Abstract:
Steam power plants are the most common electric power in the
world. To reduce the cost of generation, Sudanese Thermal Power
Generation Company (STPG) former National Electricity Corporation
NEC has been built.
Garri (4) steam plant has been used Circulation Fluidized Bed boiler
(CFB) technology by burning sponge coke which is produced at
Khartoum Refinery Company as byproduct.
CFB technology depends on fluidization not only to increase the
efficiency of heat transfer from sponge coke to water tube of stream but
also to avoid over heating malting and phenomena pulsation.
Sand is added to sponge coke to keep a certain temperature
homogenizes spread in all Furnace surfaces.
The focus of the research is to calculate the minimum fluidization
velocity (the velocity at which all particles being to float) and bed
particle size at corresponding to temperatures at different operation
status.
In this research study the minimum fluidization velocity by using
applied equation method, practice method and then comparison
between the two methods .
Because these two methods are so difficult and complicated a
computer program was built, and verified known data give immediately
a good result of minimum fluidization flow corresponding bed particle
size and temperatures compared between them and the manufactured
values.
