Wood
biomass is a potential alternatives source of energy for electricity generation
if well Harnessed. This is due to its prospect in the production of fuel having
high calorific value that can be used to drive a steam turbine in the
production of electricity. This study shows the Performance and evaluation of
the heating values of wood biomass for use in steam thermal power plant.
Biomass (wood wastes) from six tropical
species, Iroko (Melicia Exclsa),Omo(Cordial Platythyrsa), Obeche
(Tripochiton Scleroxylon), Afara
(Terminal Superb), Ayin (Anogeissuseleio Carpus), Abura (Mirangya Cilita)
collected from twelve(12) sawmills in
Akure metropolis Ondo state in south west Nigeria, were used as a feedstock.
The proximate and ultimate analyses were performed to access the energy
characteristics of the collected wood samples according to the procedure of
American Society Standard Test Material (ASTM) for ultimate and proximate
analysis ASTM E870-82. A computer program (MATLAB) was developed to determine
the calorific value, volume of air, consumption of water and steam require
in powering a 1.0 MW-h steam thermal
power plant (Model). The results from laboratory experiments and energy
calculations from the model revealed that the six wood species used in this
study contain relatively low moisture content and ash content, high proportion
of volatile matter and high calorific value, low level of sulphur as well as a
sufficient high value of thermal energy potential. The boiler efficiency, mass
of air, volume of air, steam consumption of the six samples of wood at
different air fuel ratio were determined. Furthermore the model required 7.985
kg/h of wood waste, 13.206 kg/h mass of water, 1.86 factor of evaporation and
7.1 kg/h of steam consumption. The volume and mass of air require is 58.297
m3/h and 318.813 kg/h respectively.
