Abstract
This thesis is intended to develop a mathematical model which can predict the flame
length and flame temperature of rotary lime kiln which are two main parameter
controlling heat transfer process in the flame zone ofthe kiln and their influence is
reflecting to the quality and quantity of the lime produced.
The theoretical part of this study focus on the production of quicklime including raw
material for lime burning and the influence of physical properties and chemical
composition of limestone on the rate of calcination and on the quality of lime
produced. Also the different types of fuel, the calcinations process, chemical
reactions, and kinetics of calcinations, heat requirements, and product quality have
been discussed in this part.
Also in theoretical part development of lime kilns and different type of kilns used in
lime burning have been pointed out and more details have been given for the rotary
kiln, case study, and its types and parameter control.
The practical part in this thesis focus on two main subjects, first one is the model
development using EXCEL and the series of equations used including equations of
different types of heat transfer in rotary kiln and their related assumptions. Also in
this part the results obtained from the model had been compared with experimental
values of a rotary lime kiln and comparison curves had been made to access the
validation of the model.
The second subject is the burning parameter optimization; the main two studied
parameters are given here under:
1- The influence of increasing primary air on the axial temperature profile of the
flame, maximum flame temperature and flame length.
2- The influence of increasing volumetric flow rate of fuel on both flame length
and maximum flame temperature.
On completion ofthis study the most likely outcomes are:
1- Using 30 % primary air is giving a small error percentage (less than 6 %)
between the calculated and the experimental values ofthe flame temperatures.
2- Increasing fuel volumetric flow rate will increase both flame length and flame
temperature.
3- Increasing % primary air will increase flame temperature but reducing flame
length.
