Abstract:
This research–work aims upgrading and improving the Existing
upper- Draught Kiln Temperature Distribution, Reducing the Drying
Cycle period by utilizing of the Kiln Hot Gases, and Improving both
the kiln and dryers productivity and quality of Soba Brick Pilot Plant,
.which is one of the existing modern brick factories in the Sudan
This work summarizing the immeasurable research– work and
studies previously under taken by numerous contributors in the field
of Brick- Firing and Drying, mainly at the Building and Road
Research Institute (BRRI) of University of Khartoum. The documents
included the types of Kilns being used, beginning from the old
primitive ones up to the new modern fully automatic ones, with their
.different characteristic and specifications
Extensive field – work and laboratory studies including all the
different proposed modifications and improvements during this work
were being fully applied and used during the factory operation,
.confirmed better obtained results
The out–come of these experimental studies results were deeply
:very effective, that is to say
The plant productivity had been increased up to 60%
.1
instead of 20% with a minimum losses at the dryers and
.the kiln (3%) and (2%) respectively
The drying period in the dryer was reduced to only 4 days
.2
.as designed instead of 10 days or more
Utilization of the kiln hot gases in drying process increased
.3
.(the kilns efficiency up to (67.4%) instead of (38%
The existing upper- draught kiln was simply modified to
function like on efficient down-draught one without
affecting its building structure, avoiding the high cost
required for the needed civil work. Then about 7.5 million
.Sudanese pounds will be saved
.5
Fully information had been collected about the vertical
shaft brick kiln (VSBK) at Soba. It can be easily completed
.and work as a new type of kilns in the Sudan
.6
This research–work results will support the idea of BRRI of
:University of Khartoum to fulfill its main objectives
First as a central consultant of Building Materials
.a
.development unit in the Sudan
Secondly there will be an international contribution and
technology transfer on building materials development
.with the other similar Institutes
