PhD Research Proposal

I am intended to do my PhD in the field of reaction engineering (Circulating fluidized bed, CFB)

as I have been involved in the teaching of subjects that are Chemical eaction !ngineering

(C!) " Chemical eaction Design (CD) at undergraduate level in #FC Institute of

!ngineering " Fertilizer esearch Faisalabad since last five years " moreover I have $or%ed in

finding the reaction rate constant &%' for the anionic echange (*+) under the different

o-erating conditions and o-timum removal of heavalent chromium ion in the tannery.tetile

$aste$ater in Pa%istan in my /sc (Post graduate) -rogramme at #FC Institute of !ngineering "

Fertilizer esearch Faisalabad, Pa%istan0

1o the %inetic study of different reactions under various conditions in different reactors in

my field of interest0 In this research, I am interested in %inetic.heat transfer studies in the

Circulating Fluidized Bed (CFB) by coal combustion as there are huge resources of coal -resent

in &2har desert 1indh' Pa%istan and Pa%istan is facing severe energy crises also01o the -ro-er

use of this huge energy source in Pa%istan is im-ortant time necessasity for the -o$er generation

to overcome this energy crisis0 /y -ur-ose of study in this research $or% is to im-rove one of

the follo$ings3

40 2o enhance the heat transfer rate in CFB combustor in its three distinct zones from the

combustion stand-oint3

5o$er zone (located belo$ the secondary air injection level)

6--er zone (located above the secondary air injection level)

7ot gas*solid se-arator (cyclone)

2he objective of this research $or% is to see the effect of bed tem-erature, air staging, and ecess

air and gas velocity on heat transfer, combustion -erformance " hydrodynamic behavior of a

circulating fluidized bed burning coal0 Combustion system needs to be designed " installed0

1econdly, results obtained through the e-erimental $or% $ill be com-ared $ith the develo-ed

mathematical results to see the enhancement in the heat transfer rates0

90 2o s%etch different regimes (2urbulent (2B), Fast fluidized(FF) " the -neumatic

conveying(PC) regimes) " to develo- their -erformance e:uation for our s-ecific case

.any other to develo- a com-rehensive %inetic model to see better combustion

-erformance of coal in CFB0 During these studies for these contacting regimes solids

$ill be entrained out of the bed " $ill be re-laced0
