Abstract
Virtually all activities of man is centered around conversion of energy from one form or
type to another. From the basic functioning of human body mechanism to all practical
activities of man starting from burning of wood to generate heat during stone age to latest
satellite communication all involve energy transformation.
The inter-convertibility of all forms of energy and their guiding laws have been
established by basic thermodynamics, mechanics, electrostatics and electrodynamics
theories. However, the theories are either not explicit enough to be subject-able to
verification, where available they are dispersed in various literature.
Owing to the importance of energy conversions it has been considered as worthwhile to
collate the energy conversion data expressions and present them in a manner that lends
itself to easy application. Test the equations so made available by applying to practical
situation in a running processing outfit, a case study of SUNSEED Nigeria PLC.
A very wide variety of literature sources were consulted ranging through virtually all
areas of science.
First, preview of historical developments and milestone discoveries of energy conversion
systems by scientists from seventeenth to the twentieth centaury was carried out. The
laws developed were presented in form of mathematical expressions.
Energy forms and types were classed and presented as mathematical expressions in terms
of measurable parameters.
Case study of energy conversion from chemical, mechanical and thermal energy as input
to Electrical energy. Diesel powered, 1500kVA generators at Sunseed Nigeria
PLC(edible oil division) Zaria, was analyzed using some of the expressions generated.
First law analysis of the conversion efficiency was carried out with a view to identifying
areas of energy waste due to inefficiency of conversion, first law efficiency of conversion
was found to be 70.03 %
Cost comparison of a unit of electricity N40.62/kWh when generated using the diesel
powered generator appear grossly uneconomical when compared to N 8.50/kWh, price
sold by Power Holding Company of Nigeria (PHCN)
