Analysis of
it through steam injection. Petcoke samples were collected Petcoke & coal, PSD, Particle density and Chemical
from M/s IOCL Paradeep refineries & M/s Hindalco composition of limestone were determined. Cold model
Industries, Sambalpur and limestone samples were studies for reactor design have been carried out. A lab-
